Coastal zone is a very multi-faceted, energetic and fragile environment because of the influence of both terrestrial and marine ecosystems. Majority of the world�s coastlines are experiencing a wide range of anthropogenic and natural pressures. Anthropogenic threats are the consequence of rapid urbanization, population growth, tourism activities, harbor development, industrialization, over-exploitation of natural resources, waste accumulation and environmental pollution. On the other hand, natural pressures are mainly from sea-level fluctuations and climatic anomalies. This paper mainly focuses on coastal erosion hazard assessment estimated along the coastal precinct between Kanyakumari and Mandapam, southern Tamilnadu coast over a length of about 360 km. Risk assessment was carried out based on the type of coastal erosion indicators found along the shoreline and general spatial distribution of coastal erosion indicators along the investigated area. Results reveal that the study area is under the treat of coastal erosion with high-risk category.
