Reply to Discussion of 'Application of Excel Solver for Parameter Estimation of the Nonlinear Muskingum Models' by Farzan Hamedi, Omid Bozorg Haddad, and Hosein Orouji

摘要

First of all, the author thanks the respected discussers for the useful comments on the original paper. However, the following clarifications and responses are necessary. As mentioned at the end of "Results and Discussion" section of the original paper, the main object of the original study was the evaluation of the Excel solver as efficient, simple and convenient tool for parameter calibration of the nonlinear Muskingum model through the benchmark problem of Wilson (1974). In other words, the original paper focuses on the hydrologic parameters calibration of the of the Muskingum flood routing model. Therefore, the same numerical solution method was used to compare the results with other parameter estimation algorithms. Based on the results of the original paper, the Excel solver was a promising approach to reduce problems of the parameter calibration of the nonlinear Muskingum routing procedure.
