在过去几十年,人们对城市洪水风险研究的兴趣越来越浓厚。以荷兰普林森贝克流域为例,采用来自当地雨量站、投诉登记表和模型计算的数据,对城市洪水频率评估中不确定因素的影响进行了分析,并将理论模型的结果与实际情况进行了对比。结果表明,城市洪水排泄系统缺乏维护是造成城市洪水的重要潜在原因。 In the past few decades, people have become more interested in the research of urban flood risk. Taking the example of the Prinsberg Beck Basin in the Netherlands, this paper analyzes the influence of uncertain factors in the urban flood frequency assessment by using data from local rainfall stations, complaint registration forms and model calculations. The results of the theoretical model and the actual situation are analyzed Contrast. The results show that the lack of maintenance of urban flood drainage system is an important potential cause of urban flooding.
