Résumé :
Erosion is the dominant behavior along worldwide coastlines. Although many factors can locally influence processes governing coastline evolution some common factors can be identified. Thus, the sediment budget has largely been modified in most of developed coasts, with river sand supplies being drastically reduced due to human influence in drainage basins. On the other hand, coastal segmentation due to infrastructures alters sediment transport patterns and induces and/or accelerates coastline erosion. Within this general context, artificial nourishment has been one of the most used coastal engineering measure by mimicking the role played by river sediment supplies to compensate local erosion problems. Since nourishment is not acting on the origin of the problems, erosive processes will continue to control shoreline evolution. Thus, the evolution of beach fills will be controlled by the sediment budget within the coastal cell where works have been done and, this will determine required sediment volumes to maintain the future shoreline. Within this context, we present data on long-term (25 years) shoreline evolution and nourishment operations in the Tarragona coast (Spain, NW Mediterranean). The main aim of the work is to analyze the coastal stability and the effects of beach fills along the coast taking into account the type of the coastal cell where works have been implemented. Once this has been evaluated, the sustainability of an adaptation strategy based on the use of this protection measure to cope with climate change induced scenarios is also assessed to propose a long- term sediment management plan.

Résumé :
Coastal erosion and flooding are hazards that, when combined with facilitative pathways and vulnerable receptors, represent sources of coastal risk. Erosion and flooding risks are often analysed separately owing to complex relationships between driving processes, morphological response and risk receptors. We argue that these risks should be considered jointly and illustrate this through discussion of three ‘expressions’ of this interactive relationship: coastal morphology modifies flood hazard; future flood risk depends on changing shoreline position; and the simultaneous occurrence of erosion–flooding events. Some critical thoughts are offered on the general applicability of these expressions and the implications for coastal risk management policy.

Résumé :
Bight of Benin coast is highly vulnerable to climate change and one of its negative effects: sea level rise. It affects the coastal zones of Ghana, Togo and Benin. Within these areas, a substantial impact is expected not only on livelihoods but also on key infrastructure in coastal areas, leading to the destruction of coastal line and its habitats, socio-economic mutations and beach erosion increase. In Togo, the erosion retreat, due to improper coastal and infrastructure management, has been estimated between 5 to 10 meters per year during the period 1955-1985 and 20 to 30 meters per year during the period 1985-2009, forcing the coastal road linking Lomé to Aného to be moved twice. Taking into consideration climate change, this figure will progressively increase. Under the African Development Fund 13th cycle (2014 - 2017), the African Development Bank (AfDB) is supporting the Togolese government’s effort of strengthening regional integration through the financing of transport infrastructure, in particular the “rehabilitation of the corridor Lome-Cotonou and transport facilitation project”. The main objective of AfDB project is to finance the related infrastructure and capacity building that will make coastal infrastructure, roads in particular, climate resilient.

Résumé :
The purpose of this paper is to present the multidisciplinary approach adopted to undertake a detailed coastal flood and erosion risk management investigation at Cloughaninchy beach (Ireland). The site was severely affected by a series of extreme events with extreme high tide combined with a severe sea swell and onshore winds resulting in severe damage due to flooding and wave action as well as substantial retreat of the dune system. Based on a comprehensive assessment and multidisciplinary studies an appropriate plan was subsequently developed to best manage the risks identified and to further assess the feasibility of the recommended management plan options and measures. The project is an example of how vital the integration of specialized disciplines (coastal engineering, hydraulic flood modelling and coastal morphology) is in the determination of the appropriate protection measures for coastal sites.

Résumé :
A coastal erosion risk assessment was framed as the basis for the intervention of coastal adaptation strategies under time-variant scenarios. The framework was devised to assess the influence of coastal erosion on coastal defense, the coastal inundation induced by the erosion-induced malfunction of defense, and risks using a downscaling analysis and the mechanism of the compound hazard interaction, which are innovative and practical for the application of coastal management in Taiwan. In addition, the vulnerable socio-economy was also taken into consideration in risk assessment. The adaptive strategy is proposed in terms of the risk origins and time-variance of risk forecasts, and the risk origins were assessed based on the Fuzzy Delphi Method and the analytic hierarchy process instead of subjective consideration. Within the erosion-induced hazard and risk assessments, this study considered erosion rates, decreases in defense elevation due to land subsidence, and population development in time-variant scenario analyses to estimate risk forecasts. Furthermore, a case study of the Yunlin coastal area was undertaken to demonstrate the feasibility of the proposed method. The presented results are informative for coastal hazard reduction and the promotion of the sustainable development of coastal zones.

