Tidal Flow Numerical Simulation Study on the Reclamation Project of Beiao Houtu of Dongtou Island

A 2-D tidal flow mathematical model near Dongtou Island based on irregular triangular grid finite difference scheme is set up. On the basis of model verification against filed measured data, numerical simulations of tidal flow field before and after the reclamation project of Beiao Houtu are carried out. According to the simulation results, the effect of the reclamation project on the nearby sea area and the scouring at the foot of the reclamation wall are studied and analyzed. The study and analysis results show that the reclamation project will not cause obvious effect on the passenger wharf,freight terminal and navigational channel, causing little effect on the tidal flow, on the piers of Sanpan Bridge and on its apertures for navigation of ships, and there being little possibility for the foot of the reclamation wall to be scoured by pure tidal current. The reclamation project is feasible.
