Streszczenie:

In response to the increasing occurrences of beach erosion along Surfers Paradise and Main Beaches - Gold Coast, Australia, the Northern Gold Coast Beach Protection Strategy [NGCBPS] was developed to widen the beach by 20-30m as well as improving surfing conditions as a secondary objective. The strategy, implemented in 1999- 2000, involved large-scale beach nourishment and construction of a submerged breakwater “reef” to act as a control point at Narrowneck. Construction of the reef involved innovative filling and placement methods using very large sand filled geotextile containers coupled with significant advances with regards to design of the geotextile material and containers. In the 11 years since construction, there has been substantial monitoring of the project since its completion in late 2000 including: - video imaging using webcams; hydrographic and beach surveys; aerial and oblique photography; surf and surf safety observations and GPS surfing track plots; and geotextile container condition and stability. This paper presents an update on the performance of the reef over the last four years. In particular, the response of the structure and the shoreline to a series of major storm events in 2009 has been examined. The results have shown that the erosion caused by these major events was accommodated within the wider beach created in 1999. Over the next 2 years there was a gradual recovery in the lee of the reef with a subtle groyne effect resulting in an even larger increase in the width of the updrift beach. A detailed underwater condition survey was also undertaken in 2011, to determine changes in the condition of the geotextile containers. This revealed a number of containers missing or damaged, and that seaward containers were covered by sand. The marine habitat which has been a feature of the reef has been impacted by the increased coverage of sand, but still shows high abundance and biodiversity.

Climate change impacts, sea level rise, and changes to the frequency and intensity of storms, in particular, are projected to increase the coastal land and assets exposed to coastal erosion. The selection of appropriate adaptation strategies requires an understanding of the costs and how such costs will vary by the magnitude and timing of climate change impacts. By drawing comparisons between past events and climate change projections, it is possible to use experience of the way societies have responded to changes to coastal erosion to inform the costs and selection of adaptation strategies at the coastal settlement scale. The experience of implementing a coastal protection strategy for the Gold Coast’s southern beaches between 1964 and 1999 is compiled into a database of the timing, units, and cost of coastal protection works. Records of the change to shoreline position and characteristics of local beaches are analysed through the Bruun model to determine the implied sea level rise at the time each of the projects was completed. Finally, an economic model updates the project costs for the point in the future based on the projected timing of sea level rise and calculates a net present value (NPV) for implementing a protection strategy, per km, of sandy beach shoreline against each of the four representative concentration pathways (RCP) of the Intergovernmental Panel on Climate Change (IPCC) to 2100. A key finding of our study is the significant step-up in expected costs of implementing coastal protection between RCP 2.6 and RCP 8.5—from $573,792/km to $1.7 million/km, or a factor of nearly 3, using a social discount rate of 3%. This step-up is by a factor of more than 6 at a social discount rate of 1%. This step-up in projected costs should be of particular interest to agencies responsible for funding and building coastal defences.

The creation and protection of surfing breaks along populated coastlines have become a consideration for many councils and governments as surfing breaks are a major driver of tourism. To assess the surf amenity of surfing breaks, a quantitative and objective assessment method is required. A new wave peel tracking (WPT) method has been developed using a shore-based camera to assess surf amenity by measuring and quantifying potential surfing ride rate, length, duration, speed and direction on a wave-by-wave basis. The wave peel (or “curl” below the wave peak) is the optimal surfing region on a wave, and each wave peel track represents a surfable ride. Wave peel regions are identified, classified and tracked using traditional and machine learning-based computer vision techniques. The methodology is validated by comparing the rectified wave peel tracks with GPS-measured tracks from surfers in the wave peel regions. The WPT methodology is evaluated with data from a reef and adjacent natural beach at the Gold Coast, Australia. The reef produced longer ride lengths than the nearshore region and showed a consistent breaking location along the reef crest. Spatial maps of the wave peel tracks show the influence of tides on the wave breaking patterns and intensity. The WPT algorithm provides a robust, automated method for quantifying surf amenity to provide baseline data for surf break conservation. The methodology has potential uses to verify numerical modelling of surf breaks and to assess the impact of coastal development on surf breaks.