Résumé :
This paper presents the outcome of a coastal engineering hydro and morpho-dynamic model study using a number of numerical models which was conducted by the author on the erosion state of the Mediterranean coast of Israel for a time horizon of 100 years. The study assessed future sea levels, and compared wave setup and runup and beach profile erosion at the coastal cliffs in order to determine the relative sensitivity of the various coastal sectors of the Israeli shore. Finally it investigated measures and means for effective the mitigation of the forecasted beach and cliff erosion. The study was carried out as part of a multi disciplinary work involving various additional disciplines, and was used to establish a national policy document in regards to the coastal cliffs collapse and erosion by natural and anthropogenic induced factors, including global warming induced sea level rise and reduced return period of extreme events. The approach and outcomes are estimated to be useful for coasts of similar conditions elsewhere on the globe.

Résumé :
Monitoring on coastal erosion problems along the São Paulo shoreline have been carrying out by the author since mid the 80’s, including almost 87% of the whole 430 km length of sandy beaches. Eleven types of indicators of coastal erosional processes have been recognized, which have been attributed to seventeen causes, among them ten correspond to natural mechanisms and seven are due to anthropogenic interference. In this paper is presented rates of shoreline retreat based on the Bruun Rule application for six of the most threatened beaches, for a period as long as 56 years. Risk assessment is also estimated for these six beaches based on two criteria: (i) the total number (sum) of types of coastal erosion indicators found along the shoreline (frequency among the 11 types) and (ii) general spatial distribution (percentage of surface area) of coastal erosion indicators along the shoreline. Causes and effects of the coastal erosional processes are discussed for these six beaches. Results reveal high rates of shoreline retreat, even in non-urbanized areas, as well demonstrate that the six beaches are at very-high risk. Moreover, they indicate that natural mechanisms are very important as cause of coastal erosional processes in São Paulo, sometimes most them the human-induced causes. These studies have widely been supporting the State Plan for Coastal Zone Management, in order to create special rules for occupation and some activities along the shoreline, including engineering works, building and sand beach exploration. Besides, results are being recorded in a geoenvironmental information system for the Coastal Zone of the State of São Paulo (Project SIIGAL), which is in phases of implantation.

Résumé :
Economic and population growth have led to an unprecedented increase in the value at risk in coastal zones over the last century. To avoid excessive future losses, particularly in the light of projected climate change impacts, coastal zone managers have various instruments at their disposal. These primarily concern land-use planning (establishing buffer zones) and engineering solutions (beach nourishment and coastal protection). In this paper, we focus on risk mitigation through the implementation of buffer zones (setback lines). Foregoing land-use opportunities in coastal regions and protecting coasts is costly, but so is damage caused by inundation and storm erosion. Defining appropriate setback lines for land-use planning purposes is a balancing act. It is however unclear what level of protection is facilitated by current approaches for defining setback lines, and whether this is, at least from an economic perspective, sufficient. In this paper, we present an economic model to determine which setback lines would be optimal from an economic perspective. The results provide a useful reference point in the political debate about the acceptability of risk in coastal zones. The main conclusions are (i) that it is useful to define setback lines on the basis of their exceedance probabilities, (ii) that the exceedance probability of an economically efficient setback line will typically be in the order of magnitude of 1/100 per year, (iii) that it is important to distinguish between situations in which morphological conditions are stationary and non-stationary, and (iv) that long-term uncertainties (e.g. due to climate change) influence the exceedance probability of efficient setback lines but only to a limited extent.

