In recent years, due to the impact of the growing local heavy rains, unpredictable urban flood is increasing rapidly. Meanwhile, the calculation to forecast inundation and current communication systems to avoid disasters remain problems described below.
-Water level prediction and large-scale flood prediction is being prepared and performed in the large rivers, but for the inner water and small rivers, it has not been implemented yet sufficiently.
-In order to minimize flood damages, it is necessary to assist in evacuation, such as by delivering the rapid inundation prediction information. However, currently there is no practical system that is available both for the inundation prediction and analysis in an integrated manner considering complex flow - flood phenomenon of urban areas.
In this study, a model that can predict urban flooding in real time and high precision was developed. In addition, the package system using the model to communicate information effectively was established, which is necessary for evacuation and flood prevention activities.
