Dyer, M. J. "Beach profile change at St. Clair beach, Dunedin". Thesis, University of Canterbury. Geography, 1994. http://hdl.handle.net/10092/7969.
Testo completoAbstract (sommario):
This thesis examines the nature of changes that occur within the beach profile at St. Clair Dunedin on the south coast of the Otago Peninsula. The profile changes are linked to variations in the wave and wind environments, and the results are compared to both previous local work and to the relevant theory and models accepted in the literature.
Erosion at St. Clair occurs during extended periods of strong southwest winds which are associated with increased wave heights, decreased periods and enhanced longshore currents. Under these conditions sand is transported both offshore and alongshore to the east, away from the western St. Clair corner, resulting in a lowering of the beach profiles. Erosion is accentuated at St. Clair by the presence of a sea wall, resulting in exceptionally low profiles which may allow fill to be eroded fom behind the concrete seawall face.
While erosion is shown to be associated with predominantly steep waves, ( > 0.09) accretion at St. Clair was shown to often be unrelated to wave steepness. Within the significant accretion periods the longshore current direction was considered to be of greater importance. Thus currents moving to the west under the influence of easterly quarter swells transport sand in to the western St. Clair corner. The presence of the western headland blocking these currents results in rapid deposition, and accretion of the St. Clair profiles.
Allen (1985) showed that the critical wave steepness equation of Dean (1973) applied for a medium sand beach. The equation was shown not to apply to inshore data for the south coast of the Otago Peninsula. This was considered to be due to the higher wave energy experienced on the Otago Peninsula. The failure to gain a critical wave steepness was considerd to be due to the inconsistent survey base, and the fact that at St. Clair the accretional periods were influenced primarily by longshore sand transport over wave steepness.

This project consisted of a series of short stories which worked together creating a larger fictional piece in the form of a non-continuous narrative. This non-continuous narrative is in the tradition of Sherwood Anderson's Winesburg, Ohio, and Louise Erdrich's Love Medicine. The stories in this type of fiction are connected by similar themes and settings, allowing the reader to participate directly in the creative process. The reader helps create the fiction by drawing his or her own conclusions about the characters and places from between the individual stories. By involving the reader more directly in the outcome, this type of narrative creates a more emotional response to the work. Each of the stories in this project were set in a town called Sand Beach, Michigan, and involved four generations of women in a single family. The major themes of the stories were mother/daughter relationships, healing, and redemption. Common images in the stories presented were, Lake Huron, the town of Sand Beach, and a rock in the local region bearing Native American petroglyphs Each of these images participated in the development of the common themes.Department of English

Testo completoAbstract (sommario):
Seagull Beach is a creative work about a woman who moves to a seaside town. While there, she is befriended by an artist and volunteers at the aquarium. The woman, Shell, becomes involved in a mystery involving drug smuggling and murder. Shell and her friend, Linda, solve the mystery through a series of unexpected events. Chapter one establishes Shell in Seagull Beach and introduces Linda. The plot begins with a mutilated dolphin on the beach and the appearance of a bald-headed man. Chapter two takes the reader into the aquarium and expands the cast of characters. The plot is further developed during a party scene when an angry exchange is overheard by Shell. The plot thickens, in chapter three, with the meeting of three men in an all night cafe. Later on, Shell sees a picture of the mysterious bald-headed man, in the local newspaper. Chapter three ends with the discovery of Roger's body. Chapter four has Shell and Linda trying to make some sense of Roger's death. Shell receives Roger's diary on the afternoon of his funeral. Chapter five is an important chapter for this work. It is here that we get a glimpse of a drug encounter that sets up the following scene between the drug smugglers. The use of dolphins as drug runners is also established. In the final two scenes, Shell's RV is ransacked, and the man who killed the dolphin is also killed. The suspense heightens in chapter six as Shell and Linda break into Roger's office. Shell later sees the drug delivery take place and has a confrontation as she walks across a dark parking lot. The work ends with an unexpected revelation and a conversation between Shell and Linda.

After compiling an appropriate list of beach criteria from established award programs and experts, the research landscape architect observed the Virginia Beach Resort Zone for areas of intense beach user activity. The resulting analysis of these "hot-spots" indicated that urban resort beach users visiting the recreational beach during high-use times tended to gravitate toward locations on the resort beach which were close to three needs: public parking, public restrooms, and inexpensive refreshments. This pattern shows the apparent preferences of many beach users for certain amenities.Master of Landscape Architecture

Testo completoAbstract (sommario):
As a pilot study into questionnaire investigation of beach user opinions and perceptions, a survey was conducted of users of four beaches (Southerndown, Nash, Ogmore and Llantwit), at the Glamorgan Heritage Coast, Wales. Beach perceptions were assessed in terms of socio-demographics, psychological parameters (Eysenck Personality Questionnaire and Spielberger State-Trait Anxiety Inventory) and related to the existing beach environment. Few changes to general facility provision could be recommended, but a number of management recommendations were made. Beach user gender, socio-economic status, planned length of stay and anxiety/neuroticism level were shown by discriminant function analysis to influence beach selection. A beach rating scheme was developed, based on a novel beach user questionnaire/checklist system. This questionnaire was used to interview users (n = 859) at 23 randomly selected Welsh beaches with regard to preferences/priorities for a wide range of beach aspects. Questionnaire data analysis generated scores which could be applied to checklists appropriate to other beaches of various commercialisation levels. Seventy Welsh beaches were assessed, producing scores from 39% (Porthcawl - Trecco Bay) to 69% (Broadhaven, S. Pembs. and Pembray). Landscape was assessed by panel judgements of a video panorama sequence, with scores for this aspect ranging from 19% (Prestatyn) to 80% (Broadhaven, S. Pembs.). The rating scheme took into account a larger number of beach aspects (47) than any beach award/recommendation in common use in the UK. It successfully took account of differing beach user preferences/priorities for various beach aspects and also the differing beach user demands at commercialised as opposed to undeveloped beaches. Many differences in beach user preferences/priorities were observed according to differences in stated preferred beach type, many of which could be important for management. In addition, pilot scale studies were undertaken at the Costa Dorada, Spain and on the Turkish Aegean Coast. For the latter, beach rating was also carried out. Future studies aiming to use stated perceptions, preferences and priorities of beach users to guide management should take account of possible influences such as beach user familiarity, expectation, cultural background and past experience. Much further work is required to develop beach user questionnaires to investigate aspects of beach user perception. Future rating exercises based on beach user preferences/priorities should take account of the need for beaches to meet minimum standards for the most important (as identified by beach users), beach aspects, in order to achieve a high rating or grade. The limitations of beach user surveys in terms of sampling difficulties need to be addressed. For valid management decision support, other stakeholders such as residents, tourist trade workers and those choosing not to visit beaches in particular areas need to be reached using other investigative methodologies.

