Each year storms impact coastal areas, sometimes causing significant morphologic change. Cold fronts are associated with increased wave energy and frequently occur during the winter months along many coasts, such as the Atlantic and Gulf of Mexico. The higher wave energy can be responsible for a large quantity of the sediment transport resulting in rapid morphologic change. Using streamer traps, the vertical distribution of onshore-directed sediment transport during two different cold fronts on two low-wave energy beaches (i.e., along the northern Yucatan and southeast Florida) were compared with the resulting morphologic change. The objectives of this study are to: 1) analyze the grain size distribution (statistics) of sediment transported during a cold front, 2) compare the vertical sediment distribution throughout the water column, and 3) compare characteristics of bed sediment to the sediment within the water column. Understanding the changing grain size distribution of bottom sediments in comparison to directional transport (throughout the water column) should help determine the sediment fraction(s) being eroded or deposited, which could greatly improve predictions of storm-induced morphology change. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

In Australia, Integrated Coastal Zone Management (ICM) is the policy framework adopted by government to manage the coastal zone. Amongst other principles, ICM contains an explicit mandate to include local communities in the management of the coastal zone. In Australia, the Coastcare program emerged in response to international acceptance of the need to involve local communities in the management of the coastal zone. This dissertation is a critical cultural investigation of the Coastcare program to discover how the program and the coastal zone generally, is understood and negotiated by three volunteer groups in SE Queensland. There is a paucity of data surrounding the actual experiences of Coastcare volunteers. This dissertation begins to fill this gap in our knowledge of local community involvement in coastal management. My dissertation considers the culture of Coastcare and broadly, community participation initiatives. Coastcare participants, government policymakers, environmental scientists, etc bring to their encounter a specific ‘way of seeing’ the coast – a cultural framework – which guides their actions, ideas and priorities for the coastal zone. These cultural frameworks are established and maintained in the context of unequal relations of power and knowledge. The discourses of environmental science and economics – as evidenced in the chief ICM policy objective, Ecologically Sustainable Development (ESD) – are powerful knowledges in the realm of community participation policy. This arrangement has serious consequences for what governments and experts can expect to achieve via community participation programs. In short, the quest for ‘power-sharing’ with communities and ‘meaningful participation’ is impeded by dominant scientific and economic cultures which act to marginalise and discredit the cultures of communities (and volunteers). Ironically enough, the lack of consideration of these deeper relations of power and knowledge means that the very groups (such as policymakers, environmental scientists, etc) who actively seek the participation of local communities, contribute disproportionately to the relative failure of community participation programs. At the very least, as those in a position of power, policymakers and associated experts do little to enhance communication with local communities. To this situation add confusion wrought by changes in the delivery of the Coastcare program and a lack of human and financial resources. From this perspective, the warm and fuzzy sentiment of Coastcare can be understood as the ‘Coastcare of neglect’. However, the emergence of community participation as ‘legitimate’ in environmental policymaking indicates a fissure in the traditional power relations between communities and experts. Indeed the entry of ‘community participation policy’ is relatively new territory for the environmental sciences. It is this fissure which I seek to explore and encourage via the application of a cultural studies framework which offers another ‘way of seeing’ community participation in coastal and marine management and thereby, offers avenues to improve relations between communities and experts. My fieldwork reveals a fundamental mismatch between the cultural frameworks which communities bring to the coast and those frameworks embodied and implemented by the Coastcare program. Upon closer examination, it is apparent that the Coastcare program (and community participation programs generally) are designed to introduce local ‘lay’ communities to environmental science knowledge. Local coastal cultures are relegated to the personal and private realm. An excellent example of this is the scientifically oriented ‘eligible areas for funding’ of the Coastcare program. The volunteers consulted for this project emphasized their motivation in terms of ‘maintaining the natural beauty of the coast’ and ‘protecting a little bit of coast from the rampant development of the coastal zone’. Their motivations were largely the antithesis of ESD. They understood their actions as thwarting the negative impacts of coastal development – this occurred within a policy framework which accepted development as fait d’accompli. Australia’s nation of coastal dwellers may not know a lot about ‘coastal ecologies’ but they do know the coast in other ways. Community knowledge of the coast can be largely accounted for in the phrase, ‘Australian beach culture’. Serious consideration of Australian beach culture in environmental policy is absent. The lack of attention to this central tenet of the Australian way of life is because, as a concept and in practice, beach culture lacks the ‘seriousness’ and objectivity of environmental science knowledge – it is about play, hedonism, holidays, spirituality, emotion and fun. The stories (including Indigenous cultural heritage) which emerge when Australians are asked about their ‘beach cultural knowledge’ – historical and contemporary experiences of the Australian coast – await meaningful consideration by those interested in communicating with Australian communities living on the coast. This ‘cultural geography’ is an avenue for policymakers to better communicate and engage with Australian communities in their quest to increase participation in, or motivate interest in community coastal management programs.

