提出了水深与流场缓变水域波浪传播数学模型———水流中依赖时间变量并考虑能耗的波浪“缓坡方程”及其等价的控制方程组，分析比较了无水流情况此理论模型与其相应的两种抛物型近似的差别，提供了长江口波浪变形数值模拟计算工程实例．实例表明，该模型能适应河口三角洲大范围水域波浪传播数值计算．
The mathematical model of wave propagation in water area with slowly changing flow field is put forward. The “gentle slope equation” and its equivalent control equations depend on the time variable and the energy consumption in water flow. The theoretical model of water flow is analyzed and compared with The corresponding differences between the two parabolic approximations provide examples of numerical simulation of wave deformation in the Yangtze Estuary. The example shows that the model can adapt to the numerical calculation of wave propagation in a wide range of estuarine delta.