Testo completoAbstract (sommario):
Tailings (mining waste) disposal is a significant consideration for the mining industry, with the majority of the ore processed in most mining operations ending up as tailings. This creates large volumes of tailings, which must be handled and stored responsibly to avoid potential environmental catastrophes. The most common form of tailings storage facility is the impoundment, where tailings are contained within a basin, with beaches forming around the perimeter of the impoundment and a pond standing in the middle. A relatively new method of tailings storage is to create a 'stack', whereby the tailings solids form a large heap, with the discharge of tailings slurry from the apex of the heap. It is of significant value for mine operators and tailings engineers to be able to predict the shape of the beach that forms in either of these disposal scenarios. The key to being able to do this relies on a method of prediction of the beach slope. The aim of this work is to develop a method of tailings beach slope prediction for tailings slurries that are sub-aerially discharged from a pipe. In this thesis a literature review is undertaken, investigating existing methods for the prediction of tailings beach slopes. These methods are validated against relevant industrial and experimental data. Two separate phases of experimental work have taken place in an effort to investigate tailings deposition behaviour, one at mine sites and the other in a laboratory on a small scale. Three new tailings beach slope prediction models are presented; a simple empirical model enabling quick approximate predictions; an a priori tailings beach slope prediction model based on existing theories of open channel flow, sediment transport and rheology, which is more powerful due to the greater degree of theory in its foundation; and a new semi-empirical model that shares some of the theoretical aspects of the a priori model but offers better predictions due to its empirical calibration to the experimental data. The experimental results, along with 3 other independently collected sets of relevant industrial and experimental data, are used to validate the beach slope prediction models found in the literature, as well as the new beach slope models presented in this thesis. Statistical evaluation of the performance of all of these models is presented to enable comparison. Finally, a new beach shape model is presented for the three dimensional geometric forecasting of the beach surface of a tailings stack. Historic tailings discharge data is run through the beach shape model, and the shapes predicted by the model are compared with aerial survey data of a real tailings stack for validation of the shape model. This work not only presents a new method of tailings stack shape prediction, but also a plausible theory for explaining the concavity of tailings beaches. The stack shape model also has the potential to be developed further for the three dimensional modelling of tailings beaches formed in other types of storage facilities, such as impoundments or valleys.

Testo completoAbstract (sommario):
Urban development and human encroachment on the natural habitats along the coastline of Florida combined with invasive exotic pressures have resulted in the fragmentation and degradation of habitat quality within Broward County. Native habitats have been significantly altered and fragmented to a fraction their previous size. With loss of habitat area and quality, isolation of breeding populations and anthropogenic pressures, it is important to determine species composition and habitat utilization in order to conserve the remaining biological diversity. It was the intent of this study to determine the small mammal species’ population structure and habitat utilization by season in the four sampled habitats. Previously undocumented species and/or extralimital populations were predicted prior to sampling.
John U. Lloyd Beach State Park in Dania Beach, Florida is an understudied location for small mammals. This study surveyed four terrestrial habitats for small mammal species using live trapping and mark/recapture techniques. Data were collected monthly over the span of thirteen months to determine habitat use from maritime hammock, mangrove swamp, coastal dune and ruderal habitat types to determine species composition and mass of individual captures and recaptures.
Trapping (3749 trap nights) produced twenty-four captures (including recaptures) in two of the four habitat types: maritime hammock and coastal strand. No animals were captured in the mangrove swamp or ruderal habitats, both of which were dominated by invasive Australian pine (Casuarina equisetifolia) monocultures.
Post study, a large habitat restoration project restored the habitats impacted by invasive exotic flora. This survey serves as a baseline for small mammals in the park, documenting the pre-restoration habitat use and species composition. Future study to determine changes in species composition post-restoration is recommended.

Fallon, Kathleen Michelle. "Rip Current Formation and Beach Safety Implications for Several U.S. Atlantic Coast Beach Areas". FIU Digital Commons, 2017. http://digitalcommons.fiu.edu/etd/3382.
Testo completoAbstract (sommario):
This dissertation combines seemingly different studies, which work together to describe the physical characteristics of rip current development and associated social implications at several locations. These fast-moving, concentrated flows of water travel offshore and can be found on any beach with sufficient wave action. Any event of increased wave steepness will erode a large quantity of sediment from the beach. The material deposited offshore eventually makes its way back; during this process, ocean water becomes trapped behind a shore-attached bar resulting in a ridge-and-runnel. These formations are seen at East Hampton, where rip-like currents form as concentrated water drains from the runnel through a breach in the ridge. Camera images from 2010-2016 captured ridge-and-runnel formations and the ensuing currents. These newly described rips behave similarly to bar-gaps; however, they are not directly related to wave action. Coastal scientists consider rip currents to be the number one hazard at most beaches. In Palm Beach County, two traditional rip types were studied: bar-gap and structurally-controlled. Lifeguard incident reports from 2011-2016 were used to correlate wind speeds and wave heights to rip related rescues at three beaches. This research was undertaken in an effort to determine under what conditions most beachgoers become caught in this hazard. Rip currents were seen to be the most dangerous to bathers on days with moderate wind and wave activity. The same beach states that lead to the strongest rips also tend to keep beachgoers from entering the ocean. A social survey at Miami Beach, from 2011 to 2012, quantified beachgoer’s rip knowledge and their recognition of hazards. A significant portion of the respondents showed insufficient knowledge, which indicated they are at-risk of being caught or drowning in a rip current. Frequent exposure to the beach, maturation, and residency were identified as the main contributors to one’s literacy whereas education was the only variable that influenced a beachgoer’s visual recognition of hazard. The information gathered by these surveys can aid in creating better rip current awareness campaigns targeted to demographics that were determined as the most at-risk. An understanding of the physical and social science of rip currents can mitigate the impact of these beach hazards.