Résumé :
Climate change is causing serious threats on natural and human systems worldwide. In particular, climate-related impacts will be especially relevant in coastal areas, where a dense interaction between terrestrial and marine systems occur. Located at the land-sea interface, coastal areas, are dynamic environments where natural and anthropogenic forcing interact at diverse temporal and spatial scales modifying their geomorphological, physical and biological characteristics. Against this complex interplay, coastal managers and policy makers are increasingly asking for new integrated approaches supporting a multi-scenario analysis of environmental risks arising from natural and anthropic stressors. In the frame of this thesis, a GIS-based Bayesian Network (BN) approach was developed, exploiting functionalities offered by both methods to evaluate the probability (and related uncertainty) of coastal erosion risks, and connected water quality variation, against multiple ‘what-if’ scenarios, including different climate conditions (e.g. sea level rise). Resulting output of its application to the testing case of the shoreline of the municipality of Ugento (Apulia Region, Italy), represents valuable information to support robust decision-making and to provide the means for adaptive policy pathways in the context ICZM implementation and disaster risk reduction.

Résumé :
The main goal of this work is to provide a regional assessment of the coastal vulnerability of Sardinian sandy beaches to storm impacts. To do this we have assessed the geomorphic coastal vulnerability taking into account the intensity of storm induced hazards and the adaptation capacity of the system. The methodology aplied allows to calculate quantitatively -in a separate manner- the erosion and inundation hazards induced by the storms associated to a given probability of occurrence. The practical application of this method is to provide information that allows stakeholders to manage resource allocation and mitigate consequences. This framework has been developed by covering the following steps:(i). Define forcing conditions for the Sardinian coast using a storm classification method; to obtain this we have divided the Sardinian coast in 4 different sectors. For each sector storm events have been defined from hindcast wave data obtained for the period between 1979-2012. (ii) Find out the induced beach response to each storm class measured by the quantification of the flooding and erosion hazards. In each sector sandy beaches have been characterized in terms of their slope, height, widht and grain size. (iii) Estimation of a coastal vulnerability index formulated in terms of these two intermediate variables by means of a linear function that ranges from a minimum value of 0 (optimum state) to a maximum of 1 (failure state), defining 5 qualitative categories (Very Low, Low,. Medium, High, Very High). (iv) Assessment and mapping of the coastal vulnerability index along different sectors of the island. In terms of prospective analysis we have built a projected timeline of beach hazard based on existing storm data fitted into an extreme probability function. Once the probability of occurrence of the flooding and erosion hazards has been assessed and a risk level defined by the stakeholders, the spatial distribution of vulnerabilities associated to selected probability level will permit to "robustly" compare areas along the coast to identify the most endangered zones.

Résumé :
The geography of Scotland, with a highly undulating hinterland, long and indented coastline, together with a large number of islands, means that much social and economic activity is largely located at the coast. The importance of the coast is further highlighted by the large number of ecosystem services derived from the coast. The threat posed by climate change, particularly current and future sea level rise, is of considerable concern and the associated coastal erosion and coastal flooding has the potential to have a substantial effect on the socioeconomic activity of the whole country. Currently, the knowledge base of coastal erosion is poor, which serves to hinder the current and future management of the coast. This research reported here aimed to establish four key aspects of coastal erosion within Scotland: the physical susceptibility of the coast to erosion; the assets exposed to coastal erosion; the vulnerability of communities to coastal erosion; and the coastal erosion risk to those communities. Coastal erosion susceptibility was modelled here within a GIS, using data for ground elevation, rockhead elevation, wave exposure and proximity to the open coast. Combining these data produced the Underlying Physical Susceptibility Model (UPSM), in the form of a 50 m2 raster of national coverage. The Coastal Erosion Susceptibility Model (CESM) was produced with the addition of sediment supply and coastal defence data, which then moderates the outputs of the UPSM. Asset data for dwellings, key assets, transport infrastructure, historic assets, and natural assets were used along with the UPSM and CESM to assess their degree of exposure to coastal erosion. A Coastal Erosion Vulnerability Model (CEVM) was produced using Experian Mosaic Scotland (a geodemographic classification which identifies 44 different social groups within Scotland) to classify populations based upon 11 vulnerability variables. Dwellings were assigned a CESM and CEVM score in order to establish their coastal erosion risk. This research demonstrated that the issue of coastal erosion will impact on a relatively low number of properties compared to those impacted by flooding (both coastal and fluvial) as many dwellings are already protected by coastal defences. There is therefore, a considerable future liability, and great pressure for coastal defences to be maintained and upgraded in their current form. The use of the CEVM is a novel inclusion within a coastal erosion assessment for Scotland. Use of the CEVM established that coastal erosion risk is not distributed equally amongst the Scottish coastal population and highlighted that risk can be reduced by either reducing exposure or reducing vulnerability. Thus far in Scotland, reducing exposure has been the primary management approach, which has a number of implications with regards social justice. This research identified the existing data gaps that should be addressed by future research in order to further improve coastal management in Scotland. Future research should focus on assessing historical coastal change rates on a national scale, improve modelling of national scale wave exposure, enhance the information held about current coastal defences and, determine the direct and indirect economic cost associated with the loss of different asset types. It is also necessary to clarify the social justice implications of using adaptation approaches to manage coastal erosion as well as establishing a method to communicate the susceptibility, exposure, vulnerability and risk aspects whilst minimising the potential negative impacts (e.g. property blight) of releasing such information.

