| Abstract | As part of the Deep Ocean Mission of the Ministry of Earth Sciences, INCOIS has prepared a report on the sea level rise and its extremes and also assessed the associated coastal vulnerability along the Indian coasts. It presents a comprehensive assessment of future sea-level rise and its implications for coastal India and the associated vulnerable maps for the 11 selected locations along the Indian coast. Using global climate models and probabilistic methods, the report projects that relative mean sea levels (RMSL) along the Indian coastline could rise by 0.62 m (Visakhapatnam) to 0.87 m (Bhavnagar) under SSP5-8.5 (high emission scenario) by 2100, whereas extreme sea levels along the Indian coasts and islands are projected to rise between 0.68 m (Chennai) and 1.12 m (Bhavnagar). Further, Indian coastal regions north of 13N are seen as more vulnerable to extreme sea-level change, with the Gulf regions off Gujarat and the northern coasts of the Bay of Bengal experiencing the largest changes in tidal maxima and climate extremes. |
