崔家营航电枢纽下游水沙变化及其可视化研究

Study on downstream water and sediment variation of Cuijiaying Navigation and Hydropower Complex and its visualization

运用平面二维水沙数学模型,对汉江崔家营航电枢纽工程坝下游河床变形、冲淤平衡年限、同流量级下水流流态变化情况进行了预测。同时,充分利用Visal Basic语言和Fortran语言各自的优势,混合编程,实现了在二维地形基础上嵌套流场的动态可视化,直观地反映出流场与地形边界的关系。

Based on 2-D numerical water-sediment model, the riverbed deformation, desilting balance interval and the variation of flow pattern under the same flow rate of the downstream reach of the dam for Cuijiaying Navigation and Hydropower Complex on Hanjiang River are predicted. Meanwhile, the dynamic visualization of the inserted flow field on the basis of 2-D land form is realized by fully utilizing the advantages of both Visal Basic and Fortran, and then the relationship between the flow field and the boundary can be directly reflected as well.
