多闸坝河流水质模拟

Water Quality Simulation of Multi-Sluices

以清潩河为例,分析了其开发利用情况和闸坝使用情况,以COD为研究对象,对清潩河流域污染源、河底高程等进行概化。基于EFDC分段建立清潩河的一维模型,进行水动力水质模拟。通过与河流监测断面水质实测值对比进行模型校准,上段的107国道桥断面平均相对误差为12.8%,下段的陶城闸断面平均相对误差为4.5%,模拟结果与实际数据相比误差较小,模型较为准确。

In this paper,Qingyi River as an example,analysis of its development and utilization of the situation and the use of sluices.Taking COD as the research object,generalize the pollution source and river bottom elevation of Qingyi River Basin.Based on EFDC segmentation,a one-dimensional model of Qingyi River is established to simulate hydrodynamic water quality.The relative error of the section of the new section of the G107 section is 12.8%,respectively,compared with the measured value of the river monitoring section.The average relative error of the Taochengzha section is 4.5%,respectively.The simulation results are less accurate than the actual data,and the model is more accurate.
