USE OF GEOMORPHOLOGICAL PARAMETERS FOR SEDIMENT YIELD PREDICTION FROM WATERSHED

Abstract

The watershed parameters which represent its morphology were grouped under four different categories viz. Steepness component, Shape component, Drainage component and Geologic component. In the present study, judiciously selected representative parameter from each group was mathematically associated with runoff rate to develop a multiple regression equation for sediment yield prediction. The sediment yield model thus developed was validated using non parametric statistical test for a data set of Banha Watershed in the Upper Damodar Valley (UDIO, Chotanagpur plateau, Bihar
