After reviewing status of India rivers, SANDRP presents an account of research, studies and important reports on erratic monsoon, climate change, floods which all are severely affecting the rivers, their aquatic life and livelihood of dependent communities.
Rivers and Monsoon
Number of rainy days falling across river basins in India The study has found that number of rainy days is falling across river basins in India and rainfall intensities are seen to be increasing. The analysis determined changes in heavy precipitation and peak flood for seven river basins in India—Krishna, Godavari, Mahanadi, Narmada, Cauvery, Sabarmati and Brahamani and Baitarani. For the study, data pertaining to daily flows for about 30 odd years and precipitation for 61 years (from 1951 to 2012) were analysed.
The analysis also said the rivers which flow from west to east direction (in India) have more rainy days compared to those which flow towards the west. The study also held that anthropogenic activities (construction of storage reservoirs, diversions, urbanization, land-use change, and soil and water conservation measures, among others) have probably affected the generation of peak floods in the rivers of India. http://www.livemint.com/Politics/c7v8oXmsMDHIldjDv9k6lK/Number-of-rainy-days-falling-across-river-basins-in-India-s.html (Live Mint, 27 April 2017)
