2-D Flood Routing Simulation on the Lower Yellow River from Huayuankou to Jianetan Based on Mike21 Software

Abstract:

The Lower Yellow River is apt to deposit and migrate. The reach from Huayuankou to Jiahetan is the typical wandering reach, which has broad and shallow body, intertwined tributary and numerous shoals. The mainstream always swings, and the riverbed deforms rapidly. There exist lots of residential places, irrigation canals, roads, productive dikes and other controlling works within the embankments, which greatly limits the scope of flooding. When the peak discharge is very large, the flood is prone to resulting in productive dikes bursting, which will greatly endanger the lives of residents in flood plains. The 2-D water flow mathematical model which reflects flood routing in the reach from Huayuankou to Jiahetan has been developed based on MIKE 21 software in this paper. Through the numerical simulation of the “96.8” typical flood, the simulating results in the condition of present topography are agreement with the measured ones. It shows that this model is basically reasonable in the selection aspects of river terrain, boundary treatment, roughness and water flow parameters, and the model has a reference value.
