Investigating Muskingum-Cunge Method Application of Different Schemes in Flood Routing

Abstract

Wave flood is the one kind of gradually varied flow. Flood prediction and flood control are very significant; therefore, one of the essential factors in design and evaluation of hydraulic structures and water resources planning is the prediction of flow discharge in rivers which is done by flood routing operation. Muskingum cunge is classified under hydraulic routing categories. This method has been used for modeling unsteady flows. Since this technique has sufficient accuracy, it does not need recorded data. In this study, in addition to the description of constant and variable parameters Muskingum-cunge method, the results were compared by numerical solution included kinematic wave using HEC-RAS software and dynamic model using Mike 11. Results represent that Muskingum-cunge method surely can be used for flood flow routing in rivers.
