| Research Abstract |
This study developed a new model to predict river discharge and flood inundation simultaneously and simply for any river basin in the world. The model is named Rainfall-Runoff-Inundation(RRI) model, which has been applied to a various flooding in the world during this study period. Particularly, for the devastating 2011 Chao Phraya flooding in Thailand, an emergency response-type flood prediction conducted in mid-October 2011 indicated that the large-scale inundation in the lower part of the basin might remain even until the end of November. The post flood analysis with field investigations verified that the above prediction was more or less reasonable, and updating various input information including evapotranspiration showed significant improvement in terms of simulating more accurate river discharges and inundation depths.
