The coastal zone is exposed to different cyclic and random processes that continuously undergo changing the region. It is essential to understand the coastal processes of erosion, transport, and deposition of sediments for sustainable development of the property and natural habitat. The coastline on either side of the Indian peninsula is subjected to varied coastal processes and anthropogenic pressures. Accurate prediction of the sediment transport, caused by waves and tidal or wave-induced currents, is of great importance in predicting coastal morphological changes. In the present paper, the land-ocean interaction processes and regional coastal issues such as erosion, suspended sediment transportation, etc are studied and reviewed with the synergetic application of in situ, remote sensing, and numerical simulation methods.
