The shoreline is a multifaceted feature of the Earth’s surface and is highly susceptible to both natural and anthropogenic influences. Hence, accurate and frequent shoreline change monitoring is essential for determining the dynamic nature of coastal areas. This paper highlights the shoreline changes in the Gujarat coast from 1993 to 2023 with 10-year interval multitemporal Landsat satellite datasets. The modified normalized difference water index was used to extract the shoreline by differentiating the land-water boundary. The shoreline change rates were calculated by applying statistical techniques, such as the end point rate, linear regression rate, net shoreline movement, and weighted linear regression, using a digital shoreline analysis system. In this study, a total of 8782 transects were employed on the considered coastline stretch at an equal distance of 100 meters. Almost half of the transects (49.7%) showed an accretion trend, while erosion was observed in 23.6% of the transects. The remaining 26.7% of transects were in stable condition. This study was performed on a regional scale with significant detailed information that can help further research on sustainable coastal zone management and planning.
