| Abstract;A real-time distributed flood prediction system is developed for the Yodo River basin (7,281 km'2'). The system provides 6 hrs-ahead predictions every hour. The predictions include dam reservoir inflows, outflows and reservoir stages located in the catchment and 1,707 places of river discharges at about 3 km intervals along the channel networks shown on 1:25000 topographic maps. Topography of the watershed is modeled with 250 m grid DEMs and water movement of mountainous slopes and rivers are routed using the kinematic wave model. To drive the prediction system, 6 hrs distributed rainfall prediction with 2.5 km grid resolution provided from the Japan Weather Association and the Japan Meteorological Agency is used. The interactive real-time web-based data displaying system is also developed. (author abst.) |
