洪水灾害危险性评价方法的研究与改进
Research and improvement on assessment method of flood hazard
摘要
Abstract
Flood risk analysis is an important part of non-engineering flood control measures,and flood hazard assessment is the basis of risk analysis.Due to the need to obtain submerged water depth,the existing assessment methods of flood hazard re-quires complex hydraulic models and high-resolution data,but during operation,it is often impossible to meet the data require-ments.In order to simplify the process of flood hazard assessment and ensure the accuracy of the results,this paper presents a new simple and integrated flood hazard index.The index is based on Gisnet and ArcGIS and combines with the distributed hydrological model.In light of the formation mechanism of flood hazard,the index comprehensively considers the natural attrib-ute of distributed streamflow and topographic index.Based on the specific situation of the Hongluogu in Beijing mountain area, we tested the new index.The results showed that FHI can truly reflect the trend of regional flood with spatial change.It can provide a new idea for the future flood hazard assessment,and has great significance to the improvement of flood risk study sys-tem.关键词