Testo completoAbstract (sommario):
A study of beach profiles and sediment activity has been undertaken investigating natural beaches of inner coastal southwest British Columbia and published data on laboratory beaches. Two separate types of sediment activity are focused upon: longshore sediment, activity occurring on inner coast beaches and on- offshore sediment activity occurring on wave Hume constrained laboratory beaches.
Field investigative work on twenty-five natural beaches has included review of past-field studies, profile surveys, sediment tracing experiments, investigation of surface and subsurface sediment, size distribution and structure, measurement of slopes and elevations of shoreline features, review of available wave climate data and wave hindcasting for the period of profile surveys. The work has shown that inner coastal beaches are predominantly shingle beaches or cobble armoured beaches with longshore sediment transport, occurring in a narrow upper foreshore zone under wave action at high tides. There is also evidence that coarse materials (gravels and cobbles) move selectively in an onshore direction and fine materials (silts and sands) move in an offshore direction. The sediment transport processes and beach characteristics identified are different from the summer/ winter beach process known to occur on open coasts.
Laboratory beaches have been studied to identify the general response of a beach profile to waves. One problem in the study of beaches has been the lack of a readily measured variable to interrelate wave action and sediment movement. By studying laboratory
beach profiles a variable representing on-offshore sediment, movement has been abstracted as an area swept out by differencing two profiles as a function of time. The variable has been investigated using laboratory beach data and correlation between it and wave parameters such as height, and period is evident. A dimensional analysis of on-offshore sediment transport is performed using the swept, area variable.Applied Science, Faculty of

Testo completoAbstract (sommario):
Concurrent wave and morphology data were collected arow1d a coastal protection scheme on the U.K. south coast. The scheme consists of eight detached breakwaters protecting a renourished sand and shingle beach, and is situated in a strongly macro-tidal environment. The development of the beach morphology is described. The beach trapped sand and shingle moving eastwards into it, and lost material from the eastern end. While the beach was designed to maintain a shingle beach, it was found that the scheme was most effective at trapping sand, which led to tombolo formation behind the updrift breakwaters. Current engineering design methods for describing beach development were applied to the scheme. Empirical techniques were found to be poor predictors of the salient length, although the simplest methods were reasonable guides to the scheme response over a variety of tidal levels. The US Army Corps of Engineers one-line model GENESIS (Hanson, 1989) was applied to the scheme. Using observed values of beach, structure and wave conditions, it was necessary to exaggerate transport due to longshore gradients in wave height relative to transport due to oblique wave approach to correctly describe salient formation. While it was possible to reduce model calibration errors, model validation was not successful. This was due to the inability of the model to allow tombolo formation, and also due to the lack of a 'constant' beach profile, due to the different behaviour of the sand and shingle. Empirical orthogonal function analysis was carried out on the beach survey data. From the limited records available, it was clear that the scheme reduced profile variance behind it, compared to the updrift and downdrift shorelines. The scheme also led to more complex 3D seasonal movements of beach material, in contrast to the predominantly 2D response updrift.

Testo completoAbstract (sommario):
The aim of this project was the evaluation of performance of beach handball players.
Beach handball is considered a high-intensity mixed-metabolism sport where the performance depends on the combination of high-intensity physical patterns at player and team level. The player performances depend on specific movements involving speed and power, rapid accelerations and decelerations, and changes of directions, whereas the overall team performance depends on technical and tactical team performance indicators, such as passing, catching, throwing, and blocking during offensive and defensive situations.
The first part of this dissertation aimed to examine the differences between male and female players during shooting actions occurring during semifinal and final phases of a European Beach Handball Tournament by means of notational analysis. For the study 9 matches were analyzed. Overall, 559 (males: 353; females: 206) shots were observed; 54.7±9.4% were successful and 19.9±7.1% were saved by goalkeepers. No difference for gender emerged. Results showed that notational analysis represents a valuable tool to examine many aspects of shooting actions such as the shooting technique, the shooting area, the area of the goal to which the shots end in relation to players and goalkeepers’ efficiencies.
To improve players’ performances and to understand the level of adaptation to a given training program and minimizing the risk of non-functional overreaching, monitoring players’ load plays a fundamental role. For this purpose, the second part of this dissertation focused on the investigation of internal (assessed using objective and subjective methods) and external loads experienced by youth male beach handball players during training sessions and competitions. Thirteen players from the Lithuanian U17 beach handball team were monitored across 2 training camps (14 training sessions) and during the Younger Age Category 17 European Beach Handball tournament where players were involved in 7 matches. For the external load inertial movement units devices units were used while the internal load was objectively recorded by means of heart rate (HR) monitors. After each session, the HR data were exported, and the individual workload was calculated according to the summated HR zones (SHRZ) method. Furthermore, the internal load was subjectively assessed by means of Rating of Perceived Exertion (RPE) scale by asking each player “How hard was your training/Match?” 30 min after the completion of the session. Successively, the session RPE (sRPE) workload was calculated by multiplying the individual RPE score for the duration of each session.
Subjective perception of internal load experienced by youth beach handball players increases with the objective internal load. However, the increase varies between players and sessions.
In addition, results showed that external load variables (PlayerLoadTM, accelerations, low intensity events, medium intensity events, high intensity events, jumps, and changes of directions) showed a strong correlation with sRPE and SHRZ. The variable with the highest relationship and predictive capability, with both SHRZ and sRPE, was PlayerLoadTM.
Further investigation should examine any potential difference in players of different ages and explore the influence of other contextual factors such as the match outcome or the individual players’ fatigue.

