Abstract | A nonlinear, deterministic, lumped parameter model for synthesizing hydrographs by channel routing is developed , which is equivalent to the solution of the kinematic channel routing without lateral inflow . Model building is based on the numerical solution of the kinematic wave equations in a single reach , given a triangular inflow at the upstream; the structure of the existing storage routing model is found to be inadequate to describe the hysteretic effect of a storage-discharge relationship. A four parameter storage function model developed herein was calibrated to kinematic wave solutions with varying the parameter value sets for several triangular hydrographs; the model parameters were identified using an optimization technique . In the verification process, the storage routing parameters are correlated with the kinematic wave parameters as well as geometric parameters of inflow hydrographs at the upstream boundary. The proposed model makes the runoff routing procedure considerably more useful than a kinematic routing and yet maintains the same physical and hydraulic characteristics and saves much computer time and effort |
