【摘要】 采用2-D浅水方程建立了嵌套模型。以乌江郭母子滩航道整治工程为例,模型研究了整治河段的水动力学特点以及对上、下游水流条件的影响。结果表明:该方法解决了整治河段近区难以直接获取边界条件的困难,能获得足够的计算精度,还能为工程提供全面的水动力信息,是预测和评估工程的有力工具。更多还原

【Abstract】 Based on the 2-D shallow water equations,a coupled model was established to study the hydrodynamic characteristic of the channel regulating river and the influence of the river upstream and downstream.An example was given which had been implemented in the channel regulating project of the GuoMuZi beach in WuJiang river.The case study demonstrated this model was a powerful tool of assessing the project,overcoming the difficulty of getting the boundary conditions in the near zone,and making the computation sufficient accuracy,and describing the flow field information in detail.更多还原
