Abstract

Flood routing is needed to determine the distribution of flood peak time and magnitude of peak flooding that occurs. Flood routing can be done on the river channel using the transform function principle. There are two methods of flood routing in reach that have significant differences based on general concepts and number of data requirements needed, namely Muskingum-Cunge method and Kinematic Wave method. This study aims to evaluate the efficiency of two flood routing methods, Muskingum-Cunge method and Kinematic Wave method using HEC-Geo HMS, the efficiency of each routing method is obtained from comparison of simulation's hydrograph peak discharge. results with the observation's hydrograph peak discharge. Results of the comparisons show that Kinematic Wave method give a large peak discharge which is closer to the observation than simulation results with Muskingum-Cunge method. However, difference of result from two methods are not too far from observation, although Kinematic Wave method uses more detailed data. Based on these results, it can be concluded that Muskingum-Cunge method is more efficient than Kinematic Wave method in conducting flood routing because it provides a hydrograph that is close enough to fewer data requirements.
