Abstract

The study of satellite images of 2001, 1999, 1997 and topo-sheet of 1975 indicate a widened channel of Nilarevu at its mouth and an erosional shoreline on the northern bank. The spit on the southern side has grown and added another curved spit to its distal end. The beach ridges are aligned with the curved spit. The accreted river mouth bar off Gautami till 1975, rapidly got eroded simultaneously nourishing the spit at the mouth of river Nilarevu. The change in the shoreline configuration during 1975 to 2001 is conspicuous.
