oblivious to the obvious solution: Trees! Trees are smart enough
to allow water to fly defying gravity like all living beings do!
Look at the India Meterological Department(IMD) data and get to know
how to use it smartly. From fundamental physiological properties
of plants, it follows that a tree transpires its own weight of water
in a day. At 10 kg/sq.m dry biomass weight, in 41 days from June 1,
the transpiration by the sucking action of the sun on a square meter
of land amounts to 0.41 cubic meters. The IMD data for cumulative
rainfall till 11 July 2016 is 267.7 mm. On a square meter of India, the
cumulative rain till 11th July is 0.2677 cubic meters! So the solution
for floods and droughts is NOT DAMS but ecological reforestation using
people's cooperatives for the next millennia, A la Ashoka! See
