Abstract | Shoreline is one of the constant shifting features in coastal region. Frequent detection of shoreline changes is crucial to recognize dynamics of distinct coastal landforms. In present study, shoreline changes during last 30 years (1991-2021) have been detected using Digital Shoreline Analysis System (DSAS) tool and Multi-dated satellite datasets (Landsat 5 TM, Landsat 7 ETM+ & Sentinel-2) with interval of 10-year from the 1991 to 2021. The study area is the innermost northeast part of Gulf of Khambhat spreading over approx. 12 km from Kamboi to Dehgam. Total 115 transects were laid at a distance of 100m each. The result shows, highest erosion rate for End Point Rate (EPR), Linear Regression Rate (LRR) and Weighted Linear Regression (WLR) to be -40.24m, -49.33m, -49.33m, respectively at transect no 84. The forecast of shoreline position for the year 2032 & 2042 were observed through Kalman Filter Model and found that there will be erosion of approximately 444m in the next decade for the same transect which will increase about 989m till the year 2042. However, on the other transects, the future projections of erosion are comparatively lower for 2032 and 2042. The study, therefore, indicates probable erosional potentials in this area. |
