Thermal Regime of Bovan Lake

<p>Bovan Lake is a reservoir in southeast Serbia, used mainly for water supply, flood protection and recreation. The purpose of this study is to better understand seasonal variations in water temperature by examining the thermal characteristics of the lake at various depths within the intake tower. Water and air temperatures were recorded at five different heights within the intake tower, with hourly measurements taken from December 2020 to November 2021. The results revealed that there were notable seasonal oscillations in the temperature of the water, with upper layers undergoing more fluctuations than deeper levels. A strong correlation among air temperature and surface water layers signifies a considerable external climatic impact, but deeper layers show enhanced thermal stability. This analysis contributes to a better understanding of the thermal dynamics of Bovan Lake and can serve as a basis for more efficient water resource management.</p>
