Abstract
Theflooddevelopmentinthefloodstorageareahastheobvioustwo-dimensionalcharacteristics.Thenecessityofthesimulationof storage and detention zones, two dimensional flood evolution model fundamentals and numerical solution, example analysis and model validation are discussed in this paper. Using two-dimensional hydrodynamic method, the flood storage and detention area simulation model is established. Combining withdisplayfinitedifferencemethodandtheadvantagesoffinitevolumemethod,themodelcansimulatetheinfluenceof riverbank, brake,channel,pump,andsurfaceimperviousarea.Channelinthismodelisdividedintodifferenttypesanddifferenttypesofchannelcalculation blockhaveacorrespondingprogramcode.Dividedmeshadapttotheterrainmuchbetter.ForJiakouwafloodstoragearea,ithascarriedoutflood inundation situationsimulation.Themodelcansimulatethefloodsubmergeddepth,thefloodflowvelocity,themaximumdepth,thefloodstriker arrival time,etc.Based on the 1954 historical flood simulation, it verifies the feasibility of the model.The results provide technical support for floodcontrolanddisasteralleviationandemergencymanagementintheflooddevelopmentoffloodstoragearea.Atthesametime,it canprovide reference for flood risk analysis and evaluation in the related fields.关键词
