Longshore sediment transport along the Indian coast

Abstract

An empirical sediment transport model has been developed based on longshore energy flux equation. Ship reported waves, publised in Indian Daily Weather Reports, are compiled for 19 y and used for estimation of sediment transport. Annual gross sediment transport rate is high (15-20 x 10(5)m3) along the coasts of south Orissa, north Tamilnadu, south Kerala, north Karnataka and south Gujarat, whilst, it is comparatively less (5-10 x 10(5)m3) along the south Tamilnadu coast. Maharashtra coast and the part between Pondicherry and Point Calimere in Tamilnadu, show negligible order of annual net transport. Annual net transport along the east coast is in north and along the west coast in south but for south Gujarat coast.