The shoreline of northern Colombia is located in the tropical zone along the south coast of Caribbean Sea. Its coastal processes are strongly influenced by the northeast trade wind, which results in the dominating northeasterly approaching wave occurring over 95% of the time. This drives a persistent southwestward longshore sand transport. The state of the beach along the generally northeast-southwest trending northern Colombia coast is strongly influenced by this constant unidirectional longshore sediment transport. At locations where this westward longshore sand transport is interrupted, naturally or anthropogenically, beach accretion occurs along the updrift shoreline coupled with erosion at the downdrift side. Natural interruption of longshore transport can be caused by tidal inlets, protruding headland, shoreline orientation change, and nearshore bathymetry variations. Anthropogenic interruption of the longshore transport along the northern Colombia coast is mainly caused by the construction of groins, as well as harbors at some locations. Numerous groins were constructed due to their local success in creating beach accretion at the drift side. However, severe beach erosion occurs along the downdrift shoreline. Shoreline protection along the northern Colombia coast, and coasts in the tropical area in general, should carefully consider the persistent unidirectional longshore sand transport and should not be misguided by the local updrift accumulation as being a successful project.

AbstractGold Coast beaches oscillate in the cultural imagination between everyday reality and a tourist's paradise of ‘sun, surf and sex’ (Winchester and Everett 2000: 59). While these narratives of selfhood and becoming, egalitarianism and sexual liberation punctuate the media, Gold Coast literary fictions instead reveal the beach as a site of danger, wholly personifying the unknown. Within Amy Barker's Omega Park, Melissa Lucashenko's Steam Pigs, Georgia Savage's The House Tibet and Matthew Condon's Usher and A Night at the Pink Poodle, the beach is a ‘masculine’ space for testing the limit of the coastline and one's own capacity for survival. This article undertakes a close textual analysis of these novels and surveys other Gold Coast fictions alongside spatial analysis of the Gold Coast coastline. These fictions suggest that the Gold Coast is not simply a holiday world or ‘Crime Capital’ in the cultural imagination, but a mythic space with violent memories, opening out onto an infinite horizon of conflict and estrangement.

Gold Coast high-rises are big and tall and sometimes they appear or are made to appear bigger and taller than they really are. They also loom large in other ways. They are part of the fabric and fantasy of the Gold Coast. They are its supreme icons. Only nine per cent of the permanent population lives in high-rises and the canal estates have considerable local cachet and appeal. Yet the city turns to its high-rises not only to promote itself to the rest of the world, but also to hold its own self-image: the Gold Coast City Council sponsors a ‘heritage’ architectural guide to tall buildings on the Gold Coast; the Gold Coast Bulletin constantly features articles on new high-rise plans and developments, high-rise architects, builders and developers, and high-rise residents. No-one seems to complain about views being obscured, at least publicly, and the shadows-on-the-beach argument, once a talking point, has been abandoned—in resignation, perhaps.

The results of the study of the peculiarities of lithodynamics of pebble beaches of the South Coast of Crimea based on the long-term monitoring of the state of beaches performed at the Black Sea Hydrophysical Subsatellite Proving Ground of the Marine Hydrophysical Institute of the Russian Academy of Sciences in the settlement of Katsiveli are presented. Long-term changes of the beach of Limensky Bay since 1950 and of beaches of the shore protection structures since 1988 are characterized. The volume of income and outcome of pebbles during the change of wind-wave regimes was estimated by the example of Limensky Bay beach and the artificial beaches of the coast protection structures in the coastline section from Katsiveli to Ponizovka settlement. The most influential factor in the formation of the pebble beaches of the Southern Coast of Crimea is the change in alongshore wind-wave regimes in the “days-months” time scale, which leads to significant fluctuations in sea level near the coast and a corresponding change in the directions of the bottom current velocity components perpendicular to the shoreline. The largest expense and income of beach-forming material (up to 1 m3/day per linear meter of beach) occurs during storms, respectively, with wind-wave regimes of the eastern and western directions. The largest irreversible removal of the mass of beach-forming materials during the change in wind-wave regimes occurs from the eastern and central sections of the bays and artificial beaches of coastal protection structures, and partial restoration of beaches—on their western sections. Natural underwater reefs in the coastal waters of bays and artificial beaches of shore protection structures contribute to the preservation of beaches in them. The reason for the gradual average long-term degradation of beaches may be the predominance of eastern storm winds over western ones in conditions of blocking the natural income of beach-forming materials from the coast by the coastal infrastructure objects.

