溃堤洪水的二维水动力模型及其应用
Two-dimensi onal hydrodynamic model and its application of levee-breach flood
摘要
Abstract
In order to reduce the significant loss of life and property caused by levee-breach flood and to improve the non-projec-tive measures in flood control and disaster prevention, a two-dimensional hydrodynamic model was developed to simulate levee-breachfloodaccurately.Dykebroadeningwastakenintoaccount,localmodelgridswererefined,andthemodelwasoptimizedu-singthehotstart,drywaterdepth,andwetwaterdepththeory.Inthispaper,themodelwasappliedtosimulatethelevee-breach flood routing in the southern irrigated area of Inner Mongolia section of the YellowRiver. T he actual dike burst data in Kuisu reachoftheYellowRiverwereusedtoverifythemodel.Theresultsshowedthattheflowfieldissmoothandwel-distributed, which indicated that the research results are reasonable and reliable. The model was also applied to simulate the working condi-tions that two dike burst occurred at Shagedu engineering and Kuisu reach respectively. Flood risk maps were plotted,which can provide important technical support for the flood control risk management and decision in the area.关键词
