A large focus of the Aquatic EcoDynamics group is in the development of new, open-source models in partnership with a global network of collaborators to provide the reserach and management community with a high-quality and easy-to-use modelling toolkit. The main software we develop is the Aquatic Ecodynamic (AED) model library that includes extensive water quality and aquatic ecology modules suited to a wide variety of applications.
AED (& FABM-AED): Aquatic Ecodynamics Library
Within our group we develop the AED modules that are able to model turbidity, nutrients, algal blooms, pathogens, acid sulfate soils and general ecosystem interactions.
They can be used as a stand-alone library of water quality and aquatic ecology functions, or they can be invoked through FABM (Framework for Aquatic Biogeochemical Models). The philosophy of the AED modules is that individual model components can be configured in a way that facilitates custom aquatic ecosystem configurations. Users select modules they wish to simulate and then are able to customize connections with other modules. In general, model components consider the cycling of carbon, nitrogen and phosphorus, and other relevant components such as oxygen, and are able to simulate organisms including different functional groups of phytoplankton and zooplankton, and also organic matter.
We use AED coupled to the 0D FABM box model driver, the 1D lake model GLM, the open-source 3D model GETM, and we are also working with BMTWBM and have linked AED with the 2D / 3D finite volume model TUFLOW-FV.
The AED library is designed to simulate:
GLM: Lake Hydrodynamics
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
GLM is suited for use in:
WET0D (and the R-implementation WET-R) is a simple 3-compartment wetland ecohydrological model for studying the interaction of wetland vegetation functional groups with the water balance of wetland systems. The model was developed by Janaine Coletti as part of her PhD and has appliction in semi-arid wetlands including those impacted by salinisation. The model additionally includes a carbon cyling component.
SMILEis a simple box model for nutrient accounting in lakes and estuaries. The model was developed by Ana Laura Ruibal as part of her PhD to unravel dynamices of systems from long-term monitoring data.
