摘　　要：以山东省弥河流域为研究对象,依据流域河网、雨水情、数字高程模型(Digital Elevation Model,DEM)、土地利用、土壤类型等数据,基于分布式水文模型MIKE SHE耦合水动力模型MIKE 11建立分布式洪涝耦合模型,模拟河道洪水过程及河道外洪涝过程,选取谭家坊水文站实测洪水资料对模型进行参数率定,并结合现场调研数据对模型进行验证。结果表明,河道水动力模型可以较为准确地模拟河道洪水演进过程,分布式水文模型可以较好地模拟坡面洪涝演进过程,两者耦合形成的分布式洪涝耦合模型能结合两者的优点,较好地适用于弥河流域的洪涝模拟,模拟结果可为流域洪涝灾害风险评估、预报及预警提供数据支撑。Taking the Mihe River Basin in Shandong Province as the research object,based on data such as river network,rainfall and runoff situation,Digital Elevation Model(DEM),land use,soil type data,etc.,a distributed flood coupling model is established based on the MIKE SHE coupled hydrodynamic model MIKE 11.The model simulates the flooding process in the river and outside the river channel,selects the measured flood data from the Tanjiafang Hydrological Station to calibrate the parameters of the model,and verifies the model with on-site survey data.The results show that the riverine hydrodynamic model can accurately simulate the process of riverine flood evolution,and the distributed hydrological model can simulate the process of slope flood evolution well.The distributed flood coupling model formed by the coupling of the two models can combine the advantages of the two models and is suitable for flood simulation in the Mihe River Basin.The simulation results can provide comprehensive data support for the risk assessment,prediction,and early warning of flood disasters in the basin.
