Abstract

Gen Expression Programming is the newest method of evolutionary algorithm methods that because of the sufficient accuracy, has more application. GEP using the information in the data and without any assumption on the structure of the relationship between independent and dependent variables identifies an appropriate relationship and predicts the output hydrograph. DYNAMIC WAVE method is one of the complicate methods in FLOOD ROUTING and because of the need to hydraulic and cross section data routing by this method is costly and time-consuming. In this study a computer model has been developed in which partial differential equations of unsteady none uniform flow, are solved by staggered method. This model can consider infiltration into river bed. Statistical indicator such as Coefficient of Correlation(R), Mean Absolute Error (MAE), Mean Square Relative Error (MSRE) and Relative Error (RE) are used to comparison two methods. The results of routing of 6 events between 1384 and 1388 indicate that performance of GEP model to predict the volume of output hydrograph is better than DYNAMIC WAVE model. While, the ability of DYNAMIC WAVE model to predict hydrograph peak flow and time of peak discharge is more reasonable than GEP model. Hydrograph peak flow discharge is calculated by DYNAMIC WAVE model with 7.25% mean error and GEP model predict it with 17% error. Also mean error for prediction of time of peak discharge is 1.45% and 2.25% by mentioned models respectively.
