A real-time mathematical model for three-dimensional tidal flow and water quality is presented in this paper. A control-volume-based difference method and a “power interpolation distribution” advocated by Patankar (1984) have been employed, and a concept of “separating the top-layer water” has been developed to solve the movable boundary problem. The model is unconditionally stable and convergent. Practical application of the model is illustrated by an example for the Pearl River Estuary.

Wenzhou Shoal

By means of natural condition and mathematical models of tidal flow and sediment, numerical study is carried out on suspension-diffusion in construction period after the reclamation project of Wenzhou shoal at Oujiang estuary in this paper. The main conclusions are: the suspension-diffusion is controlled by tidal current. The range of suspended sediment concentration more than 10mg/L is mostly in Wenzhou shoal area during filling sand construction, which is the continuous operation. Riprap construction is Instantaneous work; the range of scatter is limited.

By the2-D tidal flow mathematical model, Calculation and analysis of hydraulics r Characteristics of the Longkou ine LV four port rcclamaiton project;and the relationship between the fill area and the width of of longkou. Research shows that, after the completion of an embankment, with the inning area fill, Longkou velocity gradually decreases. In I, II area harbor dam is formed, When the fill range from Longkou 1km ,and the Long kou width is reduced to 50m, I, II zone Longkou maximum velocity were 1.42m /s、1.54m / s, can meet the requirements of the closure gap.when III area harbor dam formed,if the fill maximum range from Longkou 1km, then closure-gap width at least to maintain 200m; for closure-gap width below 100m, then in the north and south area at the same time need to built bank. The ebb tide duration of the Longkou greater than the flood tidal duration;during the ebb tide, flow velocity basically stable, relatively small, Longkou closure should be selected during low tide and the low tide period.