This thesis investigated the effects of photographic and text information on respondents' attitudes and willingness-to-pay for a proposed beach protection scheme in the erosion prone Gold Coast region on the east coast of Australia. The research developed two alternative expectancy-value attitude-behaviour models to test residents' attitudes toward relevant targets and behavioural intention, expressed through stated willingness-to-pay, and compared the proposed models with one established attitude-behaviour model. The thesis set out to investigate three central research questions; one question relating to the effects of information on attitudes and willingness-to-pay, and two questions relating to the relationships between attitudes and willingness-to-pay. It was hypothesised that photographs that depicted severe erosion damage would result in more positive attitudes toward, and greater willingness-to-pay for, beach protection than photographs that showed only mild levels of erosion damage. Positive relationships were hypothesised between variables representing attitudes toward beach erosion, attitude toward beach protection, attitude toward paying for beach protection, and willingness-to-pay. Finally, it was hypothesised that the relationships between attitudes and willingness-to-pay could be adequately explained by the proposed attitude-behaviour models. The thesis describes how seven information treatments and eight attitude measurement scales were developed and tested in a pilot experiment before use in a survey of homeowners in the region of interest. Analysis of variance showed that, while respondent's attitude toward beach protection was affected by the information treatments, their willingness-to-pay for the proposed program was insensitive to information. There were no significant effects that could be attributed exclusively to text descriptions of the good but there were significant effects that could be attributed to photographic information treatments. However, none of the effects on attitudes resulted in significant effects on the behavioural intention expressed in stated willingness-to-pay. Analysis of respondents with low previous knowledge of the proposed good revealed more extensive information effects on attitudes, but still not on willingness-to-pay, and this suggests that high levels of previous knowledge in a large proportion of the sample had a moderating effect on attitude change caused by the information treatments. Regression analysis showed that seven of the eight attitude and behaviour variables in the proposed attitude-behaviour model were significant predictors of willingness-to-pay. In the final phase of the analysis, goodness-of-fit indices, estimated using Structural Equation Modelling, indicated a good fit between the data and the attitude-behaviour models tested. Standardised coefficients on the model indicated that perceived behavioural control, expected utility of outcomes, and subjective norms all had strong direct relationships with stated willingness-to-pay, and strong indirect relationships on willingness-to-pay via attitudes toward payment. These results are consistent with the relationships proposed in attitude-behaviour models and the moderating effects of these variables explain why significant information treatment effects were observed on attitude to beach protection but not on willingness-to-pay. This research showed that respondent's willingness-to-pay in a contingent valuation experiment is quite insensitive to photographic treatments when previous knowledge is high and that costly and time consuming testing procedures, recommended by authorities, may not be necessary under these conditions. It also demonstrated that measures of attitude, consistent with an attitude-behaviour model, can be collected easily in a contingent valuation study and can contribute to understanding of participant responses and to identification of protest responses.

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.

Streszczenie:

