A Shoreline Change Detection (2012-2021) and forecasting Using Digital Shoreline Analysis System (DSAS) Tool: A Case Study of Dahej Coast, Gulf of Khambhat, Gujarat, India

Shoreline is one of the coastal landforms which continuously changing in nature. Hence, monitoring shoreline change very obligate to understand and manage process. The objectives present study were i) identify detection (2012 2021) based on various statistical methods along Dahej coast, Gujrat. ii) forecast position after 10 years. DSAS tool Multi-dated satellite images (Sentinel-2 LISS-IV) used study. result shows that, pattern rate was more or less similar with little variation values for 3 different methods. Highest erosion End Point Rate, Linear Regression Rate Weighted found -33m, -31m, -31m respectively at transect no 54. accretion 38m (EPR), 50m (LRR), 51m (WLR) a particular transect. year 2032 observed through Kalman Filter Model. Seasonal analysis years (2016, 2017, 2018) region not having any seasonal pattern.