Testo completoAbstract (sommario):
The nearshore zone is plenty of 3D morphodynamic patterns resulting from the interaction of waves, currents and sediments. The dynamics of formation and evolution of these patterns is at present a controversial point in coastal research. However, frequently nearshore zone shows a strongly persistent uniformity. In this situation, morphodynamic changes are dominated just by crossshore processes. Remarkably, although this situation displays much less morphological complexity, cross-shore beach profile morphodynamics is still a research challenge, as sediment transport, in this case, is the result of a very subtle balance between onshore and offshore directed forces that still remain unsolved. The aim of this thesis is to get more insight on the physical processes involving cross-shore beach profile evolution and how relevant are them in the nearshore zone morphodynamics.
To this end, a 1D non-linear morphodynamical model for the evolution of the profile is developed to analyze some relevant aspects of cross-shore beach profile morphodynamics. The AMORFO70 model couples hydrodynamics, sediment transport and bottom changes to account for the morphodynamics feedback. The model considers the depth-integrated and wave-averaged momentum and mass conservation equations coupled with wave- and roller-energy conservation, Snell's law and the dispersion relation under the assumption of alongshore uniformity.
It is well-known that the intra-wave processes, particularly the near-bottom orbital velocity and acceleration, can lead to net onshore sediment transport. The model accounts for the most novel parameterization of the near-bed intra-wave velocity, to analyze the effects of the temporal distribution of the intra-wave near-bottom velocities and accelerations on cross-shore morphodynamics. It is found that accounting for both velocity and acceleration skewness in the sediment transport is essential to properly simulate onshore sandbar migration and the entire profile evolution. Results have shown a strong spatial dependence of sediment transport along the profile, in such a way that in the shoaling zone transport is mostly driven by bed-shear stress (velocity skewness) and the breaking and inner-zone transport is dominated by pressure gradients (acceleration skewness).
The accurate description of sediment transport is a key issue in morphodynamic modeling. The model has been complemented with several transport parameterizations to analyze the differences between morphodynamic predictions related to different sediment transport formulas for different sequences. Results evidenced several differences between the predicted transport rates and also between the predicted incipient bottom changes of the different sediment transport formulas.
It is found that the cross-shore morphodynamic predictions depend strongly on the sediment transport formula that is used and not all of them capture the expected trends. Particularly, formulas that account directly for the effects of wave velocity and acceleration skewness lead to the best predictions, especially for accretionary sequences.
A common procedure on cross-shore beach profile morphodynamic modeling is to neglect the alongshore variability. This assumption has been analyzed for the prediction of the mean profile evolution on the short-, the mid- and the long-term. It has been proven that the model is able to reproduce short- and mid-term evolution of the mean profile with substantial accuracy. Thus, considering the mean profile as the average of the evolution of individual profiles along the shoreline leads to the best results, as 'a way to account for the alongshore variability'. In the long-term it is found that, although predictions may agree with measurements, they do not capture the real morphodynamics. This stresses the relevance of analyzing the behavior of the simulated morphodynamics during long-term evolution to avoid mistakes in the interpretation of the model capabilities.La zona costanera és plena de patrons morfodinàmics 3D que són el resultat de la interacció de l’onatge, els corrents i els sediments. La dinàmica de formació i evolució d’aquests patrons és un punt polèmic en la recerca de la dinàmica costanera. Tot sovint la zona costanera mostra una forta i persistent uniformitat longitudinal. En aquest cas, els canvis morfodinàmics són dominats pels processos transversals. Tot i que aquesta situació suposi una complexitat morfològica menor, la morfodinàmica del perfil transversal de platges és encara un repte científic, ja que, en aquest cas, el transport de sediment és el resultat d’un balanç molt subtil entre les forces onshore i offshore. L’objectiu d’aquesta tesis és obtindre una visió més clara dels processos físics involucrats en l’evolució del perfil transversal i com de importants són en la morfodinàmica costanera. Amb aquesta finalitat, s’ha desenvolupat un model morfodinàmic 1D no lineal per a l’evolució del perfil transversal per tal d’analitzar alguns aspectes importants de la morfodinàmica del perfil. El model AMORFO70 acobla la hidrodinàmica, el transport de sediments i els canvis de fons per tal de tenir en compte el feedback morfodinàmic. El model compta amb les equacions de conservació de massa i de moment integrades en el temps i en la vertical, acoblades amb les equacions de conservació d’energia de l’onatge i dels rollers, la llei d’Snell i la relació de dispersió tot suposant uniformitat longitudinal. Els processos entre-ona, i en particular la velocitat i l’acceleració orbitals a prop del fons, poden conduir al transport de sediments cap a terra. El model compta amb una nova parametrització de la velocitat a prop del fons per tal d’analitzar l’efecte de la distribució temporal de les velocitats i acceleracions a prop del fons en la morfodinàmica del perfil. S’ha provat que comptar amb l’skewness de la velocitat i de l’acceleració en el càlcul del transport és essencial per simular correctament la migració cap a terra de les barres de sorra i de l’evolució de tot el perfil. Els resultats mostren una forta dependència espacial del transport al llarg del perfil, de tal manera que a la zona de shoaling el transport és induït per esforços tallants (skewness de velocitats) i que la zona de rompents i de surf està dominada pels gradients de pressió (skewness d’acceleracions). La descripció precisa del transport de sediments és clau en la modelització morfodinàmica. El model inclou múltiples fórmules del transport per tal d’analitzar les diferències en les prediccions morfodinàmiques de cadascuna d’elles per diferents seqüències. Els resultats evidencien moltes diferències entre els valors de transport i també entre els canvis de fons incipients predits per les diferents fórmules. S’ha provat que les prediccions de l’evolució del perfil de penen de la formula de transport emprada i que aquestes prediccions no sempre segueixen les tendències esperades. En particular, les fórmules que compten directament amb el efectes de l’skewness de la velocitat i de l’acceleració donen les millors prediccions, especialment en les seqüències acrecionals. En la modelització de la morfodinamica del perfil transversal és una practica comuna el no considerar la variabilitat longitudinal. Aquest supòsit ha estat analitzat per a la predicció a curt, mig i llarg termini de l’evolució del perfil mig. S’ha demostrat que el model és capaç de predir acuradament l’evolució a curt i mig termini. El fet de considerar el perfil mig com el promig de les evolucions de diferents perfils al llarg de la costa porta als millors resultats, ja que es ’una manera de tenir en compte la variabilitat longitudinal’. A llarg termini s’ha provat que, tot i que les prediccions poden concordar amb les mesures, no capturen la morfodinamica real. Aquest fet destaca la importància de l’anàlisi de la morfodinàmica simulada durant les evolucions a llarg termini per tal d’evitar errors en la interpretació dels resultats.

