摘要
建立了河口一、二维耦合水沙有限元模型,计算格式具有耗散小和精度高的优点。利用该模型计算了漳卫新河河口及河道水沙动力场,各站潮位、流速和含沙量过程计算与实测基本一致。经清淤、建闸和建导堤方案河道淤积量比较,推荐漳卫新河河口治理方案为导堤方案。
A FEM of one-two connection of current and sediment is established, the scheme has properties of high resolution and little dissipation, the procedure is much common use. Tide and sediment fields in the Estuary of Zhangwei xinhe is simulated, and the project of training dike is recommended.
