Abstract

Reservoirs serve a lot in solving water shortage problems. It is critical to ensure the quality in the reservoir. Turnover time is identified to influence the water quality significantly. In this study, the effect of air temperature variations on turnover time in a reservoir on Fushan Mountain (Qingdao, Shandong Province, China) has been investigated by field observations. We have monitored the temperature profiles in the reservoir during the stratification period and mixing period in continuous three years. The theoretical turnover time was also calculated. The monitored data indicated that the turnover time in 2016 was much earlier than that in other two years. The reasons for turnover time variations were studied. Ruled out the possible effects of wind, water depth and the average hypolimnion temperature, the air temperature fluctuation (affecting the epilimnion water temperature mostly) was found to be in charge of the reservoir being mixed earlier. Therefore attentions should also be focused on air temperature fluctuation in the prediction and management of seasonal stratified reservoirs.