Testo completoAbstract (sommario):
Using monthly beach profile surveys and historical aerial photographs, the seasonal and long-term (48 year) beach morphology for Kaanapali Beach, Maui is described. By identifying the shoreline position in historical aerial photographs it is determined that the Kaanapali area is subject to long periods of mild erosion and accretion punctuated by severe erosional events related to short-period Kona storms and hurricane waves. Increased Central Pacific tropical cyclone activity of the late 1950's and early 1960's and Hurricane Iniki in 1992 are identified as contributing factors to the observed volume change during these periods. Between these erosional periods the Kaanapali shoreline is relatively stable characterized by light erosion to moderate accretion suggesting the recovery time may be on the order of roughly 20 years. Over the 48-year period 1949 to 1997, the Kaanapali and Honokowai cells have experienced a net sediment volume loss of 43,000 ±730 m3 and 30,700 ±630 m3 respectively for a total net volume loss of 73,700 ± 990 m3. The Kona storms and hurricanes of the early 1960's and 1992 collectively account for 136,000 m3 of sediment lost or approximately 62% of the gross volume change for the entire period, revealing the significant erosional effect of these storms. Recovery after each of these storms accounts for 73,900 m3 or approximately 33% of the gross volume change. A residual loss of 10,600 m3 representing 5% of the gross volume change is inferred as chronic erosion and may be a product of relative sea-level rise (RSLR). An increase in short-period southwesterly wave energy during these erosional periods is well documented and may have transported beach sediment further offshore than normal (beyond the reef) and is identified as a possible mechanism for long-term erosion in this area. The spatial distribution of historical shoreline movement suggests the majority of sediment transport occurs in the central portion of Kaanapali near Kekaa and Hanakoo Point and is driven by longshore rather than cross-shore transport. Surveyed beach profiles reveal a strong seasonal variability with net erosion in the summer and accretion in the winter with an along the shore-alternating pattern of erosion and accretion. 65% of the net volume change occurs south of Kekaa Point confirming the more dynamic nature of the southern (Kaanapali Cell). Net beach profile volume change from the mean suggests that June and January are the most dynamic months each with approximately 14% of the total volume change. We attribute the significant and rapid erosion and accretion events due to wave-induced longshore transport of sediment. Field observations of monthly beach sediment impoundment in the Kaanapali cell are examined and compared to three models that predict longshore sediment transport (LST). Beach profile results indicate sediment impoundment occurs seasonally with a nearly balanced longshore sediment transport system between profile 5 and 9. Longshore transport rates are derived from seasonal cumulative net volume change in the middle of Kaanapali Beach at profile 7. Cumulative net sediment transport rates are 29,379 m3/yr ±15% to the north and 22,358 m3/yr ± 6% to the south for summer and winter respectively, a net annual rate of 7,021 m3/yr ± 10% to the north and a gross annual rate of 51,736 m3/yr ± 2%. Predictive transport formulas such as CERC (1984), CERC (1991) and Kamphius (1991) predict net annual transport rates at 3 x 103 percent, 77 percent and 6 x 103 percent of the observed transport rates respectively. The presence of fringing reef significantly effects the ability of the LST models to accurately predict sediment transport. When applying the CERC (1984, 1991) and Kamphius (1991) formulas, the functional beach profile area available for sediment transport is assumed much larger than actually exists in Kaanapali because of the presence of a fringing reef that truncates a portion of the sandy profile area. The CERC (1984, 1991) and Kamphius (1991) formulas don't account for the presence of a reef system which may contribute to the models overestimate of longshore sediment transport as they assume the entire profile is mobile sediment. However the fact that the CERC (1991) model underestimates the observed transport implies that additional environmental parameters (such as wave height, direction and period) playa more substantial role than the influence of the reef in the model results. The CERC (1991) Genesis model is found to be superior in fitting the observed longshore transport at Kaanapali Beach. The success of the Genesis model is partly attributed to its' ability to account for short-term changes in near-shore parameters such as wave shoaling, refraction, bathymetry, antecedent conditions and several other shore face parameters not accounted for in the CERC (1984) or Kamphius (1991) formulas. The use of the CERC (1984) formula is prone to practical errors in its' application particularly in the use of the recommended "K" coefficient and wave averaging that may a significantly overestimate the LST. A better fit to the observed LST is achieved with the CERC (1984) if the K value is decreased by an order of magnitude from 0.77 to 0.07. The Kamphius (1991) formula is especially sensitive to extremes in wave period and tends to deviate from observed transport estimates for unusually high wave periods (this study) and approximates observations nicely in areas with low wave periods (Ping Wang et al. (1998). Many of the studied predictive LST formulas are prone to overestimate transport and thus their use requires a comprehensive understanding of the complexities and errors associated with employing them. Great care must be used when applying LST models in areas with significant hard bottom or shallow reefs that alter the beach profile shape. Due to these errors, the use of the CERC (1984) and Kamphius (1991) formulas are better suited as a qualitative interpretative tool of transport direction rather than magnitude.ix, 62 leaves

Testo completoAbstract (sommario):
Beach cusps are swash zone morphological patterns that have been of interest to many scientists and engineers. This study aims to improve understanding of the formation and long-term evolution of beach cusps by numerical simulation using a 2D process-based morphodynamic model, solving the coupled NLSW equations and sediment conservation equation simultaneously. A numerical implementation is applied building on the model of Dodd et al. (2008), which succeeds in simulating the occurrence of beach cusps. The numerical scheme improves the accuracy and stability of the swash zone computation. Results from a comparison between different numerical implementations concludes that the most suitable numerical scheme is the Roe-averaged scheme of Castro Diaz et al. (2008) with Minmod flux-limiter using the Harten and Hyman (1983) entropy fix method and the Hubbard and Dodd (2002) approach for the shoreline boundary condition. Before simulating the 2D beach cusps, the sensitivity of the model parameters and two different types of incoming waves are tested in the ID bed change. The sensitivity test results show that there is a convergence of the results when the minimum computational depth (dtol) ≤ 1 mm. Also the relationship between the bed profile and beach cusp parameters is that a greater maximum tip position (xs,max) is achieved, and more erosion in the tip region occurs when the bed friction coefficient (ƒw), the hydraulic conductivity (K), and dtol are smaller. On the other hand, the effect of scaling the sediment transport coefficient (A) is to scale the rate of change of the bed level, and appears not to lead to qualitative differences. Moreover, the incoming sine wave creates three components of 1D beach profile (long-shore bar, trough, and swash berm) in the computational domain, while the incoming sawtooth wave creates a wider equivalent region, because of wave simply breaking farther offshore. The 2D simulations give approximately the same beach cusp formation as those of Dodd et al. (2008); however, the geometrical parameters (ƒ) from the self-organisation theory are still high when compared with previous field observation and numerical simulations. The evolution of the beach cusps is investigated by Fourier and global analyses (Garnier et al., 2006), and can be divided into three stages: 1D development in the cross-shore profile, 2D small cusp spacing pattern, and 2D final bigger cusp spacing pattern, caused by the coalescing of two small bays and subsequent rearrangement to an equal spacing. However, an unphysical behaviour is found during cusp evolution, which is the reversing behaviour between horn and embayment. It appears that this reversible behaviour is caused by deposition at the embayment head, created from high infiltration and the usage of the velocity-only type of sediment transport equation in the model.

