提出预测水库水温和浊度的二维水质模型.利用日本下小鸟水库和下小鸟电站尾水渠道的实测数据确定模型参数,计算结果与实测数据吻合较好.应用控制模型对快速泄流、分层取水、栏栅以及栏栅和分层取水联合应用模式进行计算.结果表明,分层取水是减少浊流排放较为有效的方式.
A two-dimensional water quality model is proposed to predict the water temperature and turbidity of the reservoir.The model parameters are determined by the measured data of the Xiaoshiba Reservoir and the Xiaodiao Power Station tailrace channel.The calculated results are in good agreement with the measured data.Using the control model, , Stratified water withdrawal, fencing, combined application of fencing and stratified water withdrawal, and the results show that stratified water withdrawal is a more effective way to reduce turbidity discharge.
