Distribution of longshore sediment transport along the Indian coast based on empirical model

Abstract

An empirical sediment transport model has been developed based on longshore energy flux equation. Study indicates that annual gross sediment transport rate is high (1.5 x 10 super(6) cubic meters to 2.0 x 10 super(6) cubic meters) along the coasts of south Orissa, north Tamilnadu, south Kerala, north Karnataka and south Gujarat, whereas it is comparatively less (0.5 x 10 super(6) cubic meters to 1.0 x 10 super(6) cubic meters along the south Tamilnadu coast. Coast between Pondicherry and Point calimere in Tamilnadu, and Maharashtra coast experience negligible quality of annual net transport. The direction of annual net transport along the east coast is in north and along the west coast in south except at south Gujarat coast