Testo completoAbstract (sommario):
Coarse-grained beaches are particularly prevalent in the UK, composed of accumulations of either gravel, or mixed sand and gravel sediments. The aim of the work presented in this thesis is to improve capabilities for predicting coarse-grained beach 2D profile development. In particular, the effects of infiltration and sediment sorting are considered. In this study, the public domain numerical model, XBeach (v12) is developed further. This model was initially developed for studying sandy environments especially for the case of dune erosion. Here, the model is modified to enhance its capability to predict beach profile change on coarse-grained beaches. Improvements include: use of Lagrangian interpretation of velocity in place of Eulerian for driving sediment movement; introduction of a new morphological module based upon Soulsby’s sediment transport equation for waves and currents; incorporation of Packwood’s infiltration approach in the unsaturated area of the swash region; and implementation of a multiple sediment fraction algorithm for sediment sorting of mixed sediments. These changes are suggested and justified in order to significantly improve the application of this model to gravel and mixed beaches, especially with regard to swash velocity asymmetry which is responsible for development of the steep accretionary phase steep berm above waterline and sediment sorting. A comparison between model simulation and large scale experiments is presented with particular regard to the tendency for onshore transport and profile steepening during calm conditions; offshore transport and profile flattening during storm conditions; and sediment sorting in the swash zone. Data used for this and the model calibration comes from the Large Wave Channel (GWK) of the Coastal Research Centre (FZK) in Hannover, Germany. The results are found to agree well with the measured experimental data on gravel beach profile evolution. This is due to the inclusion of infiltration in the model which weakens the backwash volume and velocity in a more satisfying manner than through the use of asymmetric swash friction and transport coefficient. The model also simulates sediment sorting of a mixed sediment beach. However, the profile comparisons were not satisfactory due to limitations of the numerical model such as the constant permeability rate used throughout the simulation and the non-conservation of the sediment volume in the laboratory data by an order of 50%. From the simulation, it was found that the fine sediment moves offshore and the coarser sediment moves onshore. This is because of infiltration weakens the backwash velocity; the coarser sediment moving onshore barely moves back offshore while the fine sediment remains in motion. This pattern agrees with the pattern obtained from sediment samples analysis in the experiment and provides an explanation for the existence of composite beaches. The model is also shown to be capable of switching from accretionary to erosive conditions as the wave conditions become more storm-like. Again, the model simulations were in a good agreement with the observations from the GWK dataset. Numerical model simulations on the effects of the tidal cycle on coarse-grained beach profile evolution were also carried out. This preliminary investigation showed that the model was able to predict the anticipated profile change associated with a coarse-grained beach under such wave and tidal forcing. Tidally forced accretion and erosion were compared with those predicted under similar beach sediments and wave conditions for constant water level. The main differences are that the affected area is wider and the berm is located on the upper beach during flood for both gravel and mixed beaches. Therefore, the model developed in this study can be seen to be a robust tool with which to investigate cross-shore beach profile change on coarse-grained beaches and sediment sorting on mixed beaches. Further work is also indicated.

Approved for public release; distribution is unlimited.The objective of this dissertation is to develop numerical models and compare their predictions with data acquired during the DUCK94 experiment in order to improve our physical understanding of the hydrodynamic processes governing the vertical and cross shore distributions of both longshore and cross shore currents over a barred beach. The vertical structure of the mean longshore current is found to be well described by a logarithmic profile and a relationship between bed shear stress and bottom roughness, including the influence of ripples and mega-ripples, was also found. The vertical structure of the mean cross shore current (undertow) is modeled using an eddy viscosity closure scheme to solve for the turbulent shear stress and includes contributions from breaking wave rollers. These models of the vertical profiles of longshore and cross shore mean currents are combined to formulate a quasi three dimensional model to describe the cross shore distribution of the longshore current. This model includes turbulent mixing due to the cross shore advection of mean momentum of the longshore current by the mean cross shore current and contributions from wave rollers

Testo completoAbstract (sommario):
The establishment of six shingle-beaches species( Crambem aritima (sea-kale),E ryngium maritimum (sea-holly), Glauciumflavum (yellow homed-poppy), Honckenya peploides (sea sandwort), Lathyrusjaponicus (sea pea) and Rumex crispus (curled dock)) was investigated to mitigate the disturbance caused by the construction of a power station at Sizewell, Suffolk, UK. The potential for creating vegetation from container-grown plants, sown seed or the soil seed bank was examined. Shingle-beach vegetation comprising these species was successfully established using container-grown plants, whereas seeding shingle beach areas was generally unsuccessful. Mature container-grown plants were able to survive erosion or accretion, at least to some extent, because they possessed extensive root or rhizome systems which provided sufficient resources for subterranean growth, while seedlings had only a limited capacity to elongate to the new beach surface after inundation. Hernicryptophyte species were most successful in surviving disturbance; Honckenya peploides recovered from up to 0.41 m accretion or 0.26 m erosion. The monocarpic chamaephyte species, Glauciuniflavum, showed poor survival after disturbance, but successfully established from seed within one season. Seedling emergence techniques showed that there was a very limited germinable soil seed bank in June on the shingle beach compared to the neighbouring dune grassland. The seed bank was not likely to provide an adequate source of propagules for vegetation restoration. Innate hard-seed dormancy mechanisms were important in five of the six species. Dormancy reduced the potential for rapid field-establishment from seed. The use of seed stored at low temperature and humidity for 5 years showed that germination of seed, of apparently high viability, but of low vigour, was reduced because of sensitivity to non-optimal temperatures, inappropriate light conditions or low salinity concentrations. Seed germination of all species was totally inhibited by 50-100% sea-water. The establishment of vegetation was significantly influence by beach substrate composition which affected the survival, growth and fecundity of container-grown plants and seedlings emergence, survival and growth in sown plots. A mixture of shingle and sand allowed significantly greater growth in Crambe maritima, Rumex crispus and Glauciumflavum plants compared to almost pure sand substrates.

Testo completoAbstract (sommario):
Venice Beach, CA is a vibrant city with a very interesting history. The way the city sits today is much different than the way Mr. Kinney designed it in the early 1900s. Venice Beach was originally supposed to be a Venice similar to the Italian city in California. The original city had canals, a miniature railroad and eventually amusement attractions.
The purpose of re-designing Venice Beach was to bring historical value back to the city that it has lost over the years, as well as create more community centered areas and efficiency for tourists. After analyzing both visual and quantitative data, I created a problem statement which defined the four-fold problem thusly: tourists are present in all parts of town, lack of/poorly planned parking causes major problems, the city has lost some of its historical roots, there is a large socio-economic disparity between the rich and the homeless in the city and there is a need for a community center. The requirements for the project were then defined as: (1) Shall make parking more available. (2) Shall restore the historical properties of the city by adding more publicly visible canal(s) (3) Shall make new parking areas within 5 minutes of a walk to the new canal(s) (4) Shall create a sanctuary for the homeless. (5) Shall create a community center (for learning and community programs).
The four alternatives for solving the problem were created as design options for this "community centered city" design. Alternative 1 created a new canal where Speedway Road is currently. Alternative 2 and 3 were an expansion of Alternative 1. Alternative 2 created bridges over the new canal as well as a new open space between North Venice Blvd and South Venice Blvd, from Pacific Way to Venice Way. Alternative 3 was a culmination of the Alt 1 and 2, plus added mixed-use buildings, as well as a homeless shelter, community center and new parking garages. The mixed-use buildings would be erected on both sides of the new canal. The homeless shelter and community center would replace some businesses and houses in the triangle between Marr St., Oxford Ave. and Washington Street. The additional parking would be created in two places, on the northeast corner of Washington Ave and Pacific Ave as well as the northeast corner of Windward Ave and Pacific Ave all the way to Westminster Park.
A Digital Logic Parameterization Weighting System Table was used for the evaluation of alternatives. The properties used for analysis were: increased tourists, capital cost, long term cost, feasibility, schedule, restoring historical value and better community involvement. The first step was to compare each property against each other in order to figure out which one should have the highest emphasis or importance to further the evaluation (creating an emphasis coefficient). After finding the emphasis coefficients, I evaluated each alternative on the properties defined in the weighting table. Then, I compared each seemingly incomparable data set to alternatives through scaling by using the maximum and minimum properties and the emphasis coefficient. The overall performance index was created by compiling the scaled properties, determining that Alternative 3 was the "best" option.
It was determined that lean methods could be used in the project construction. Also, many system engineering heuristics and lessons learned from other projects could be applied to the project. The principles of quality and verification of requirements can all be applied to the project. Many models were used to determine the activities, structure and principles of the design. Using this new design for Venice Beach could create a great future. This design would attract more tourists and provide the community with resources needed. Future work includes finding the resources to make my re-design become a reality.

