Abstract

Thermal stratification in prevents reservoirs oxygen to reach the bottom layers. In this study, the effects of upstream reservoirs in thermal stratification of downstream reservoirs have been investigated. This paper presents the results in two different conditions; single and tandem reservoirs.
 
In single reservoir conditions, inflow to each reservoir is the natural river stream. In tandem reservoirs condition, the effect of each reservoir on downstream reservoirs is examined. Comparing the results of these two conditions explained the induced thermal stratification phenomena. This study is performed using HEC-5Q software.
