Morphological changes along Bangladesh coast derived from satellite images

Being a low laying deltaic country, the morphological changes of the coastal zones of Bangladesh become a major social, economic and environmental concern. In this study, images of Landsat satellite during 1989-2010 are analyzed to detect the variation of shoreline positions. The western-central coast has been divided into different segments and changes have been observed in the south face. Shoreline change rates have been analyzed for two period 1989-2000 and 2000-2010. Every segment has been facing more changes in the previous decade 1989-2000 as compared to the recent decade 2000-2010. Segments covered with mangrove are facing more changes compared to flat sandy beach which is contradicting with general consensus that mangrove stabilize the land.
