Numerical computation of two-dimensional tidal current and sediment for Changan port
Changan port is located in the north of Jiaoyi bay in Lingdingyang. The reclamation project and port basin project will be carried out in Changan port. In the paper, the effects of the planning scheme of Changan port on the sediment siltation of the adjacent water areas are analyzed by field data analysis, suspended sediment remote sensing analysis and tidal-sediment model simulation. After analysis, some conclusions can be obtained as follow. (l)The two planning schemes have the similar effects on the adjacent water areas. Both of the two planning schemes have little effects on Dachanwan port area. The velocity of flood tidal of the west waterway in Lingdingyang, especially in the north waterway of the engineering areas decreases, while the low direction changes slightly. The velocity of one-stage port basin in Nansha port area decreases in somewhat degree. In all, the construction of the two planning schemes has little effects on the adjacent water areas. (2)There are little effects on the sediments transport by the two planning schemes. The sediment siltation increase slightly in the west waterway in Lingdingyang and Nansha port while has little differences in Dachanwan. (3)In all, the first planning scheme would lead better hydrodynamic conditions in Dongtan than the second planning scheme, while the latter has more advantage in maintaining the hydrodynamic conditions of the west waterway in Lingdingyang. Generally, there are little differences between the sediments transport by the two planning schemes.
