GLM: The General Lake Model

The General Lake Model (GLM) is a water balance and one-dimensional vertical stratification hydrodynamic model. It accounts for the effect of inflows/outflows, mixing and surface heating and cooling, including the effect of ice cover. It is suited to longer-term investigations ranging from seasons to decades, and for coupling with biogeochemical models to explore the role that stratification and vertical mixing has on biogeochemical and ecological dynamics of lakes, reservoirs, ponds and wetlands.