Résumé :
L’enjeu de cette étude est d’analyser comment le risque d’érosion côtière est appréhendé d’un point de vue juridique. Ce risque naturel se caractérise par une avancée progressive de la mer sur les terres, appelée à s’accentuer dans les prochaines décennies selon les derniers rapports scientifiques. Cependant, l’on observe que parallèlement à cela, les côtes métropolitaines accueillent une population de plus en plus grandissante ; se produit ainsi la rencontre de deux tendances antinomiques. Dès lors, l’objet de la présente étude est d’observer les conséquences juridiques résultant de cette confrontation. Par conséquent, afin de parvenir à la conciliation de ces différents enjeux, nous allons démontrer l’intérêt de faire évoluer les politiques publiques de gestion de l’érosion côtière en faveur d’une approche intégrée, selon les principes fondamentaux de la GIZC. Notre étude va ainsi proposer une traduction juridique de cette évolution
The aim of this study is to analyze how the risk of coastal erosion is apprehended at a legal point of view. This natural risk is characterized by a gradual encroachment of the sea on land, intending to grow in the coming decades according to the latest scientific reports. However, it is observed that beside this, the metropolitan coast are home to an increasingly growing population ; so we find the meeting of two contradictory trends. Therefore, the purpose of this study is to observe the legal consequences of this confrontation. So, in order to achieve the reconciliation of these issues, we will demonstrate the importance of the development of public policies for managing coastal erosion in favor of an integrated approach, based on fundamental principles of ICZM. Our study will thus provide a legal expression of this development

