Abstract

Reservoirs are among the most important sources of water supply that can affect the quality of water by changing the temperature. Conditions affected by climate change could affect the thermal regime of reservoirs water. This study investigates the temperature variation of water in Aidoghmoush reservoir depths under climatic conditions in the 10-year period of climate change (2030-2039). Temperature and precipitation are extracted by the CGCM2 model (IPCC’s Third Assessment Report) under a B2 emission scenario in the 10-year period of time (1991-2000) and then they were estimated for future conditions. In the following, thermal stratification simulation is performed by the CE-QUAL-W2 qualitative model. The results show that the temperature at the water surface and the floor of the reservoir will increase in conditions of climate change relative to the baseline conditions. The water temperature will increase by an average of 1.5 oC. The findings of this study will help managers and planners to optimize water resources management.
