为了模拟淮河中游洪水及污染物氨氮的变化过程,根据河道水动力特性以及污染物输送特征,利用2000-2003年6场洪水的流量、水质资料和451个断面的地形资料,建立了河网一维水动力模型和水质模型.经过模拟验证,模型计算的流量平均确定性系数为0.85,水质浓度变化与实测状况趋势保持一致,表明建立的模型具有较好的模拟效果,可为淮河水闸的防洪防污调度提供技术支持.
In order to simulate the process of the change of ammonia and nitrogen in flood and pollutant in the middle reaches of the Huaihe River, based on the hydrodynamic characteristics of the river and the characteristics of pollutant transport, using the flow of 6 floods, water quality data and topographic data of 451 sections from 2000 to 2003, Dimensional hydrodynamic model and water quality model.After simulation, the calculated average flow coefficient of the model is 0.85, the change of water quality concentration is consistent with the trend of the measured condition, which shows that the model has good simulation effect and can be used for flood control of Huaihe River floodgate Anti-fouling scheduling to provide technical support.
