Flood routing in the catchment area can be simulated by transform method. Based on the complexity of data requirement, there are two significant differences of the transform method in watershed routing, namely the SCS Unit Hydrograph and Kinematic Wave. The purpose of this study is to analyze the effectiveness of those two methods by comparing two hydrographs using HEC-Geo HMS on Urban and Rural Watersheds. Comparison has been simulated by calculating the ratio of peak hydrograph discharge to each calculation condition and the level of hydrograph compatibility. Another possibility to analyze the effectiveness of two methods by plotting accumulative discharge values from the two hydrographs produced by the SCS Unit Hydrograph method using the Kinematic Wave method. The results of the hydrograph comparison indicate that Kinematic wave method which requires more detailed data more suitable for Urban Watershed than SCS Unit Hydrograph. However, for the Rural watershed, SCS Unit Hydrograph shows satisfactory result.
