摘要
以深圳市梧桐山河流域为研究区域,基于HEC-RAS模型建立梧桐山河流域一维水动力水质模型。水动力模型最大相对误差2.43%,水质模型最大相对误差18.12%,模型模拟精度较高。利用该模型对河段水体中的污染物进行模拟,根据上游污染物浓度估算污染物扩散至下游断面的浓度及扩散时间,模拟调控上游水库的下泄流量来加大生态流量,从而达到控制污染物浓度的目的。
Taking the Wutongshan River basin in Shenzhen as the study area, a one-dimensional hydrodynamic water quality model of the Wutongshan River basin was established based on the HEC-RAS model. The maximum relative error of the hydrodynamic model is 2.43%, and the maximum relative error of the water quality model is 18.12%, of which the simulation results are good and reliable. Then the model was used to simulate the pollutants in the river. The concentration and diffusion time of pollutants to the downstream section were estimated according to the upstream pollutant concentration, which could regulate the discharge of the upstream reservoir to increase the ecological flow, so as to control the concentration of pollutants.
