| 摘 要： | 基于河流一维水质模型基本理论，采用流场与水质耦合求解法，对钱塘江九溪新增引水工程在不同引水方案和水组合下，对钱塘江下游各水厂取水口含氯度的影响进行了数值计算和分析．分析结果表明，九溪新增引水工程使下游水厂引水口含氯度超标时数增加不多于100h，在可承受范围之内．

| Abstract: | Based on the elementary theory of river water-quality simulation, an 1-dimensional numerical model and the coupling resolving method have been taken to calculate and forecast the changes of chlorinity near water intakes in the downstream reach of the Qiantang River caused by Jiuxi new diversion work under the condition of different combinations with different diversion discharge, different hydrological conditions. The result shows that the new diversion work will increase less than 100 hours of the (period) of the chlorinity exceeding the assessment criteria, which is acceptable. |
