Floods are one disaster with a higher incidence rate than other disasters. Floods have a very significant impact on human life around the world. Floods can also cause social conflicts and conflicts of interest, environmental problems, and economic effects. Therefore, the spatial and temporal study of flood dynamics is essential in water resources management and disaster risk reduction. This study aims to develop a hydrological spatial model to predict discharge for flood risk reduction in the Wanggu Watershed, Kendari City. The model used in this study is Hec-HMS with the calculation of the Gridded SCS Curve Number loss method, ModClarck transform, and Recession method for baseflow calculations. The model calibration uses a measured discharge with statistical parameters Nash Sutcliffe (NSE) and PBIAS. The results showed that the spatial model for predicting outflow in the Wanggu watershed reached the optimum condition at a recession constant of 0.95. The result shows that the spatial model can predict peak outflow and time with high accuracy based on statistical parameters NSE 0.72 and PBIAS 0.17%.
