摘　　要：采用三维浅海潮波定解方程组,建立番禺附近海域的三维潮流数值模型来计算潮流和潮位变化情况,开边界采用调和常数计算的水位来驱动,潮流和潮位验证结果较好,模拟结果较真实的反应了番禺附近海域的潮流和潮位情况。在潮流模拟验证正确的前提下,建立溢油预测数值模型,采用欧拉-拉格朗日追踪方法,对油膜中心轨迹进行预测,并预测出油膜的平均速度、漂移距离、消失时间、残留量、扫海面积以及去向等。By means of three-dimensional shallow tidal wave equation group,a three-dimensional tidal simulation model is established to compute the current and tide changes of the sea area near Panyu.The open boundary is driven by the level computed by harmonic constant.The verification results of tide and tidal current are quite good.The simulated result realistically reflects the tide and tidal conditions in the area near Panyu.In the context of well verified tide simulation result,oil spill forecast numerical model is established,using Euler-Lagrangian tracking method to predict the trajectory of the oil film center,and will forecast the diffusion area,sweep area,and residues with time of oil film.
