复杂边界河流水质预测计算

RIVER WATER QUALITY PREDICTION AND CALCULATION OF COMPLICATED BOUNDARY

山东省济宁市境内的洙赵新河汇入南四湖的南阳湖区,水流受南阳湖顶托影响,河道上建有多处节制闸来调控水量。在洙赵新河入河排污口设置论证工作中,需要对河道水质变化进行预测分析。本文中在对洙赵新河的复杂水流、水质条件详细调查分析基础上,选择合适的水质预测模式,并对河道水流、水质边界条件进行合理数值概化,建立洙赵新河一维水质数值模拟模型,成功应用于该河流的水质预测任务。

The Zhuzhao New River in Jining Shandong province flows into the Nanyang Lake of Nansi Lake, whose water holds by Nanyang Lake, and multiple floodgates built on the river to control discharge. In the study of Contaminant Outlet Setuping on the river, water quality prediction is demanded. In this paper, based on par- titular inquiry and analysis about the complicated flow and quality of Zhuzhao New River, the author selects on adaptive water quality model, numerically disperses appropriate water flow and quality boundary eonditions, and builds a one - dimension water quality simulation model which is successfully applied to predict the water quality change of the ZhuZhao New River.
