摘要
Abstract
The four major astronomical tides and their corresponding Lagrangian tide-induced circulations are simulated numerically in the Yellow Sea and the shelf area of the East China Sea. By applying the SCM (Splitting Current Method) to the model the linear 3D tidal constituents equations are transformed into a tidal elevation equation, a 2D depth averaged current equation and the solution of a vertical current profile. The bottom friction coefficient in the 2D case is deduced from the 3D model. It reflects a clear physical understanding and avoids the empirical assumption made in the normal 2D model for the bottom friction. It shows that in this paper the 3D numerical model can be solved by a quasi-2D model and thus skip the tremendous computation in the normal 3D model.关键词
