Which basin has highest water availability?

a. Brahmaputra/Barak Basin

b. Godavari/Krishna Basin

c. Ganga Basin

d. Ganga and Brahmaputra/Barak Basins are at the same level

ANSWER: Brahmaputra/Barak Basin

Explanation:

There is a wide disparity in basin-wise water availability due to uneven rainfall and varying population density in the country.

The availability is as high as 14057cu m/year per capita in Brahmaputra/Barak Basin and as low as 307 cu m/year/person in Sabarmati basin.

Ganga basin has around 1061.74 cu m/year/person and Godavari basin has 1486.01 cu m/year/person availability.

Any situation of availability of less tan 1000 cu m per capita is considered by international agencies as scarcity conditions.
