Water has demand from growing population
The availability of water is unequal – because of physical and climatic diversity
Problem - need solve by micro level planningWater - Soul of Nature
Available water for planed use – 38882 million m³ in Godavari Basin total use upto 1996 = 17969 million m³ demand will growth upto 2030 = 43446 million m³

Ground Water Level decreasing - (Ahemadnagar, Aurangabad and Nashik District)
Surplus & Deficit Region
Though, the Irrigation, Industry and Urban Sectors in Maharashtra is one of the largest in the country, but they facing the water availability problem from last few decade.
Similarly, the water availability for future use of population, urban area, irrigation, industry has been reducing at a fast rate.
This situation has been responsible for rising problems and vulnerable situation in the present area.
How we can solve the water problem ?
Running
• Conversion of water
from Saline to Fresh– But need high budget and technology
Water Conservation- Activity going on in IND
Rainwater harvesting
Discussion
Water Diversion-Himalayan River- South IndiaW. Ghats - Drought prone Area Need Detail Survey with RS
& GIS techniques.
RS & GIS has high potential for searching the water diversion sites within short period, and high accuracy.
