钱塘江(新安江大坝-富春江大坝)水质模拟

Water Quality Simulation of Qiantang River between Xinanjiang and Fuchunjiang Dam

针对钱塘江上游段的水流特性和水质特点,建立了钱塘江(新安江大坝-富春江大坝段)一维河网水动力、水质模型,选取2010年9月7-10日实测流量、水质数据对模型进行了验证,结果基本一致。利用该模型预测了不同方案条件下主要取水口及水环境功能区边界的水质变化,分析了影响水质的主要因素,为水环境质量改善提供了决策依据。

According to water flow and water quality characteristic of the upper reaches of Qiantang river, an hydrodynamic and water quality model with one dimensional river network was established between Xinanjiang and Fuchunjiang dam. The model was calibrated by actual water flow and water quality data measured from September 7 to 10, 2010. The calculation nearly accorded with the measured data. The model predicted water quality variation of main water intake and boundary of water environment functional region in different schemes, analysed main factors which influenced water quality, and helped the decision making to water environment quality improvement.
