Water Resource

 

 River Basins & their catchment areas

River basin is considered as the basic hydrological unit for planning and development of water resources. There are 12 major river basins with catchment area of 20000 km2 and above. The total catchment area of these rivers is 25.3 lakh km2. The major river basin is the Ganga-Brahmaputra-Meghna , which is the largest with catchment area of about 11.0 lakh km2 (more than 43% of the catchment area of all the major rivers in the country). The other major river basins with catchment area more than 1.0 lakh km2 are Indus, Mahanadi, Godavari and Krishna. There are 46 medium river basins with catchment area between 2000 and 20000 km2. The total catchment area of medium river basins is about 2.5 lakh km2. All major river basins and many medium river basins are inter-state in nature which cover about 81% of the geographical area of the country.
