浸水危険度簡易評価法の研究

抄録

Recently, Inundation damages occur caused by heavy rainfall. Thus, the demand for evaluation of inundation risk rises. It is revealed that it is difficult to simply evaluate with the same standards risk of inundation for sites that extended over local governments. In this study, a simple evaluation method for inundation risk using the Nationwide altitude, the Laplacian calculated from the altitude, the Terrain classification and a logistic regression is investigated. The evaluation is compared actual inundation areas. As the result, it is revealed that the method is effective for simple evaluate with the same standards risk of inundation.
