基于淹没模型的洮河流域暴雨洪涝风险区划
Tao River Rainstorm Flood Risk Regionalization Method Based on Flood Inundation Model
摘要
Abstract
Using submerged model of ArcGis calculated the relationship between Tao River basin precipitation and Liujiaxia Reservoir water level changes,confirmed the surface precipitation of the Tao River basin and hydrology water level curve.Gumbel extreme value type I distribution method was used to calculate different return period of surface precipitation in the basin. D8 and Manning Formula was used to calculate river basin within the scope of different return period surface precipitation of the submerged area and depth. Using the principle of disaster risk,made Tao River basin rainstorm flood risk regionalization,compared with the distribution and heavy rain days in the basin,the results showed that the corresponding was better between Tao River basin rainstorm floods in high risk area and heavy rains flood occurred frequently area,had a clear physical meaning.关键词