Although the physical characteristics of surfing breaks are well described in the literature, there is little specific research on surfing and coastal management. Such research is required because coastal engineering has had significant impacts to surfing breaks, both positive and negative. Strategic planning and environmental impact assessment methods, a central tenet of integrated coastal zone management (ICZM), are recommended by this thesis to maximise surfing amenities. The research reported here identifies key oceanographic considerations required for ICZM around surfing breaks including: surfing wave parameters; surfing break components; relationship between surfer skill, surfing manoeuvre type and wave parameters; wind effects on waves; currents; geomorphic surfing break categorisation; beach-state and morphology; and offshore wave transformations. Key coastal activities that can have impacts to surfing breaks are identified. Environmental data types to consider during coastal studies around surfing breaks are presented and geographic information systems (GIS) are used to manage and interpret such information. To monitor surfing breaks, a shallow water multibeam echo sounding system was utilised and a RTK GPS water level correction and hydrographic GIS methodology developed. Including surfing in coastal management requires coastal engineering solutions that incorporate surfing. As an example, the efficacy of the artificial surfing reef (ASR) at Mount Maunganui, New Zealand, was evaluated. GIS, multibeam echo soundings, oceanographic measurements, photography, and wave modelling were all applied to monitor sea floor morphology around the reef. Results showed that the beach-state has more cellular circulation since the reef was installed, and a groin effect on the offshore bar was caused by the structure within the monitoring period, trapping sediment updrift and eroding sediment downdrift. No identifiable shoreline salient was observed. Landward of the reef, a scour hole ~3 times the surface area of the reef has formed. The current literature on ASRs has primarily focused on reef shape and its role in creating surfing waves. However, this study suggests that impacts to the offshore bar, beach-state, scour hole and surf zone hydrodynamics should all be included in future surfing reef designs. More real world reef studies, including ongoing monitoring of existing surfing reefs are required to validate theoretical concepts in the published literature.

Surf zone circulation patterns are recognised in the literature as having an important influence on cross- and alongshore exchange of water, sediment, and floatsam in the surf zone. Any study of surf zone circulation patterns therefore has implications for sediment transport, biological processes and beach safety, with the majority of studies focusing upon rip current circulation and rates of cross-shore exchange of drifters due to rip currents. The aim of recent research has been to describe surf zone circulation patterns and retention of floatsam in the surf zone, with a major focus on informing rip current escape strategies and hazard mitigation. Previous studies have focused upon single bar embayed beaches in a microtidal environment or open coast beaches in a mesotidal or macrotidal environment, exposed to a generally shore-normal wave climate and displaying relatively stable bar morphology. This thesis explored surf zone circulation patterns and transient rip currents on the open beaches of the northern Gold Coast, Australia. These beaches are characterised as being microtidal and wave dominated, double bar, open coast beaches with no bounding headland morphology. The beaches are exposed to a highly variable wave climate, which is often bimodal and bidirectional and the dominant angle of wave approach is oblique to the shoreline. The double bar beach state combinations are complex and highly dynamic and sandbar and rip features are often skewed in response to the oblique angle of wave approach and prevailing longshore current.

The movement of sediment in the nearshore zone is of particular interest along many densely populated sandy coastlines throughout the world. The city of the Gold Coast in southeast Queensland, Australia, is such a location. With residential and apartment buildings built close to the shoreline, it has a history of property threatening erosive events which make knowledge of the transport of the sandy sediment that lines its beaches a prime concern. Between 1880 and 1910, training walls were constructed at the mouth of the Tweed River. They were extended in the early 1960's. This construction has interrupted the supply of sediment to the Gold Coast from its updrift (southern) border. The resultant reduction in sediment supply has severely depleted the protective barrier formed by offshore shoals, increasing the volume of sediment required from the nearshore reserves in times of high energy wave conditions such as those experienced in storms and cyclones. Analysis centered on a suite of samples collected in 1972, and later sieved by Gold Coast City Council soils laboratory staff The samples were collected on five shore normal lines, distributed along the Gold Coast shoreline. Seven boreholes were sampled along each of these lines in water depths ranging from 6 - 30 m. Each borehole was drilled to 4.5 m into the sea bed, samples being collected in 0.75 m sections. This drilling program gave the 210 samples used in this thesis. Several researchers have indicated a limiting water depth for the nearshore active zone of about 12-15 m for sediment in this region. Results from this analysis indicate that this depth is indeed important in the distribution of sediment in this region. However it appears to be better described as a boundary between two energy systems. The sediment distribution in the onshore and offshore directions are determined at this boundary. Findings show that at this boundary the sediment shows the following properties: • Percent fines which is

