Stratification in a lake

WebDestratification is the process of disrupting thermal layers and/or chemical layers in a body of water, particularly in lakes and reservoirs. Destratification is often associated with the mixing process because both have the same purpose to homogenise the water column for improving water quality. WebFor example, in a stratified lake, nutrient concentrations may be high in the bottom waters but low enough in the surface water to limit phytoplankton growth. Consequently, it is critical to understand the drivers of lake mixing and thermal stratification, especially because of the sensitivity of lake thermal conditions to altered climate.
