Rainfall-Runoff-Inundation Simulation Based on Global Hydrologic Model Nesting

这项研究开发了一个新的模型，可以同时简单地预测世界上任何一个流域的河流流量和洪水淹没。该模型被称为降雨-径流-淹没(RRI)模型，在本研究期间已在世界范围内的各种洪水中得到应用。特别是2011年在泰国发生的湄南河洪灾，2011年10月中旬进行的紧急响应型洪水预报表明，流域下游的大规模洪水可能会持续到11月底。洪水后分析和实地调查验证了上述预测的合理性，更新了包括蒸散量在内的各种输入信息，在模拟更准确的河流流量和淹没深度方面有了显著改善。

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.
