概要

西ベンガル州スンダルバンのサーガル島周辺地域の海岸線の変遷

ラウプ・カーン

Sagar Island has occurred in many places from 2000 to 2016. There is a clear evidence of decreasing land area of inward shifting of shore line. The changes occurred by erosion due to sea level rise but some places deposition occurred by river and wave. Due to continuous sea level rise and low height of Sagar Island, sea level has been entered toward land. Average height along the coast is less than 2 feet and average height middle position of the island is 15 feet but some places height less than 4 feet and some places height more than 20 feet. We measure height of the some places and based on this height and Google earth image we draw contour line on the Sagar Island.
