受闸坝控制的河道水质预测方法研究

Water Quality Prediction for Channals Controlled by Sluices and Dams

根据扬洲古运河瓜洲闸的实际运行状况，恰当地选取连续４个月的时间作为预测期，在此基础上对古运河的水质进行预测，较好地反映了闸坝的不同运行方式对污染物在河道中稀释、扩散和运动的影响。实践表明：根据闸坝运行选取适当的预测期是做好水质预测与规划的基础。

On the basis of operation of Gaozhou sliuce on the Yangzhou canal,four months in succession is determinated as the prediction period.The predicted water quality within this period shows the effect on dilution,diffusion and movement of the pollutants in the canal under different operation conditions of the sliuce.The result obtained also shows that choosing the proper predition period according to the operation of the siluces and dams is the essential to the water quality prediction and planning of rivers.
