摘要
文章通过水热平衡方程,以辽宁大伙房水库为研究实例,对该水库下泄水温进行模拟。研究成果表明:水热平衡方程可较好的模拟水库下泄水温。通过对大伙房水库运行前后水温进行模拟,水库运行前温变率变化较为规律,水库运行后,水温温变率波动特征明显,尤其是在7月下旬—9月中旬,下泄水温的温变率较水库运行前有较为明显的变化。
In this paper,the water and heat balance equation is used to simulate the discharge temperature of Dahuofang reservoir in Liaoning Province.The study results show that:the water-heat balance equation can well simulate the water temperature of reservoir discharge.The water temperature before and after operation of Dahuofang reservoir is simulated,the fluctuation of water temperature and temperature after reservoir operation is obvious,especially from late July to mid-September,and the temperature variation of discharge water temperature is more obvious than that before reservoir operation.