Texte intégral
Résumé :
L’érosion des falaises meubles résulte de la dénudation progressive des formations superficielles héritées recouvrant les littoraux actuels. Leur recul est irrégulier et souvent plus modéré que le recul des littoraux d’accumulation. Ce type de falaise s’étend, en Bretagne, sur 20 % du linéaire côtier. Malgré une dynamique encore mal cernée, l’urbanisation et les activités humaines se sont densifiés à leur sommet et en arrière des versants au cours des dernières décennies. Leur érosion est donc étudiée dans cette thèse sous l’angle des risques côtiers générés par l’occupation actuelle des versants des falaises meubles régionales. L’analyse porte sur l’aléa, les enjeux exposés et la gestion afin d’évaluer le risque d’érosion et d’approcher la vulnérabilité de ces territoires.L’approche systémique vise, par emboitement d’échelles temporelles et spatiales, à identifier les composantes contribuant à augmenter la vulnérabilité de ces littoraux.Une chronique d’aléas sur les 20e et 21e siècles présente la répartition spatio-temporelle régionale de l’érosion et les facteurs générateurs. Sur six sites d’étude représentatifs, la photo-interprétation (entre 1950 et 2015) et un suivi photogrammétrique (de 2017 à 2019) quantifient les vitesses et les rythmes de recul des falaises meubles. La cartographie géomorphologique aboutit à un nouveau paradigme pour l’évaluation du risque d’érosion de ces littoraux. Enfin, des indicateurs d’enjeux et de gestion déterminent la vulnérabilité sur ces sites et une enquête régionale menée auprès des acteurs institutionnels identifie les dispositifs de gestion absents. Selon leur typologie, les falaises meubles sont diversement exposées à une érosion favorisée par les facteurs météo-marins combinés, incluant notamment les précipitations. En Bretagne, leur recul menace surtout des terrains résidentiels et agricoles. Les indicateurs de vulnérabilité mettent en évidence l’insuffisance des documents réglementaires, de stratégies locales, de concertation et de sensibilisation des citoyens. Ils permettent de mieux comprendre les difficultés posées par la gestion du risque d’érosion
The erosion of soft cliffs results from the denudation of inherited, superficial formations covering the current coastlines. Their retreat rate is unsteady and often smaller than on accumulation coasts. This type of cliffs represents, in Brittany, 20 % of the coastline. Although their evolution is not fully understood, urbanization and human activities have grown denser at the top of these soft cliffs and behind, in recent decades. This thesis addresses coastal erosion with a focus on coastal risks induced by current urbanization of these soft cliffs at regional scale. The analysis tackles the hazard, stakes and management components in order to assess erosion risk and to draw near the vulnerability of these territories.A systemic approach is adopted, nesting temporal and spatial scales, with the objective to identify the components contributing to the vulnerability of these coastal territories.A chronicle of erosion events at regional scale is produced to present the spatio-temporal distribution of erosion over the 20th and 21st centuries and to analyze the generating factors.Focusing on six representative sites, aerial photographs (between 1950 and 2015) and photogrammetric monitoring (from 2017 to 2019) allow a quantitative study of the kinematics of soft cliffs retreat. A new paradigm for assessing and mapping the erosion risk for soft cliffs is proposed.Finally, indicators for stakes and risk management allow assessing vulnerability at these sites, and a survey conducted among regional stakeholders identifies gaps in risk management policies. According to their type, soft cliffs show a range of erosion responses, controlled by a combination of subaerial and marine factors, including rainfall. In Brittany, their retreat threatens mainly residential and agricultural lands. The vulnerability indicators highlight the paucity of regulations, local management strategies, dialogue and public awareness. They allow a better understanding of the challenges raised by risk erosion management

Résumé :
This study shows the link connecting natural and cultural goods in the coastal landscape of Calabria (Southern Italy), considering seaboard and human impact risk conditions. In fact, Calabria has 58 Natura 2000 sites located on seaboard areas within a length of 300 meters from coast and 63 cultural heritage sites of which 42.9% coincides with the Natura 2000 network. As a results of this paper, the increasing coastal erosion and a heavy human impact have been highlighted as the main hazards to which the natural and cultural goods are exposed, thus it’s necessary a broader approach for the integration of natural and cultural issues into an active Integrated Coastal Zone Management process

Résumé :
The UK Low Level Waste Repository Ltd submitted an Environmental Safety Case for the disposal of low-level waste to our regulator, the Environment Agency, on the 1st of May 2011. This includes assessments of the long-term radiological safety of past and future disposals. A particular feature of the Low Level Waste Repository (LLWR) is that, because of its proximity to the coast, the site is vulnerable to coastal erosion. Our present understanding is that the site will be eroded on a timescale of a few hundred to a few thousand years, with consequent disruption of the repository, and dispersal of the wastes. We have undertaken a programme of scientific research and monitoring to characterise the evolution and function of the current coastal system that provides a basis for forecasting its future evolution. This has included modelling of contemporary hydrodynamics, geomorphological mapping, repeat LiDAR and aerial photographic surveys to detect patterns and rates of change, coastal inspections and reconstructions of post-glacial (i.e. last 15,000 years) sea levels and sediment budgets. Estimates of future sea-level rise have been derived from international sources and consideration given to the impact of such on the local coastline. Two alternative models of coastal recession have then been applied, one empirical and one physical-process based, taking account of the composition of Quaternary-age sediments between the coast and the site and uncertainties in future local sea level change. Comparison of the ranges of calculated times to site contact with sea-level rise indicate that the repository is most likely to be disrupted by undercutting of the engineered vaults and of the trenches. A novel and flexible radiological assessment model has been developed to analyse the impacts of the erosion of the repository and subsequent dispersal of wastes. The model represents the spatial layout of the site and distribution of radionuclides within the repository and is able to take account of a range of uncertainties. These include uncertainties related to the rate of erosion through the facility, amounts of co-erosion of geological and cap materials, alternative assumptions for residence of waste materials on the beach, alternative waste form associations, the wider dispersion of the eroded materials and marine sorption/desorption processes. Results indicate assessed annual doses and risks that are consistent with regulatory guidance levels.

