摘要
针对钱塘江河口区的水流特性和水质特点,建立对钱塘江河口上段富春江电站至杭州闸口区间的二维动态水流水质模型,选取2004年全年水位和水质资料进行率定,结果基本一致。初步进行了河段全年长历时水质计算分析,提出污染物负荷总量控制削减方案,为下一步污染物负荷排放优化决策,预测钱塘江水质趋势提供了模型基础。
A two dimensional dynamic water flow and water quality model was established for the Qiantang estuary, focusing on the upstream reach between Fuchunjiang waterpower station and Zhakou. Model calibration was conducted using the measured data of the full year 2004, water level data and water quality data at Tonglu, Zaixi, Fuyang and Wenjiayan Stations. The calculations showed an agreement with the measured data. Through preliminary calculations and analysis of water quality for this reach over the full year 2004 with different probability of hydrology, a scheme of pollution load cutting of the Qiantang Estuary was proposed, which is fundamental to restore water environment of Qiantang estuary.
