The catchment area for the sub-basins is the area between the gauging station and the nearest upstream gauging stations, and does not include the entire catchment area. (Ref : Closing of the Krishna Basin: Irrigation, Streamflow Depletion and Macroscale Hydrology, Research Report 111. IWMI)
Change in rainfall, runoff, and runoff coefficients for two time-periods, 1971-1974 and 1996-2001.
