Monitoring Shoreline Changes in the Gulf of Khambhat, India During 1966–2004 Using RESOURCESAT-1 LISS-III

Abstract

This paper provides an assessment of the shoreline changes, which occurred during 19662004 in the coastal regions of the Gulf of Khambhat using RESOURCESAT-1 LISS-III (Linear Imaging Self Scanner) data. The remote sensing observations of the Gulf show a large area facing a serious threat due to dramatically changing shorelines. The entire coast around the Gulf has undergone accretion except some parts of the northern region and a few areas near the Mahi and Dhadhar estuaries where erosion is observed. These significant landform changes have occurred in four decades. The study has also shown the potential of the enhanced radiometric resolution satellite remote sensing data to be utilized for preparing good quality cartographic maps with improved shorelines leaving behind old maps prepared using conventional geodetic/ground surveys. The detection/quantification of shoreline change in the Gulf of Khambhat using advanced/latest models is proposed as an avenue of further research.
