Computation of contamination diffusion and transportation By Delft3D
Zhu Yu-xin
Abstract: It applies hydrodynamic Model to simulate COD of sewage around Xiaoyangkou, Rudong City, Jiangsu Province in this paper. Curvilinear orthogonal grid is used in interesting area, and hydrodynamics and water quality model are used to the current velocity field and tidal level field both on case of the spring and the neap tide. The computational results are compared with measured field data around drain. It shows that the simulation results are consistent with field data. In each case of spring and neap tide , velocity and direction play an important pole in transportation and diffusion , and the effect of sewage is maximum when ebb peaks in neap tide period.
Key words: curvilinear orthogonal grid ; COD ; diffusion and transportation ; water averaged
