Code for the General Lake Model

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.

Accessing the model

This GLM repository is released coupled with the AED water quality model, via the GLM-AED release. Refer to the glm-aed repository for pre-compiled model executable files, example simulations, and information for how to get started with the model.
