Abstract:This paper is aimed at the development and implementation of an ensemble flood forecasting system in Taiwan. This system features providing the ensemble flood forecasts with 3-hour lead time in a near real-time manner. Four sets of flood forecasts can be obtained at once for the ensemble analysis. A weighting method for ensemble average is proposed to improve the accuracy of the forecasting water levels in this study. The flood event caused by Typhoon Sinlaku in Tamsui River basin is taken as an illustrated example. Due to the flash flood characteristics, the ensemble forecast with 3-hour lead time does provide the officials more responding time for flood hazard mitigation. On the other hand, in order to help the authorities using decision support systems (DSS) effectively, a human-centered, open and virtually integrated platform for the use of heterogeneous DSSs is proposed. Via this virtual platform, the officials, experts and scholars at different locations can easily share their DDSs' information and communicate and discuss immediately. Finally, an application example associated with a flood event has been carried out to demonstrate the applicability of the proposed system and platform. The result shows that the real-time monitoring, the water-level forecasting, and the spatial geographic information are very crucial and can be obtained immediately in this application. Therefore, the potential usefulness and benefit of the systems and platforms has been recognized.
