Deterministic modelling of annual runoff and sediment production rate for small watersheds of mahi catchment

Multivariate statistical techniques have been applied to develop dimensionally homogeneous and statistically optimal models for prediction of annual runoff and Sediment Production Rate (SPR) from the small watersheds of Mahi catchment. The dimensionless geomorphic and rainfall parameters have been used as independent variable in the analysis. The significant components and parameters have been obtained by applying principal component analysis. The validation of the models has also been done. The developed models can be conveniently used to predict the runoff and SPR of small ungauged watershed of Mahi catchment having similar physiographic characteristics.
