| Countries in the Caribbean region, including Belize, are vulnerable to coastal erosion. Experts and scholars have assessed the effects of coastal erosion in the region in physical and economic terms, most often from a sectoral perspective. However, less attention has been directed to the localized and nonquantifiable effects of coastal erosion in the region. We address this research gap by presenting an empirical study of a village in southern Belize that has experienced significant coastal erosion since the mid-1980s. Drawing on interviews, a mapping exercise, and a literature review, we analyze how villagers are experiencing the impacts of coastal change, and what the resulting risks and losses mean for the socioeconomic stability of the village. We... |

| Knowledge regarding the systemic vulnerability of coastal territories to erosion and flood has progressed during the last decades thanks to the consideration of hazards but also of other components such as the stakes, the management and the social representations of the coastal risks. However, in numerous cases the development and urbanization of coastal territories submitted to the coastal risks continues. It results in the increase of exposed populations as well as in the increase of the cost of exposed properties, increasing in return their vulnerability. So, in the objective to improve the management strategies and to strengthen the memory of the risk, the need to specify the characteristics of hazards remains important. In this sense, the intensity,... |

| Coastal boulder deposits (CBD), transported by waves at elevations above sea level and substantial distances inland, are markers for marine incursions. Whether they are tsunami or storm deposits can be difficult to determine, but this is of critical importance because of the role that CBD play in coastal hazard analysis. Equations from seminal work by Nott (1997), here referred to as the Nott Approach, are commonly employed to calculate nominal wave heights from boulder masses as a means to discriminate between emplacement mechanisms. Systematic review shows that this approach is based on assumptions that are not securely founded and that direct relationships cannot be established between boulder measurements and wave heights. A test using an unprecedented... |

| Large clastic cliff-top storm deposits (called CTSDs) are one of the most remarkable signatures that characterizes extreme storm wave events on coastal cliffs. Hence, the study of CTSDs is of key importance for understanding and predicting the impacts of extreme storm wave events on rocky coasts or establishing proxies for storm intensity. The present study uses new data including hydrodynamic measurements in both deep and intertidal waters, and records of CTSDs displacement and deposition across Banneg Island during the stormy winter 2013–2014. Two drone-based surveys were carried out in January 2013 (pre-storms) and in April 2014 (post-storms). In addition, complementary field observations were carried out during the winter, providing a comprehensive and... |

| The major objective of the present study is to demonstrate how remote sensing approach can be used for studying nearshore bottom morphology and shoreline changes in coastal Tanzania. Two study sites were used. In the first site, remote sensing satellite Landsat Thematic Mapper data was evaluated against known water depths from conventional echo sounding measurement taken on the eastern side of the channel. The correlation between the remote sensing data and the echo sounding mesurement was rather satisfactory, suggesting that the approach can roughly be used to investigate sea bottom morphology in the nearshore areas. In the second study site, remote sensing satellite data from Landsat Thematic Mapper and Enhanced Thematic Mapper were used to investigate... |

| En esta publicación se presentarán los elementos de morfología costera observados en la costa norte de la Península de Santa Elena. A largo plazo esta es una costa con alta variabilidad, pues estaba sumergida o compuesta por varias islas durante el cuaternario reciente (Pedoja, 2003). Dos preguntas básicas han sido planteadas en la ejecución de este estudio, la primera responder si esta alta variabilidad a largo plazo esta reflejada en la costa actual, y la segunda, si las morfologías costeras de plataformas litorales de abrasión son parte del proceso de la evolución costera. |

| Para el presente estudio de procesos costeros se han considerado los principales parámetros oceanográficos, se ha recopilado y obtenido información producto de algunos años de mediciones, de los cuales se obtuvieron las normales y tendencias de comportamiento. Se analiza toda la información y se aplican las ecuaciones correspondientes para el cálculo de los procesos costeros, mediante tres métodos distintos, propuestos por Galvin, Komar y Cerc, obteniendo valores que se comparan con el fin de establecer las diferencias basándose en la práctica y en estudios realizados con anterioridad. De acuerdo a los resultados y a los análisis realizados en las costas ecuatorianas, se deduce que el método más idóneo a aplicarse es el de Komar. Finalmente se analizan... |

| In Argentine coastal areas, geomorphological changes are directly related to relative continental uplifts and falls and to seaward and landward displacement of the coastline. Accretional and erosional phenomena are produced by displacement of the coastline in horizontal way. The resultant structures can be represented in two principal sectors. Backward motion or retrogradation of about 15 km were estimated for the Strait of Magellan, over an area of 500 km 2.Otherwise, large accretional phenomena were recognized in the north,with a 60 km seaward displacement, equivalent to 4,000 km2 in the last7.000 years. Variation in tidal regime and amplitude is reflected in the coincidence of the boundary between accretion and erosional sectors. Two principal nearshore... |

| La côte togolaise, basse et sableuse, soumise è une violente érosion par suite d'une série d'erreurs d'aménagements, a fait l'objet en 1987-1988 d'importants travaux destin's à protéger sur 15 km la ville d'Aného et l'usine de phosphates de Kpémé, principale industrie du pays. La préparation de ces travaux, de protection, rendus indispensables par la gravité des enjeux économiques et sociaux, a nécessité des études hydrologiques et sédimentologiques très détaillées, ainsi que la construction et l'exploitation par un bureau d'étude spécialisé de deux importants modèles physique (32 x 20 m) destinés à optimiser le dispositif de protection et à déterminer l'évolution du trait de côte sur une période de 25 ans... |

| The studies areas lay in Hurghada region include different aspects of coastal development. It represents different environmental problems and threats to the Red Sea ecosystem and geosystem. They include two tourist projects, a central marina for yachts and fishermen and a site for oil exploration and production. All sits have implemented Environmental Impact Assessment studies (EIA). Unfortunately, dredging and landfilling caused severe coast destruction and shoreline change in these areas. All sites have accurately surveyed and environmental problems cited, oceanographic parameters were measured, and 109 samples were collected from the beach and the tidal flat of four sits forming the study area. Grain size, carbonates and organic matter contents, major... |
