Sensitivity Analysis of Physiographic Parameters By Kinematic Wave Equation

Abstract

Sensitivity analysis of physiographic parameters describes the system behavior in terms Of mathematical equations representing the relationships between system state, input And output. The channel flow routing and overland flow routing are depending on Different kind of flow parameters. In this paper, the channel flow routing and overland flow routing for different kind of channel and overland flow parameters are discussed. The computer program for flow routing is developed in Lahey ED Developer. The results showed that the sensitivity of physiographic parameters through lumped kinematics wave models and found that the overland roughness and overland slope are more sensitive than other physiographic parameters of overland and channel flows.
