Question

short note aboutground water in india

Answer 1

India has vast ground water resources. The average rainfall over the country is about 110 cm as a whole and this rainfall over India's area of 328 million hectares gives a total precipitation of 3700 billion cubic metres. Only 22 per cent of this total rainfall percolates under the ground. Of this total amount about 430 billion cubic metre reaches upto the upper surface of the soil. Remaining 384 billion cubic metre reaches the pervious strata which could be obtained by dugging the well. But only 70 percent of this amount can be exploited economically
