Abstract
Using the Delft3D two-dimensional mathematical model to simulate the water flow in the Poyang Lake inflow channel,combined with the construction plans of three docks in the port area,a reasonable rectangular grid division was car-ried out.The measured water level data from the upstream five rivers and the downstream Hukou station were used for cali-bration and verification to determine the roughness coefficient and eddy viscosity coefficient of the simulated river section.Two boundary conditions were selected to calculate the changes in water level and flow velocity before and after dock con-struction.After data processing,an contour map of the difference in water level and flow velocity before and after engineering construction was formed.The maximum height of the three docks in the port area was 0.95 cm,and the maximum increase in flow velocity was 0.17 m/s.The engineering construction had little impact on the backwater and flow velocity of the Poyang Lake inflow channel.Therefore,Delft3D can quantitatively analyze the impact of newly constructed docks on the blocking and flood discharge capacity of the Poyang Lake inflow channel,providing strong technical support for obtaining reasonable flood control evaluation conclusions.关键词
