Abstract

The use of water reservoirs causes imbalance in water temperature in rivers. Furthermore water reservoirs are always in danger of contamination by different types of pollution such as TDS especially during floods. This paper presents the effect of water withdrawal from two different levels on the quality of the output water in terms of pollution. Furthermore the best amount of discharge is selected for each level in order to minimize the amount of TDS (exiting the reservoir) and Temperature difference between inlet and outlet water. Results indicated that the use of two different output levels in terms of pollution Improves the objective function value compared to the use of a single output level. For example the application of two different output levels in spring can reduce the amount of pollution as much as 11.81%. In addition difference between inlet and outlet temperature was seen to decrease as much as 4.02%.
