Modeling the Hydraulic Condition of the YRD Wetlands Using A 1D-2D Integrated Hydraulic Model

摘要：

It is a key to a 1D-2D integrated hydraulic model of Yellow River Delta (YRD) that correctly modeling the hydraulic condition. Based on hydrology and hydraulics, and according to the wetted parts of cross sections, discharge of the river, the skeleton of model was built firstly, then we schematized the lateral flow, ground water seepage, precipitation, evaporation, etc., and ran and verified it. After modifying the value of coefficient, calibrating the water level process several times in simulation period, the result shows that the final model has a good agreement. So the overland model in YRD was built on the channel model and simulated the flow in wetlands after pumping from YR. Then the channel model and overland model make up the YRD wetlands 1D- 2D integrated hydraulic model.
