摘　　要：采用海岸工程水动力学数学模型对黄茅海潮流场及波浪场进行了计算.潮流计算中利用水平方向上的曲线正交坐标与垂直方向上的Sigma坐标相结合以及三维模型二维化的方法,波浪计算采用双曲型缓坡方程,并引入改进型的非线性弥散关系,从而能反映波浪的非线性效应.计算结果与实测结果比较表明:模型能较好地复演黄茅海潮流及波浪场,可以用于工程实际中沿岸及河口湾潮流波浪场问题的计算.The hydrodynamic numerical model for coastal projects was used for calculation of tidal current and wave fields of Huangmao Sea. In tidal current calculation, the c urvilinear orthogonal coordinates in horizontal direction was combined with Sigma mapping coordinates in vertical direction, and a hyperbolic mild slope equation with the introduction of an improved nonlinear dispersion was adopted for wave calculation, so that the nonlinear effect of waves could be reflected. The calculated results are in good agreement with the measured data. Therefore, the model can be applied to coastal and estuarial prelects.