Testo completoAbstract (sommario):
Over the years many studies have been completed on the carrying capacity of specific recreational activities. These studies generally focus on the factors and interactions that are limiting the growth of an area and what barriers need to be removed to allow for this growth. This study looks specifically at the perception of carrying capacity of Gold Coast beaches and the way in which they are used by tourists and locals.
For the purpose of this study the definition of Beach Carrying Capacity is the perceived number of people that can fit comfortably on a beach, including the surf zone, before adversely affecting an individual person’s beach recreation experience and/or the surrounding environment. Beach usage encompasses all activities participated along any adjacent infrastructure including parks and oceanway, sandy beach and surf zone areas including swimming, surfing, walking, sunbaking and picnicking.
During the research period a short questionnaire was produced and applied to a range of people along various Gold Coast beaches and within Griffith University. The questionnaire looked at what people used the beach for and how they perceived the crowding on the beaches. Results showed that the carrying capacity on Gold Coast beaches, by the survey respondents’ perceptions, has already been reached on some of the Gold Coast’s most popular beaches.
The study then looked at and compared the results from the Portugal study (da Silva, 2002) to those obtained on the Gold Coast. Results showed that the survey data collected from the two locations does not differ greatly. Perceptions of beach carrying capacity and the general activities people used the beach for were uniform in both study locations.
This study highlights the importance of beach monitoring as it allows us to determine what people are using the beach for and how they would like them to be used. The information obtained about how people are using the beaches will provide valuable data to coastal councils and coastal management authorities to help future beach planning and management.
Recommendations are made to enhance and continue future beach monitoring research with the use of current beach camera technology such as CoastalCOMS.Thesis (Masters)

In this study, a two-dimensional depth-averaged beach evolution numerical model is developed to study the medium and long term nearshore sea bottom evolution due to non-cohesive sediment transport under the action of wind waves only over the arbitrary land and sea topographies around existing coastal structures and formations. The developed beach evolution numerical model is composed of four sub-models: a nearshore spectral wave transformation model based on energy balance equation including random wave breaking and diffraction terms to compute the nearshore wave characteristics, a nearshore wave-induced circulation model based on the non-linear shallow water equations to compute the nearshore depth averaged wave-induced current velocities and mean water level changes, a sediment transport model to compute the local total sediment transport rates occurring under the action of wind waves and a bottom evolution model to compute the bed level changes in time due to gradients of sediment transport rates in cross-shore and longshore directions. The governing partial differential equations are solved utilizing finite difference schemes. The developed models are applied successfully to several theoretical and conceptual benchmark cases and an extensive data set of laboratory and field measurements. As an alternative approach to be used in beach evolution problems, a distributed total sediment load formula is proposed based on the assumption that the local total sediment transport rates across the surf zone are proportional to the product of the rate of dissipation of wave energies due to wave breaking and wave-induced current velocities. The proposed distribute load approach is validated with the available laboratory and field measurements.

Testo completoAbstract (sommario):
The problem of cross-shore beach face evolution in the swash zone is examined within the framework of the shallow water theory. A system comprising the shallow water and Exner equations is solved numerically using both uncoupled and fully coupled approaches. The uncoupled model assumes that changes in bed height have a negligible effect on the flow over a swash event, whereas the fully coupled model updates the hydrodynamic variables and beach profile simultaneously. In order to obtain accurate results over a single swash event several new numerical solvers based on the method of characteristics (MaC) and the MacCormack (1969) explicit finite-difference scheme are detailed. Particular attention is given to the treatment of discontinuities. A procedure for the explicit treatment of discontinuities, derived from techniques employed in gas dynamical problems, is developed and applied. Certain rather novel shock capturing approaches are also investigated. The shoreline boundary is discussed and a new robust algorithm for the treatment of this boundary on both fixed and mobile beds is presented. The resulting numerical models are used to simulate a variety of different swash events on an initially plane sloping mobile beach. Predictions of beach face evolution are made using the fully coupled approach and are compared with predictions made using an uncoupled analytical beach evolution model based on that of Pritchard and Hogg (2005). The fully coupled model leads to some interesting observations, in particular the possibility of local onshore sediment transport and the occurrence of a seaward facing sediment bore in the backwash. A characteristics based analysis is performed and reveals important differences in the flow structure of coupled and uncoupled swash events. The maximum wave run-up is also considered and it is shown that for the fully coupled system the run-up is significantly less than that predicted by the Shen and Meyer (1963) theory and motion of the leading edge can no longer be determined using simple ballistics concepts. Additionally, for verification purposes, new quasi-analytical solutions are constructed for the mobile bed dam-break problem using two distinct sediment transport formulae.

Testo completoAbstract (sommario):
Beach cusps, formed during a storm are observed. The storm acted for three hours together with high water conditions. These beach cusps exhibited a quasiuniform wavelength of 8 m. The measured topography after the storm, the calculated drift velocity of the incident wave and the synchronous edge wave are similar in scale
and shape. The over one wavelength measured grain size is also correlated to the topography.
A nonlinear hydro-numerical model is used to investigate the reaction of edge waves on alongshore change in bottom topography. Edge waves are greatly amplified over beach cusps. The relative amplification of edge waves on beach cusps is more than 17 times that without a change in longshore topography. Amplification is slightly greater for edge waves travelling in the same direction as the longshore current during the storm. An almost random positioning of sediment starts a feedback loop, which allows edge waves to grow and build short periodic cusps.

