Description 1281-1285
In the
present study, the coastline change analysis of South
Gujarat along the west coast of India has been taken up for a detailed
investigation. Historical satellite imageries from Landsat ETM+ are used to
estimate the positions of the shoreline along this stretch of the coast, for
various years. A finite-difference based numerical model was also setup for the
selected coastal stretch to estimate the shoreline changes. The coastlines
extracted from the first few satellite imageries are used to calibrate the
numerical model, where as the rest are used to validate the numerical model.
Based on the numerical model, attempt is also made to predict the fate of the
coastline in the near future. An average erosion rate of about 4 m/year is
estimated along the South Gujarat coastline. It is also observed in the
predicted coastlines from 2018 to 2033 the average erosion ranges from 32.55 m
in 2018 to 61.79 m in 2033. The details of the data, numerical model and
analysis are presented in this paper.
