摘要
应用河口、陆架和海洋模式 (ECOM模型 ) ,引入干湿网格法模拟潮滩涨落的改进 ,并建立丁字湾及近岸海域的三维变动边界潮流模型。该模型考虑了湾口拦门沙、湾内水道和人工围海等地形特点。计算结果与实测值比较符合良好 ,较好地刻画出丁字湾 M2 分潮潮流场的时空分布特点。
A 3-D numerical tidal model to simulate M 2 tidal cu rrent field with a mobile boundary in Dingzi Bay is established in this paper. T he model is based on an international 3-D coastal ocean circulation model (ECOM model), and is modified for incorporating dry-wet grid technology to simulate flooding and ebbing in tideland. Some complex topography is taken into account, including some fords in the bay mouth and the waterway and the artificially encl osed tideland. The computed results match well with the observed ones, which imp lies that the model is capable of describing the temporal and spatial distributi on of M 2 tidal current in Dingzi Bay.
