Estimation of runoff and soil loss for a hilly watershed

摘要

Estimation and analysis of rainfall-runoff-discharge data for a watershed would be of great use for optimum planning and managing the watershed. Universal Soil Loss Equation (USLE) was used to estimate the annual soil loss from a hilly watershed in the Nilgiris. A Set of linear regression models were developed by relating (1) rainfall and runoff, (2) rainfall and soil loss and they can be used for prediction of the runoff and soil loss for the watershed. Packages of soil and water conservation measures were rccommendd for the watershed as the present runoff and soil loss wre found to be enormous.