Résumé :
High-speed railway "Moscow-Kazan" by the draft crosses the Volga (Kuibyshev reservoir) in Chuvashia region 500 m below the village of New Kushnikovo. The crossing plot is a right-bank landslide slope with a stepped surface. Its height is 80 m; the slope steepness -15-16o. The authors should assess the risk of landslides and recommend anti-landslide measures to ensure the safety of the future bridge. For this landslide factors have been analyzed, slope stability assessment has been performed and recommendations have been suggested. The role of the following factors have been analyzed: 1) hydrologic - erosion and abrasion reservoir and runoff role; 2) lithologyc (the presence of Urzhum and Northern Dvina horizons of plastically deformable rocks, displacement areas); 3) hydrogeological (the role of perched, ground and interstratal water); 4) geomorphological (presence of the elemental composition of sliding systems and their structure in the relief); 5) exogeodynamic (cycles and stages of landslide systems development, mechanisms and relationship between landslide tiers of different generations and blocks contained in tiers). As a result 6-7 computational models at each of the three engineering-geological sections were made. The stability was evaluated by the method “of the leaning slope”. It is proved that the slope is in a very stable state and requires the following measures: 1) unloading (truncation) of active heads blocks of landslide tiers) and the edge of the plateau, 2) regulation of the surface and groundwater flow, 3) concrete dam, if necessary.

Cheboksary reservoir impact to the coast is manifested in the geophysical impact associated with abrasion activities. Geomorphological area of influence at the moment reaches a width of about 40 m, where are the coasts reformation (erosion, collapse, slumping, sliding, transfer or accumulation of sediments, waterlogged processes). Hydrogeological impact is effect on the level of groundwater. We have proposed the conceptual foundations of functional zoning of the reservoir banks that will help to optimize its operation. Selection zones came in accordance with the principles of landscape planning: 1. The zone of strict water protection: the main purpose – preservation of needing special protection areas. 2. The zone of moderate restrictions: preservation extensively used landscapes. 3. The zone of partial restrictions: improving the pre-emptive particularly vulnerable areas and changing intensity or type of use. 4. The zone of conservation of natural components in agricultural landscapes: ensuring health of the natural environment in the habitats used in agricultural economy. 5. The zone of preservation of vacant space and the natural environment in the settlements: to maintain the required quantity and quality of available green space in the large towns. 6. The zone of improving heavily used areas: elimination of harmful stress and environmental sanitation in the countryside where economic activities and the lack of measures to reduce their risks lead to degradation natural system.

Résumé :
The US Army Corps of Engineers (USACE) is conducting the “South Shore of Long Island, New York Regional Sediment Management Investigation” to further understand sediment dynamics and to develop a comprehensive regional sediment management plan for the south shore of Long Island, New York. Regional sediment management is a systems approach using best management practices for more efficient and effective use of sediments in coastal, estuarine, and inland environments. This investigation seeks to characterize sediment movement on the south shore of Long Island as a holistic system across the entire study area. It focuses on the regional system post-Hurricane Sandy (October 2012) as the storm significantly altered the physical landscape with severe shoreline erosion, which resulted in the construction of projects to reduce the risk of future storms and stakeholder priorities with a new emphasis on bay-side sediment dynamics, such as channel shoaling and disappearing wetlands. Despite the fact the storm caused severe erosion, the equilibrium beach profile, depth of closure, and general shoreline orientation seem to be unaffected. Previous studies have characterized sediment movement at specific sections of the south shore, but these data have not been incorporated to create a system-wide perspective. Coordinating sediment management across the six Atlantic Ocean inlets, Great South Bay Channel, Intracoastal Waterway, and coastal storm risk management (CSRM) projects could save the federal government millions of dollars in dredging and sand placement actions. This technical note presents the progress the investigation has made to date and will be followed with a more in-depth technical report titled South Shore of Long Island, New York Regional Sediment Management Investigation: A Post-Hurricane Sandy Shoreline Evaluation, currently in preparation.

