ABSTRACT

The morphometric changes in coastal landforms can be related to the seasonal and spatial variation in wind velocity, wave energy, storm surges, and cyclonic phenomena along the coast of India. The west coast is marked with a broad and shallow continental shelf. It is subject to high storm surges, but smaller waves along the coast of Karnataka and Kerala in early monsoons, maximum morphological changes take place with high wave energy. During this period, most of the sediment material gets transported along the shore and gets preserved during the post-monsoon season. The gross sediment transport is low (5x105m 3 ) along the west coast. While, the east coast of India with a narrow and steep shelf, produces high and powerful waves. Rivers, along their mouth region, discharge water and sediment explicitly as well, higher along east coast. The northeast monsoon brings high wave activity along the east coast, increasing the rate of sediment transport (15-20 x105 m3 ). Meanwhile, the stretches of the east coast are subjected to severe storm surges and cyclonic storms during OctoberDecember. The calculated wave energy spectrum was used to identify the different wave systems present in the study areas. The present study determines the distribution of wave energy along the Indian coast and the associated coastal conditions.
