The General Lake Model is a one dimensional water balance and vertical stratification model, which is suited to the environmental modelling studies where simulation of lakes or reservoirs is required. It computes vertical profiles of temperature, salinity and density by accounting for the effect of inflows/outflows, mixing and surface heating and cooling, including the effect of ice cover on heating and mixing of the lake. GLM incorporates a flexible moving layer structure. It allows for layers

When sufficient energy becomes available to overcome density gradients, two layers will merge thus accounting for the process of mixing. Unlike the fixed grid design where mixing algorithms are typically based on vertical velocities, numerical diffusion is limited, making the GLM approach also suited to long-term investigations. The model has been developed as an initiative of the Global Lake Ecological Observatory Network (GLEON) and in collaboration with the Aquatic Ecosystem Modelling Network (AEMON) that started in 20107. GLM can be coupled with biogeochemical models through a specific interface (Framework for Aquatic Biogeochemical Models, FABM). FABM supports coupling of a diverse array of water quality and ecological models to various physical driver models, ranging from a zero dimensional box model to a suite of 1, 2 or 3-dimensional hydrodynamic models. FABM includes various ecological models, including numerous Aquatic Ecodynamics (AED) component modules suited to lake ecological modelling. Currently these include modules for simulating the dynamics of oxygen, carbon, nutrients, organic matter, phytoplankton, zooplankton and sediment.
