摘要
数学模型是防洪评价的一个重要技术手段。介绍了广州水道某码头工程局部水域平面二维水沙数学模型的建立和验证及实际应用效果,结果表明,模型能较好地模拟工程附近水流泥沙运动以及河床冲淤变化规律,为预测分析工程建设对河道河床冲淤演变影响以及量化分析提供了一种手段和途径。
Numerical model is an important technical means for preventing flood evalutiaon.In this paper,2-D numerical model of tidal current and sediment for a wharf project on Guangzhou channel is established under the boundary-fitted curve coordinate sysytem based on flow equation and equilibrium transport equation of suspension,the validity of the model is verified by the hydrographic data.The application affords new ways and means for preventing flood evaluation.