En Asie du Sud-Est, la dynamique côtière est régie par un équilibre spécial entre les moussons du nord-est et sud-ouest. Dans un contexte de l'élévation du niveau de la mer et d’un changement climatique avéré, les régimes de la mousson ont commencé à évoluer et à modifier les équilibres hydro-morpho-sédimentaires sensibles au niveau des espaces littoraux. Cette situation engendre des phénomènes d'érosion le long du littoral, notamment le littoral NE de la Malaisie. Cependant, les autorités publiques ont tenté d'atténuer les problèmes d'érosion par la construction d’ouvrages de défense côtière. Ces derniers peuvent affecter le régime des houles, la circulation hydrodynamique et le transport des sédiments, réduisant ainsi la capacité du rivage à répondre aux facteurs du forçage naturels (régime de la double saison de mousson) et à fragmenter l'espace côtier. La présente thèse explore les problèmes des phénomènes d'érosion, l'évolution du littoral et la morphodynamique des plages le long du rivage de Kuala Terengganu sur la côte Est de la Malaisie péninsulaire par rapport aux facteurs naturels et anthropiques. Cette étude a été menée en trois phases pour aborder les sujets suivants: i) évolution long terme du trait de côte du littoral NE de la Malaisie de 2006 à 2014; ii) évolution moyen terme du littoral (suivi mensuel) de juillet 2013 à juin 2015 et; iii) suivi court terme à travers des campagnes de mesures hautes fréquences (mesures topographiques, hydrodynamiques et de transport des sédiments) sur quelques sites du littoral NE de la Malaisie pendant les moussons nord-est et sud-ouest. Sur la base d'un modèle morphodynamique pour simuler les processus saisonniers, il est apparu que l'érosion domine la plupart des stations suivies sur le littoral pendant la période de la mousson du nord-est, tandis que l'accrétion ou la recouvrement sédimentaire des plages sont observés pendant les moussons du sud-ouest
In Southeast Asia, coastal dynamics are governed by a special equilibrium between northeast an southwest monsoons. In the context of sea-level rise and climate change, the monsoon regimes create an adaptation of the coastal dynamics. This situation gives rise to erosion phenomena along the coastline. However, public authorities have attempted to mitigate the problems of erosion by the construction of coastal defence structures. However, artificial structures can affect the wave regime, hydrodynamic circulation and sediment transport, thus reducing the ability of the shoreline to respond to natural forcing factors (such as with double monsoon season regimes) and also fragmenting the coastal space. The present thesis explores the problems of erosional phenomena, shoreline evolution and beach morphodynamics along the Kuala Terengganu shoreline on the East Coast of Peninsular Malaysia, with the aim of understanding the natural versus anthropogenic factors. This study was conducted in three phases to address the following topics: i) shoreline evolution from 2006 to 2014; ii) mid-term surveys (bi-monthly) involving data collection from July 2013 until June 2015 and; iii) short-term surveys (twice daily) with data collection (Topographic, hydrodyanamic and sediment transport measurments) during northeast and southwest monsoons. Based on a morphodynamic model for simulating seasonal processes, erosion is found to dominate most of the stations during northeast monsoons, while accretion or beach recovery is observed during southwest monsoons

The vulnerability of today's information economy is still not sufficiently realised: The economic structure of Queensland is to a great extent made up of Small and Medium Enterprises (SME). Across all industry sectors, these businesses rapidly approach a similar level of information technology take-up than large enterprises and thus depend to an increasing degree on IT efficiency and security. The findings of this study, which has been conducted in partnership with the Information Industries Bureau and the Gold Coast City Council, are drawn from an online survey in order to provide an indication of the present e-security situation in SMEs of Queensland's Gold Coast region. The data shows that the installation and maintenance of e-business technology requires significant time, staff and money resources as well as a constant learning and updating process in order to be on top of the IT development, which is why most SMEs rely to a substantial degree on the expertise and competence of external IT service providers and consultants. E-Business technology is subject to various vulnerabilities. It is necessary to conduct proper risk analysis to gauge the impact and likelihood of any potential business threats. The risks identified in this process have then to be treated with appropriate backup plans. SMEs seem to be overstrained to handle this burden by themselves without the availability of support programs to reasonable charges, for specialised e-security service providers do not target SMEs. Their solutions are too pricey and are not designed to be applied in the setting of a SME. The Queensland Government shows a high level of interest in issues surrounding e-business and their usage. However, e-security issues in SMEs are rarely addressed. Many public funding and assistance schemes seem to be unknown, unattractive, or unsuitable to SMEs. There is an obvious lack of awareness for security issues among SMEs which has to be addressed by developing new and rethinking existing public programs and strategies. To stimulate awareness and appropriate action, it is desirable to provide certain incentives and rewards to enterprises that pass security audits and fulfil Australian security standards. These are essential steps towards the protection against and preparedness for any e-security incidents which both the public and private sector have to take in order to survive something Sam Nunn calls an "electronic Pearl Harbor".

