| Research Abstract |
Probabilistic flood envelope curve was derived on the basis of relationship among rainfall depth, area and duration (DAD relationship) of spatially distributed rainfall data, that is radar observed rainfall data and generated data by regional climate model (RCM) developed by Japan Meteorological Agency. The results show that 200-year flood envelope curve envelopes record maximum specific discharges in Yoshii River Watershed in Okayama, and that flood discharge will be increased in the future and increasing rate will be raised by the size of a catchment at 100 years from now.
