Coastal geomorphic features around Indian Ocean

Coastal areas are important globally. These areas have also drawn attention of geomorphologists for in-depth studies. Several institutions have made contributions towards analysis, identifications of different geomorphic features and their mapping. Attempts have been made to map oceans and associated coastal geomorphic features. In this paper an effort has been made for the Indian Ocean. There are straits, channels, continental sub-marine margins and continental shelf which form different components of the coastal ocean. They are shaped by land erosion, sub aerial deposition, volcanic, diastrophic, marine erosion and deposition and organisms. The interactions of these features are so variable that the coastal features are almost infinitely complex. The coasts of Indian Ocean realm fall into more than one category. Therefore, a matrix reference can be used with definite colour band to depict each single or compound feature.
