Analysis of Nearshore Profiles Off Paradip Port, East Coast of India

Abstract

Sediment movement in the nearshore zone off Paradip has been studied in relation to sediment supply, harbour siltation and shore erosion. Estimates of erosion and deposition have been made at different cross sections along the coastline with the nearshore profiles. The effectiveness of the sand pumping and hoppering into the offshore area in safeguarding the beaches has been discussed. The nearshore profile data presented in this paper indicate that the active zone for initiation of sand movement by waves and bottom currents is even beyond 14 m depth. It has been-well supported by the rapid advance and retreat of the bottom contours starting from 3 to 14 m depths off Paradip.
