摘要
为验证模型参数取值的合理性,以河南省沱河片防洪保护区暴雨内涝为研究对象,采用Mike系列软件构建一、二维耦合模型,根据2018年18号台风实测暴雨过程,模拟降雨情况下区域内的涝水演进过程及分布情况,将得到的模拟成果与现场调查的洪涝灾害情况进行对比,验证二维暴雨内涝模型参数选择方法和取值,并为其他防洪保护区洪水模型参数选取提供依据.
Abstract
In order to verify the rationality of the model parameters,taking the storm waterlogging in Tuohe River flood protection area in Henan as the research object,1D&2D coupling models are constructed with Mike series software for simulation of waterlogging evolution process and distribution based on the observed storm process of Typhoon No.18 in 2018.The simulation results and the actual flood waterlogging disasters are compared to verify the parameters selection method and the value of the 2D storm waterlogging model,which provides the basis for flood model parameters selection of other flood protection area.
