摘要：Watershed is an hydrological unit. The physio-hydrological behaviour of the watershed is studied by using the hydrologic modelling. Watershed proper scientific planning and management needs reliable detailed data for reliable predictions. In the study the multivariate statistical method is applied to development of dimensionally homogeneous and statistically optimal models for prediction of annual runoff in the selected watersheds in upper and middle sub basins in Godavari basin. The Principal component analysis (PCA) technique is applied in order to group similar geomorphological characteristics and to screen out the least importance parameters. The deterministic annual runoff model is developed on the basis of the geomorphological characteristics and annual rainfall and runoff data. The model is also validated. The developed models can be used to predict the annual runoff for upper and middle sub basins of Godavari basin. The developed model can be used to predict the annual runoff having similar hydrological conditions.