These shorelines are analyzed to show the shoreline evolution of the Gold coast and to investigate the Wan Li beach erosion. The techniques of image processing include erasing wave whitecaps, image enhancement, morphological image processing and Canny methods are used to accurately detect the waterline of a pan-satellite image. Interpolated water level at the shooting time of an image from observed tidal data associated with shoreface beach slope is to determine the shoreline by a horizontal distance through trigonometrical identities. The biases between the detected shorelines and measured ones are 0.35m and 0.92m respectively for 2006 and 2010. The corresponding RMSEs are 6.52m and 5.5m. The results are close to those of Tsai(2017), indicating the application of the proposed method to the shoreline change. The rates of summer, winter and anuual shoreline from 2003 to 2014 are negative, showing that the Wan Li beach is suffering from erosion. The longshore sediment discharge and river sediment discharge are estimated by some empirical formulas based on wave data of the Harbor and Marine Technology Center and discharge as well as sand suspension data of the Water Resources Agency. The annual averaged river sediment transport is approximate 1-2% of in the longshore sediment transport from 2003 to 2014. The longshore sediment transport increases with time, but the river sediment transport decreases with time. Through two-variable regression analysis and F-value test the longshore sediment transport is the dominant factor in the shoreline changes. The river sediment transport is not significant to affect the shoreline changes.

This chapter describes Still’s life in Africa. He was stationed at an airbase near Accra on the Gold Coast, in what is now Ghana. He was the Personnel Sergeant Major and kept records of everything at the base. He met the challenges of the job and enjoyed the nearby beach, but he found the best aspect of his military experience to be the opportunity for travel and adventure in Africa, Egypt and the Holy Lands. He read widely but wrote and published little while overseas.

"large audience” (Goldstein 1983: 26); and “Here was an Australian with a wry sense of humor and gruff charm [this was post-Crocodile Dundee], equally alluring to men and women” (Brown 1987: 33). In other words, Robert Scorpio is conveniently – if not tokenistically – played by an Australian. The limits of tolerance of the non-American for the world of network soap are instanced in General Hospital’s casting criteria for an (American) actor to play Robert Scorpio’s long-lost brother, Malcolm. The actor, John J. York, is quoted in the ABC house journal, Episodes, saying: “They didn’t want a strong dialect [sic] . . . . They didn’t want a Paul Hogan type, because that accent is too strong. They were saying ‘just a hint’” (Kump 1991: 29). The Australian is more “exotic” than Peter Pinne may have wished: too exotic. Just the accent, though, if muted, can have an appealing otherness. The second index of the acceptability of the non-American, again Australian, has yet to be tested on the American market place. Called Paradise Beach, it is not a ready-made Australian soap seeking overseas sales, but a co-production between the Australian-based Village Roadshow, Australia’s Channel 9, and the American New World Entertainment, which has secured pre-sales to the CBS network at 7:30 p.m. week-nights (beginning June 14, 1993) and Britain’s Sky Channel as well as in nine other territories worldwide (Gill 1993; Chester 1993; Shohet 1993). As an Australian-based soap directed primarily at a teen audience, it recalls Neighbours and Home and Away. As a youth drama serial set in a beach tourism center, it recalls Baywatch and summer holiday editions of Beverly Hills 90210. And like Melrose Place and the Australian E Street, each episode includes what one report breathily calls “an MTV moment . . . a two-minute montage of sleek shots of beautiful bodies and plenty of sun, surf and sand set to the latest pop music hit” (Shohet 1993: 5). Set in and around Surfers Paradise on Queensland’s Gold Coast, it recalls, for Australian viewers, the 1983 film, Coolangatta Gold, which celebrates Australian beach culture (see Crofts 1990). It is noteworthy indeed that most of the performers are recuited from a model agency, not an actor’s agency. An American actor, Matt Lattanzi, plays an American photographer, and Australian actor, Tiffany Lamb, sports an American accent. There is a concern, understandable in a program sold overseas, to make Australian colloquialisms comprehensible (Gill 1993: 2). In terms of physical geography, the locations are Australian; in terms of cultural geography, Queensland’s Gold Coast is substantially indistinguishable from much of Florida and parts of California and Hawaii. The era of the co-production re-poses the question of the degree of acceptability of non-American material in the American market-place by begging the question of the distinguishability of the two. But given the unequal cultural exchange long obtaining between Australia and the US, with shows like Mission: Impossible being filmed in Australia to take advantage of cheap labor; given the tight money of Paradise Beach’s shooting schedule of 2.5 hours of soap per week; and given New World’s Head’s, James McNamara, ignorance of Australian soaps (“Paradise Beach is the first soap to be skewed at a teen audience” (quoted by Gill 1993: 2)), one might wonder which party is defining the".

