Numerical study of hydrodynamic characteristic and pollutant transport in Zhuanghe aquaculture waters

摘要：

　　A depth-averaged 2d hydrodynamic model was developed to solve 2d shallow water equations based on the finite volume method.The implicit scheme was applied to present the large time step in this model.The computational mesh adopted multi-level quadtree rectangular cells.The governing equations were solved using the SIMPLEC algorithm on non-staggered grid to handle the coupling of water level and velocity.The pollutant transport model consisted of a Lagrangian method for the advection process and the random walk technique for horizontal diffusion process.The coupling model was tested against measurement data reported from analytical resolution, tidal flows and the trajectories of particles for real waters,an agreement between the simulated results and experimental data could be found, the model displays a sufficiently efficiency and accuracy in solving the question for flow and pollutant transport with a large time step in sea waters.