Testo completoAbstract (sommario):
Temporal and spatial changes in nearshore bathymetry result from sediment transport interactions with the hydrodynamic processes and provide a highly variable and rapidly changing environment. Rip currents are one example of a morphody- namic system presenting a significant hazard to swimmers unfamiliar with their behaviour. Rip currents pose a particular threat as they can develop suddenly and quickly transport water offshore.
The widely accepted beach state model of Wright & Short (1984) uses param- eters which are functions of breaking wave height, wave period and sediment (Dean 1973, Gourlay 1968, Guza & Inman 1975) to classify the beach environment into distinct morphological states. These states range from reflective through inter- mediate to dissipative.
Breaking wave type is influenced by the bathymetry as the wave approaches breaking point within the surf-zone and can be classified by the the Iribarren num- ber or surf-similarity parameter (Battjes 1974). Intermediate beach states can be more difficult to assess with these parameters and may even consist of a combination of outer dissipative and inner locally reflective zones.Thesis (PhD Doctorate)

Testo completoAbstract (sommario):
Questa tesi dal titolo "Approcci della scienza dei cittadini per il monitoraggio dei rifiuti da spiaggia" si concentra sui rifiuti marini delle spiagge (di seguito MBL). MBL rappresenta un enorme problema che riguarda le aree scientifiche, economiche e sociali. Durante il primo anno di dottorato è stata organizzata e realizzata un'attività pilota di citizen science per il monitoraggio dell'ambiente balneare con studenti delle scuole primarie e secondarie, utilizzando il protocollo MAC-Emerso. Le osservazioni raccolte sono state incluse nel database ufficiale MAC-Emerso.
Durante il secondo anno, è stata completata un'analisi bibliometrica sul MBL e i risultati raggiunti sono stati organizzati per la pubblicazione in una rivista peer-reviewed. Inoltre, è stata effettuata un'analisi preliminare del database nazionale MAC-Emerso disponibile.
Il terzo anno è stato dedicato alla compilazione di studi e programmi precedenti incentrati sul monitoraggio MBL e sulle campagne di bonifica lungo la costa mediterranea. Tutte le metodologie applicate fino ad oggi sono state analizzate e confrontate nel dettaglio per identificare i punti di forza e di debolezza dei protocolli attuali, il coinvolgimento dei cittadini e le lacune esistenti.
La presente tesi è composta da otto capitoli e due articoli e si apre con un'introduzione generale che descrive MBL (Capitolo 1). Il capitolo 2 discute l'obiettivo generale della ricerca di dottorato e riassume gli articoli inclusi nella tesi di dottorato. Il capitolo 3 esamina in dettaglio la strategia marina, mentre il capitolo 4 si concentra sulla scienza dei cittadini e sul protocollo MAC-Emerso. Il capitolo 5 descrive i principali risultati raggiunti, inclusa l'attività pilota di citizen science organizzata e realizzata per il monitoraggio dell'ambiente balneare con gli studenti delle scuole primarie e secondarie che utilizzano il protocollo MAC-Emerso. Il capitolo 6 comprende la raccolta dei due articoli scientifici su MBL realizzati durante le attività di dottorato.
Il primo paper (Cesarano et al., 2021) è stato pubblicato su Marine Pollution Bulletin (con ranking Q1), mentre il secondo paper è stato recentemente inviato alla stessa rivista. Il primo esplora la letteratura scientifica globale sull'MBL attraverso un'accurata analisi bibliometrica. Quest'ultimo presenta una revisione sistematica della letteratura corrente sul monitoraggio MBL lungo le coste del Mediterraneo. Insieme, forniscono una revisione completa delle conoscenze scientifiche sull'MBL nella regione mediterranea e offrono spunti interessanti per capire dove si trovano le lacune attuali e cosa sarebbe necessario per sviluppare un monitoraggio più efficiente su scala di bacino a sostegno dei nostri sforzi per affrontare il Sfida MBL.
Infine, un'osservazione conclusiva dei risultati complessivi raggiunti nel presente studio è elaborata nel Capitolo 7. Segue una nota sugli altri prodotti non inclusi in questa tesi, ma eseguiti durante il mio periodo di dottorato. Quindi, un elenco di riferimento degli studi menzionati attraverso la tesi conclude questo documento.This thesis entitled “Citizen Science approaches for beach litter monitoring” focuses on Marine Beach Litter (hereafter MBL). MBL represents a huge problem that concerns scientific, economic, and social areas. During the first year of my PhD, a pilot citizen science activity was organized and realized for monitoring beach environment with primary and secondary school students, using the MAC-Emerso protocol. The collected observations were included in the official MAC-Emerso database. During the second year, a bibliometric analysis on the MBL topic has been completed and the achieved results have been organized for publication in a peer-reviewed journal. Furthermore, a preliminary analysis of the available national MAC-Emerso database was carried out. The third year was devoted to compile previous studies and programs focusing on MBL monitoring and cleanup campaigns along the Mediterranean coastline. All the methodologies applied to date have been analysed and compared in detail to identify strengths and weaknesses of current protocols, citizen involvement, and existing gaps. The present thesis consists of eight chapters and two papers and opens with a general introduction describing MBL (Chapter 1). Chapter 2 discusses the overall aim of the PhD research, and summarizes the papers included in the PhD thesis. Chapter 3 examines in detail the Marine Strategy, while Chapter 4 focuses on Citizen Science and the MAC-Emerso protocol. Chapter 5 describes the main results achieved, including the pilot citizen science activity organized and realized for monitoring beach environment with primary and secondary school students using the MAC-Emerso protocol. Chapter 6 includes the collection of the two scientific papers on MBL realized during the PhD activities. The first paper (Cesarano et al., 2021) has been published in Marine Pollution Bulletin (with Q1 ranking), while the second paper has been recently submitted to the same journal. The former explores the global scientific literature on MBL through an accurate bibliometric analysis. The latter presents a systematic review of current literature concerning MBL monitoring along the Mediterranean coasts. Together, they do provide a comprehensive review of the scientific knowledge on MBL in the Mediterranean region and offer interesting insights to understand where current gaps lie, and what would be needed to develop a basin-scale more efficient monitoring in support of our efforts to tackle the MBL challenge. Finally, a concluding remark of the overall results achieved in the present study is elaborated in Chapter 7. A note about the other products not included in this thesis, but performed during my PhD period, follows. Then, a reference list of the studies mentioned through the thesis ends this document.
