Abstract
As part of a wider study of the Betwa basin, central India, estimates of rainfall, potential transpiration, soil moisture and groundwater storage, and river flow are available for the Nion catchment in 1978 and 1979. These show that net rainfall is divided between soil moisture storage, groundwater storage and runoff in a sequence which is similar in 1978 with rainfall above average and in 1979 when rainfall was well below average. The knowledge acquired in process studies is incorporated in a conceptual model which reproduces reasonably not only the runoff but also the water stored in the catchment.
