What is meant by "water turnover" in reservoirs?

Water turnover in reservoirs refers to the rate at which water is replaced or renewed. This concept is crucial because it impacts the overall health of the aquatic ecosystem within the reservoir. Higher turnover rates can lead to better water quality, as they allow for the dilution of contaminants and enable the replenishment of oxygen and nutrients. Additionally, understanding water turnover can help in managing water supplies, as it dictates how quickly water can be cycled through treatment processes or available for distribution.

The measurement of turnover is an important aspect of managing reservoirs, as it directly affects not only the physical and chemical properties of the water but also biological processes within the environment.