The coastal zone of Belize is home to the largest recorded number of the threatened Antillean manatee (Trichechus manatus manatus) within the species' Caribbean range. The objectives of my study were: (1) to determine long-term trends in aerial survey counts and indices of the manatee population in the coastal zone of Belize; and (2) to examine the seasonal change in manatee distribution among habitats in the coastal zone. Standardized extended-area aerial surveys were conducted along the entire coastline of Belize in the dry and wet seasons of 1997, and 1999 - 2002. Manatees were counted in five habitat categories: cay, coast, estuary, lagoon, and river. Total sightings per survey ranged from 90 to 338; the greatest number was counted in the 2002 wet season. Calf percentage ranged from 5 to 13. A slight negative trend in total counts was significant for dry-season, not wet-season surveys, indicating an interactive effect of season and year. Based on analysis of variance, the Abundance Index (transformed manatee sightings per hour) did not differ significantly among years, although it varied significantly within year by season and habitat by season. In applying a spatial approach, the general survey route was buffered 1 km on both sides, and 1 km grids were overlaid and classified by habitat type. The presence or absence of each cell for each survey was used in likelihood ratio tests of the single and interactive effect of season and habitat. The Index for river habitat was higher in the dry season, while cay habitat was higher in the wet season. Overall, near-shore habitat (estuary, lagoon, and river) showed a higher Index than did the offshore habitat (cay and coast) although the total number of sightings was higher offshore. Considering the interactive effect of year, season, and habitat, long-term studies are needed, in both seasons, and among all habitats to account for variation. Continued broad-scale surveys, along with metapopulation analysis would fine-tune the understanding of specific sites, enhancing integrated coastal zone management for protected species and their habitat systems.

Coastal regions provide a lot of resources and benefits for all the humankind. For economic growth, these resources are needed. On the other hand, coastal resources should be maintained and preserved in some limits. Sustainable development is aimed to set a balance between economic growth and preserving the nature. Determination of the yacht carrying capacity is a major step for sustainable development. In this thesis study wind-induced water circulation in semi-enclosed basins are carried out in order to reach the yacht carrying capacity for Fethiye Bay. Hydrodynamics of bays is very complex, mainly affected by wind and wave climate and sea bottom topography. The sea bed profiles at the bay changes under winter and summer storms of different speeds and directions. This case study will be carried out with the developed methodology. The present structure of Fethiye Bay will be analyzed and necessary measurements will be proceeded. Moreover, two more cases will be studied besides the present conditions. Circulation models will be applied to the study case according to reached data. For this purpose, Finite Volume Coastal Ocean Model (FVCOM) numerical model will be used.

This study focuses on the determination of locality of Integrated Coastal Zone Management studies in Turkish legislation and applicability. Accordingly the process of the awareness of necessity for Integrated Coastal Zone Management in the world, related definitions, concepts and implementations, international institutional organizations and planning management experiences of different countries are firstly investigated. Afterwards coastal legislation, coastal planning process, recent studies in order to regulate authority in Turkey and as a result management, legislation, authority is evaluated. Finally Izmit Gulf (Kocaeli- Yalova) Integrated Coastal Zone Planning and Management Project are examined as a case study. State of Izmit Gulf, basic principles, zoning decisions and suggested strategies and activities are scrutinized. This study is also the first compilation concerning recent changes in planning legislation in Turkey related to ICZM studies.