Résumé :
The US Army Corps of Engineers, Galveston District, is executing the Coastal Texas Protection and Restoration Feasibility Study coastal storm risk management (CSRM) project for the region. The project is currently in the feasibility phase. The primary goal is to develop CSRM measures that maximize national net economic development benefits. This report documents the coastal storm water level and wave hazard, including sea level rise, for a variety of flood risk management alternatives. Four beach restoration alternatives for Galveston Island and Bolivar peninsula were evaluated. Suites of synthetic tropical and historical non-tropical storms were developed and modeled. The CSTORM coupled surge-and-wave modeling system was used to accurately characterize storm circulation, water level, and wave hazards using new model meshes developed from high-resolution land and sub-aqueous surveys for with- and without-project scenarios. Beach morphology stochastic response was modeled with a Monte Carlo life-cycle simulation approach using the CSHORE morphological evolution numerical model embedded in the StormSim stochastic modeling system. Morphological and hydrodynamic response were primarily characterized with probability distributions of the number of rehabilitations and overflow.

Résumé :
The 2017 Duck Unmanned Aircraft Systems (UAS) Pilot Experiment was conducted by the US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory, Field Research Facility (FRF), to assess the potential for different UAS to support US Army Corps of Engineers coastal and flood risk management. By involving participants from multiple ERDC laboratories, federal agencies, academia, and private industry, the work unit leads were able to leverage assets, resources, and expertise to assess data from multiple UAS. This report compares datasets from several UAS to assess their potential to survey and observe coastal terrain and structures. In this report, UAS data product accuracy was analyzed within the context of three potential applications: (1) general coastal terrain survey accuracy across the FRF property; (2) small-scale feature detection and observation within the experiment infrastructure area; and (3) accuracy for surveying coastal foredunes. The report concludes by presenting tradeoffs between UAS accuracy and the cost to operate to aid in selection of the best UAS for a particular task. While the technology and exact UAS models vary through time, the lessons learned from this study illustrate that UAS are available at a variety of costs to satisfy varying coastal management data needs.

Résumé :
The US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory (CHL) expanded the Coastal Hazards System (CHS) to quantify storm surge and wave hazards for coastal Louisiana. The CHS Louisiana (CHS-LA) coastal study was sponsored by the Louisiana Coastal Protection and Restoration Authority (CPRA) and the New Orleans District (MVN), US Army Corps of Engineers (USACE) to support Louisiana’s critical coastal infrastructure and to ensure the effectiveness of coastal storm risk management projects. The CHS-LA applied the CHS Probabilistic Coastal Hazard Analysis (PCHA) framework to quantify tropical cyclone (TC) responses, leveraging new atmospheric and hydrodynamic numerical model simulations of synthetic TCs developed explicitly for the Louisiana region. This report focuses on documenting the PCHA conducted for the CHS-LA, including details related to the characterization of storm climate, storm sampling, storm recurrence rate estimation, marginal distributions, correlation and dependence structure of TC atmospheric-forcing parameters, development of augmented storm suites, and assignment of discrete storm weights to the synthetic TCs. As part of CHS-LA, coastal hazards were estimated within the study area for annual exceedance frequencies (AEFs) over the range of 10 yr-1 to 1×10-4 yr-1.

Texte intégral
Résumé :
Coastal foredunes are topographically high features that can reduce vulnerability to storm-related flooding hazards. While the dominant aeolian, hydrodynamic, and ecological processes leading to dune growth and erosion are fairly well-understood, predictive capabilities of spatial variations in dune evolution on management and engineering timescales (days to years) remain relatively poor. In this work, monthly high-resolution terrestrial lidar scans were used to quantify topographic and vegetation changes over a 2.5 year period along a micro-tidal intermediate beach and dune. Three-dimensional topographic changes to the coastal landscape were used to investigate the relative importance of environmental, ecological, and morphological factors in controlling spatial and temporal variability in foredune growth patterns at two 50 m alongshore stretches of coast. Despite being separated by only 700 m in the alongshore, the two sites evolved differently over the study period. The northern dune retreated landward and lost volume, whereas the southern dune prograded and vertically accreted. The largest differences in dune response between the two sections of dunes occurred during the fall storm season, when each of the systems’ geomorphic and ecological properties modulated dune growth patterns. These findings highlight the complex eco-morphodynamic feedback controlling dune dynamics across a range of spatial scales.

