5-Sensitivity Analysis of Two Watershed Models Applicable in wet Mountainous Areas

Abstract

Parametric sensitivity analysis of two watershed models developed for application in the Western Ghat areas has been carried out. The models being complex, a numerical approach has been adopted for the analysis. Data from three catchments in the Malnad areas of Karnataka has been used to check the importance of the various parameters in the two models. It has been found that the model simulations are highly sensitive to the parameters in the equtions for pipe flow and delayed flow.
