摘　　要：以沙颍河槐店闸为研究对象,构建了闸坝调控作用下二维水动力-污染物迁移模型,根据试验获取的数据对模型进行率定和检验。结果表明:闸坝的存在对河流水环境系统具有一定负面影响,但是合理的闸坝调控能够改善河流水质,减小突发性水污染事故发生的概率;该模型可以有效地模拟计算闸坝调控作用下污染物的迁移过程。Taking the Huaidian Gate of Shaying River（in the Huaihe River watershed） as a research object,two-dimensional hydrodynamic for contaminant transport was proposed in this paper.The model was calibrated and tested comprehensively using the experimental data of Huaidian Gate.The results show that gate dam on the river have a negative impact on river water environment system.However,reasonable gate dam operation can improve water quality and mitigate the probability of water pollution accidents.This model can effectively simulate contaminant transport in the river influenced by gate dam operation.
