【摘要】 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.更多还原

【Abstract】 A two-dimensional numerical model was developed for predicting the reservoir water temperature and turbidity.The model was verified with the measured data in the Shimokodori Reservoir in central Japan and in the tailrace channel of the Shimokodori Power Station in 2002.The predicted results were consistent with the measurements.The predictions were performed for different operational modes such as rapid discharging,selective withdrawal,fence,and fence plus selective withdrawal.The calculated results show that the selective withdrawal method is a good option.更多还原
