All the watersheds cannot be gauged, as it would be costly and time consuming. Therefore,
the indirect method of runoff quantification has to be resorted. For predicting runoff from the known
causative factors, it is important to include topographic or geomorphic characteristics which reflect directly
or indirectly on climate, geology and transportation processes from the watershed. In the present study ten
watersheds from Tapi catchment of Maharashtra state, India were selected for development of geomorphic
response models for prediction of annual runoff. Twelve geomorphic parameters were selected for
development of model out of which two parameters, Sa and Rb were screened out in the PCA and remaining
ten parameters were grouped into three physically significant components. Developed annual model when
validated, it was observed that percentage deviation was within 10 per cent. Therefore developed annual
runoff can be conveniently used for prediction of annual runoff from unguaged watersheds of the basin
having similar physiographic conditions for design of different water harvesting structures
