| 摘 要： | 针对河口海岸数值模拟的动边界问题,使用了一个简便的干湿网格法,对BOM(Burgen Ocean Model)模型进行了动边界改进。并将该模型应用于瓯江口海域进行数值模拟计算,计算结果表明实测值与计算值吻合良好,模型能够较好的模拟岸边界随潮位涨落的变动。

| Abstract: | A wetting and drying scheme is proposed and imbedded in BOM in this paper to deal with the problem of moveable boundary in coastal and estuarine simulations.Using the improved BOM, a channel with a step, a dump and a bowl-shaped bottom and the Oujiang River estuary are computed.The tests show that the model is effective.The comparison of the measured values and computed values of water level and velocity is acceptable. |