Coastal zone become the object which is used to develop when the economy developed quickly and population increase. As a result of coastal zone is a region which involves economy, environment, ecology, and engineering. We must integrated many factors and coordinated related groups. Then we can achieve the goal of sustainable development. The research involved the knowledge and experiences from Europe, American, and Japan. Except they used a construct of Integrated Coastal Zone Management (ICZM) to think the questions, they combined ecology, water conservancy engineering, social economic activities, and environmental protection. Then they used DSR framework as the foundation to establish the system which evaluated sustainable development of the coastal zone, and they can develop the system dynamic model analyzing the coastal management in many conditions. Land subsidence is a potential crisis, it grows obviously with the time and has the impact to the environment., When typhoon occurs in the west part of Taiwan coastal area, draining which is unable to operate may cause flood, mole avalanche, seawater intrusion and soil salinization. First we must understand the origin and the management of land subsidence, then we can make the effective strategies by researching different background and geography characteristic of the region. As a result of land subsidence involves economy, environment, ecology and engineering, the process of land subsidence is a complex problem which has multiple causes. This problem usually involves time-delay and long-term effect. System dynamics is an approach that is used to describe, explore and analyze the procedure, information and the boundary of organizations in complex systems. Such model is good for solving dynamic complex problems with non-linearity, causal circulation, information feedback and time-delay as long as the estimative parameter fall in its confidence level. The object of the research is to inspect land subsidence in the Pingtung plain. Therefore, this study proposes to find strategies which is suitable to solve interested problems according to integrate social-economic and ecologic-environment development. The framework of the research is based on the DSR (Driving forces-State-Response) index, and it makes evaluated factor from collecting domestic and foreign literature. Then we selected the important factors and its weight value by using the method of AHP (Analytic Hierarchy Process) to visit the expert and the scholar. According to above, we developed the model of system dynamics and build confidence in the model. In addition, the result of the simulation can provide good supporting information for decision makers by using the model for several strategies simulation and making the index to represent the performance of simulation analysis.

The coastal zone including coastal waters and littoral zone are influenced by the interactions between sea and land, and the resources of coastal areas have significant functions and values whatever the regards of nature ecology, industry development, transportation, tourism, national defense, and academic research. Following the population growth, economic advancement, and the change of industry, the land use of coastal zone is more diverse and complex. The incompatible between development and marine environment was happened sometimes. In order to solve the conflicts of coastal resources multiple use and mitigate the negative effects by human activities, integrated coastal zone management was become the most important way for sustainable using the sea. ¡§Integrated Coastal Zone Management (ICZM)¡¨ is a resource management system applying the process of integration, connection, and interaction, to analyze the complicated management problem at coastal areas. It is also a framework of principles and methodology for identification of important environmental priorities and allocation of scarce resources. It is an integrated management planning process emphasizing the comprehensive aspect to achieve the sustainable development of the coastal zone. Because the laws and regulations about land planning and coastal zone management is under legislation and the ¡§Coastal Zone Management Plan¡¨ of Kaohsiung County is not accomplished, the research attempts to understand the future development concept and direction about coastal areas in Kaohsiung County according to ¡§Kaohsiung County Comprehensive Development Plan¡¨. The research formulates some phenomena at present involving artificial construction causing coastal erosion, making land destroying the ecology, development project standing, development location overlapping, project contents competing each other, objective scale too large, disregard environmental sensitive areas, using a lot of hard structures, etc. Furthermore, we survey the planning and management of coastal zone through the aspects of integration among sectors, between the land and the water sides of the coastal zone, among levels of government, and among disciplines. Synthesizing the discussions of research, we can find the major problem of coastal zone management at Kaohsiung County is not lacking of planning project, instead of having too many but the implement result is not satisfactory. It is perceived that investigating and evaluating of the resource supply and the user demand at advance planning process was insufficient. Besides, it didn¡¦t have a comprehensive development plan which thinks about coastal environment from the first to be a basis of integration and coordination the various land use. Expecting the future coastal zone development and management, the responsible agency and project proponent can discard the departmental egoism, prior consider the integrated environment, proceed to communication, coordination, and integration continuously in search of a common consensus and vision. Only if that, the coastal zone development can be sustainable.