Texte intégral
Résumé :
A physical model study investigating the dissipation of wave energy by a 1:2.1 scale North American red mangrove forest was performed in a large-scale flume. The objectives were to measure the amount of wave attenuation afforded by mangroves, identify key hydrodynamic parameters influencing wave attenuation, and provide methodologies for application. Seventy-two hydrodynamic conditions, comprising irregular and regular waves, were tested. The analysis related the dissipation to three formulations that can provide estimates of wave attenuation for flood risk management projects considering mangroves: damping coefficient β, drag coefficient C𝐷, and Manning’s roughness coefficient 𝑛. The attenuation of the incident wave height through the 15.12 m long, 1:2.1 scale mangrove forest was exponential in form and varied from 13%–77%. Water depth and incident wave height strongly influenced the amount of wave attenuation. Accounting for differences in water depth using the sub-merged volume fraction resulted in a common fit of the damping coefficient as a function of relative wave height and wave steepness. The drag coefficient demonstrated a stronger relationship with the Keulegan–Carpenter number than the Reynolds number. The linear relationship between relative depth and Manning’s 𝑛 was stronger than that between Manning’s 𝑛 and either relative wave height or wave steepness.

Résumé :
This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the continuing efforts towards incorporating rapid tidal time-series reconstruction and prediction capabilities into the Coastal Hazards System (CHS) and the Stochastic Storm Simulation System (StormSim). The CHS (Nadal-Caraballo et al. 2020) is a national effort for the quantification of coastal storm hazards, including a database and web tool (https://chs.erdc.dren.mil) for the deployment of results from the Probabilistic Coastal Hazard Analysis (PCHA) framework. These PCHA products are developed from regional studies such as the North Atlantic Coast Comprehensive Study (NACCS) (Nadal-Caraballo et al. 2015; Cialone et al. 2015) and the ongoing South Atlantic Coast Study (SACS). The PCHA framework considers hazards due to both tropical and extratropical cyclones, depending on the storm climatology of the region of interest. The CHS supports feasibility studies, probabilistic design of coastal structures, and flood risk management for coastal communities and critical infrastructure. StormSim (https://stormsim.erdc.dren.mil) is a suite of tools used for statistical analysis and probabilistic modeling of historical and synthetic storms and for stochastic design and other engineering applications. One of these tools, the Coastal Hazards Rapid Prediction System (CHRPS) (Torres et al. 2020), can perform rapid prediction of coastal storm hazards, including real-time hurricane-induced flooding. This CHETN discusses the quantification and validation of the Advanced Circulation (ADCIRC) tidal constituent database (Szpilka et al. 2016) and the tidal reconstruction program Unified Tidal analysis (UTide) (Codiga 2011) in the Puerto Rico and U.S. Virgin Islands (PR/USVI) coastal regions. The new methodology discussed herein will be further developed into the Rapid Tidal Reconstruction (RTR) tool within the StormSim and CHS frameworks.

Résumé :
The US Army Corps of Engineers, Galveston District, is executing the Sabine Pass to Galveston Bay Coastal Storm Risk Management (CSRM) project for Brazoria, Jefferson, and Orange Counties regions. The project is currently in the Pre-construction, Engineering, and Design phase. This report documents coastal storm water level (SWL) and wave hazards for the Freeport CSRM structures. Coastal SWL and wave loading and overtopping are quantified using high-fidelity hydrodynamic modeling and stochastic simulations. The CSTORM coupled water level and wave modeling system simulated 195 synthetic tropical storms on three relative sea level change scenarios for with- and without-project meshes. Annual exceedance probability (AEP) mean values were reported for the range of 0.2 to 0.001 for peak SWL and wave height (Hm0) along with associated confidence limits. Wave period and mean wave direction associated with Hm0 were also computed. A response-based stochastic simulation approach is applied to compute AEP values for overtopping for levees and overtopping, nappe geometry and combined hydrostatic and hydrodynamic fluid pressures for floodwalls. CSRM crest design elevations are defined based on overtopping rates corresponding to incipient damage. Survivability and resilience are evaluated. A system-wide hazard level assessment was conducted to establish final recommended system-wide elevations.
