Flood routing in rivers is a mathematical process. Its purpose is determination of downstream flood hydrograph. Solving the complete Saint-Venant equations for unsteady flow analysis is generally complicated. For this reason, the use of computer and developed commercial models is necessary. In contrast to these complicated methods, different simplified and approximate procedures of hydraulic and hydrological flood routing have been developed. These procedures with taking into account of some assumptions are capable of flood routing in rivers. In this research, the accuracy of two approximate methods of flood routing including Kinematic Wave and Muskingum-Cunge procedures in a case study in Doab Samsami river were considered and compared to each other. Results show that RMSE values for Kinematic Wave and Muskingum-Cunge methods are 0.845 and 1.401, respectively. In general, results obtained indicate that Kinematic Wave model is more accurate than Muskingum-Cunge model.
