| 摘 要： | 给出了平原水网地区水系局部改变后用于预测水情变化的水力边界条件的确定方法,以及因水系改变造成的水情、水质变化的计算方法,并将该方法应用于苏州市区水系水质变化分析。得出结论:水系变化必然产生局部水流形态的改变,最终影响污染物的对流扩散输运;局部水域水系改变愈大,模拟边界涵盖的范围应愈大。

| Abstract: | The method for determination of the hydraulic boundary condition is given for predicting the variation of water regime after the local variation of water system in plain river network regions, and the methods for calculation of the variations of water regime and water quality are also presented. The methods are applied to the water quality analysis for Suzhou City, and some conclusions are drawn: the variation of water system consequentially induces the local variation of flow patterns, and further affects the convection and diffusion of pollutants; the greater the variation of water system in the local water area, the wider the range covered by the simulated boundary. |