The Imeretinsky lowland – the central fragment of a large Black Sea terrace of the Caucasian coast of Russia, is located in interfluve the rivers Mzymty and Psou. In its central and western part large sports complexes of the winter Olympic Games "Sochi-2014" and the Olympic village are under construction. It has led to necessity of engineering protection of coast from the constructed port Imeretinsky to east board of cape of Konstantinovsky. In the report the site located from the Southern pier of port to the western board of cape of Konstantinovsky is considered. On a site the underwater canyon Novuy is located. To provide stability of a shore, the project of coastal protection now is realized. This project provides building in a surface part of a beach ferroconcrete grille on piles and a slope from concrete cubes. Before should be fill an artificial pebble beach in width not less than 50 m. As has shown inspection of coastal protection constructions, rates a beach lag behind rates of its washout. The width of a surface beach makes now no more than 13 m. For scoping executed embankments sandy a material comparison bathymetric shootings before port building (2007) has been made and April, 2012. By comparison is established that slept pebble the material is at the bottom and doesn't move waves on coast. Thus, massed filling the pebble material, coasts of Imeretinsky lowland spent recently on a considered site, haven't led to formation of a steady surface beach in design width of 50 m. On this site, and also on a site around Konstantinovsky's canyon updating of design decisions is required.

A model of an artificial beach is suggested for protection of coasts under erosion due to intense storm surges. It is shown that the coarser beach sand results in decrease of the beach width and growth of nourishment volume. At the same time relative material loss due to long-shore sediment transport diminishes too. The model has been applied to three sections of the coasts of Kurortny district of S.-Petersburg (eastern part of the Gulf of Finland). It recommends medium sand for the beaches construction. Modeling of extreme storms effect shows only minor deformations for designed beach profiles. For the beaches more than 1 km long even in 30-50 years more than a half of the initial beach volume conserves without additional nourishment.

This technical report presents two applications of the GenCade model to simulate long-term shoreline evolution along the Delaware Coast driven by waves, inlet sediment transport, and longshore sediment transport. The simulations also include coastal protection practices such as periodic beach fills, post-storm nourishment, and sand bypassing. Two site-specific GenCade models were developed: one is for the coasts adjacent to the Indian River Inlet (IRI) and another is for Fenwick Island. In the first model, the sediment exchanges among the shoals and bars of the inlet were simulated by the Inlet Reservoir Model (IRM) in the GenCade. An inlet sediment transfer factor (γ) was derived from the IRM to quantify the capability of inlet sediment bypassing, measured by a rate of longshore sediments transferred across an inlet from the updrift side to the downdrift side. The second model for the Fenwick Island coast was validated by simulating an 11-y ear-long shoreline evolution driven by longshore sediment transport and periodic beach fills. Validation of the two models was achieved through evaluating statistical errors of simulations. The effects of the sand bypassing operation across the IRI and the beach fills in Fenwick Island were examined by comparing simulation results with and without those protection practices. Results of the study will benefit planning and management of coastal sediments at the sites.
