WATER RESOURCES DEVELOPMENT & UTILIZATION IN WESTERN INDIA ARAVAZHI.T BTE
Indias Water Budget Annual precipitation km3 Annual flow per year for the Indian rivers km3. Annual replenishable groundwater resources -432 km3 Annual utilizable surface water 690 km3 per year Annual groundwater resources 396 km3 per year Cherrapunji -Highest Rainfall in the world
Major Rivers Of Western India Name of the RiverLength(km)Catchment Area(sq km) Sabarmati Mahi Narmada Tapti Mahanadi Godavari
Basin Wise Average Flow And Utilizable Water Name of the RiverAverage annual flow (km³/yr) Utilizable flow (km³/yr) Sabarmati3.81 Mahi Narmada Tapti Mahanadi Godavari
Rainfall Conditions Annual rainfall of less than 500 mm is experienced in western Rajasthan and adjoining parts of Gujarat. Some parts of Western Rajastan receives annual rainfall of less than 100 mm. Nearly 80 per cent of the land in the Konkan, which receives the highest rainfall on the West Coast.

Recharge Of Aquifers In western indias unconfined alluvial aquifers, it is being increasingly realized that groundwater depletion can be countered only by importing surface water. Sardar Sarovar Project (SSP) The purpose of the project is to identify reliable sources of water of sufficient quantity and quality to supply.
