| Outline of Final Research Achievements |
Cumulonimbus clusters as many as 3150 were generated, and rainfall in longer durations exceeded the historical records at many points in the upper reaches of the Kinu River. The embankment of Kinu River breached, and the maximum inundation volume on the inundation area of which ground had been subsided was 38 million m3. Because of the direct damage to paddy field crops and the difficulty in draining flood water, the importance of considering sediment deposition was pointed out. The issuance of heavy rain emergency warning was effective in establishing task forces at municipalities, and the hotline to the municipalities from river administrators worked effectively for decision making. Since synthetic judgment of large to small river was required, sharing both realtime and forecast water level, importance of improving knowledge about flood disaster process of citizens along river was pointed out.
Thus, the integrated browser for flood disaster timeline has been developed.
