Abstract :
The coastal zone has become one of the most important activity zones in the world as it is thickly populated and has several industries and other establishments. Development activities in the coastal zone must be systematic within the framework of well-defined Coastal Zone Management Plans. Thorough understanding of coastal processes which are controlled by coastal hydrodynamics and the resulting sediment transport is essential for development of coastal zone management plans. The study of these processes can help in developing appropriate strategies for coastline management and conservation. This study has been conducted at Thiruvananthapuram coastal stretch (78km) for wave analysis and estimation of longshore sediment transport. Dedicated wave model has been developed using MIKE 21 SW model and the simulated wave climate has been used in LITPACK model for estimation of sediment transport which is calibrated and validated with the real data. Study has conducted from 2013 to 2022 during south-west monsoon season. Study shows that the Thiruvananthapuram district seashore experiences significant longshore sediment transport, with sediment moving predominantly towards the south during monsoon season with gross sediment transportation of 1.34×106m3
