清澜港围滩工程前后潮流场的数值模拟

Numerical Computation of Tides and Tidal Currents Before and After the Engineering Project in the Qinglan Harbor

根据二维长波方程,用Leendertse分步全隐式格式方法建立差分方程,计算了清澜港附近海域的潮流场,在此基础上还考虑了在计算域内实施围滩造地和建造潜坝稳固沙咀工程后对计算域内流场的影响,得到了与实际观测值符合良好的结果.通过对多种工程方案前后流场及进出潮量的统计比较,为清澜港整治和合理开发提供了可靠依据.

An implicit difference equation of tides and tidal currents in the Qinglan Harbor, which takes into account the engineering project of enclosing beach and making underwater embankment to stabilize the beach cusp is obtained with results in good agreement with the observations. The comparison of the field of velocity and inflow & outflow in the mouth of the bay before and after the engineering project can provide reliable basis for the engineering of enclosing beach.
