| Summary: | Sustainability requires that once reservoirs are built, they should be managed as environmentally friendly as possible. If the management policy does not achieve efficiency, there might be a man-made disaster occurred. There is a need for establishing a national strategy for developing hydrological forecasting techniques. In this study, hydrological models MARINE and SWAT were established for the Ban-Chat reservoir basin by testing performance in simulating hourly inflow during flood season for short term forecast and daily inflow for long term management respectively. Both models are set up using the same available database but they differ in terms of spatial discretization, infiltration and water redistribution representation and river flow transfer. Overall, it is argued that MARINE is well presented in forecasting real flash flood events in a short period of time, while, SWAT model is suitable to predict the impact of land management practices over long periods of time. This paper describes a simple, direct approach to the reservoir management and analysis of flood discharge. |
