The risk assessment model for dam and levee is applied to a river where two adjacent dams are located in the upstream of the watershed. "A" dam is proven to be safe with 200-year precipitation and unsafe with PMP condition. Whereas "B" dam to be safe with 200-year precipitation and PMP condition. The computed risk considering the uncertainties of the runoff coefficient. initial water depth and relevant data of the dam and spilway turn out to be equivalent results in Monte-Carlo and AFOSM method. In levee risk model. this study addresses the uncertainty of water surface elevation by Mannings equation. Monte-Carlo simulation with the variations of Mannings roughness coefficient is calculated by assuming that it follows a triangular distribution. The model can be used for preparing flood risk maps. flood warning systems, and establishing nations flood disaster protection plan.
