Clean water in floods (WIF)

Climate change is said to have in part caused (but may also be a natural evolution of earth's cycle) large-scale floods across central India, including the Mumbai floods of 2006 and 2017. During 1901-2015, there has been a three-fold rise in widespread extreme rainfall events, across central and northern India - Gujarat, Maharashtra, Madhya Pradesh, Chhattisgarh, Telangana, Odisha, Jharkhand, Assam and parts of Western Ghats - Goa, north Karnataka and South Kerala.[14] The rising number of extreme rain events are attributed to an increase in the fluctuations of the monsoon westerly winds, due to increased warming in the Arabian Sea. This results in occasional surges of moisture transport from the Arabian Sea to the subcontinent, resulting in heavy rains lasting for 2-3 days, and spread over a region large enough to cause floods.
