Abstract
Sea-level rise being one of the most significant effects of climate change have grabbed the attention of the world. Although the exact forecast of rise of sea level remains uncertain, many projections for high emission scenarios from individual studies were found much greater than likely range of 1 m of the 21st century SLR given in AR5 of IPCC. Moreover, due to the additional load from melt ice the Sea Level Rise is escalating in recent years. As per IPCC AR5 (Special Report on Emission Scenarios) climate simulator model at local level SLR at Mumbai coast is 1.24 m, 0.94 m, 0.81 m above MSL under RCP 8.5, RCP 4.5 and RCP 2.6 respectively. Vulnerability of Mumbai to Sea Level Rise ranks 2nd amongst 136 coastal cities in the world, while Guangzhou (in China) tops the list and next to Mumbai is New Orleans (in Louisiana, USA). Mumbai being a very old reclaimed city with antique drainage system is flood-prone in monsoons. Being the Financial Capital of India further inundation arising out of Sea Level Rise is a matter of grave concern. In this paper the expected Sea Level Rise at the coast of Mumbai in 2050 has been attempted to be determined by the climate change tool using Grinsted’s method with the help of Mike 21 FM HD Software, the state-of-the-art software from Danish Hydraulic Institute and the probable consequences has been presented.
