| Abstract: | Hope Island is a long spit formed in Kakinada Bay, India. It acts as a barrier to direct sea currents thus protecting Kakinada town, port and mangroves along the coast. Erosion was noticed at one section of the Island on visual interpretation of IRS-ID LISS-III imagery. In the absence of sea depth data it was difficult to analyse the extent of erosion along the height of the Island above the seabed. Remote sensing based bathymetric estimates were made and used to investigate the erosion problem at selected locations. The work considered the use of remote sensing for determining three-dimensional coastal erosion along slopes of Hope Island. |
