The AED2 modelling library is an open-source community-driven library of model components for simulation of "aquatic ecodynamics" - water quality, habitat and aquatic ecosystem dynamics. Users select water quality and ecosystem variables they wish to simulate and then are able to customize connections and dependencies with other modules.
AED2 is suitable for a wide range water bodies, including lakes, reservoirs, wetlands, estuaries and coastal waters. It has been applied to many research and engineering projects across world.
SCEVO is a not-for-profit initiative to disseminate information about the Swan-Canning Estuary system, and provide online simulations for the benefit of researchers and the Perth community using AED2 coupled with other hydrodynamic and climate models.
One of the challenges with complex ecological models is reducing error and quantifying uncertainty. As part of an ARC Discovery Project we are working with Prof Justin Brookes from the University of Adelaide to simulate the Lower Murray River and Lake Alexandrina using novel data-streams to undertake an advanced process validation of the model.
As part of an ARC-Linkage project "Balancing estuarine and societal health in a changing environment", AED2 is coupled with 3D hydrodynamic model TUFLOW-FV with aims to produce a predictive decision support tool for helping identify land-planning solutions in response to fast growing population and changing climate.
The AED model is used with TUFLOW-FV to unraveling the complex sources, delivery pathways and cycling of nitrogen along a sub-tropical freshwater-marine continuum. This study is significant because the combination of these 3 approaches will for the first time provide an unprecedented understanding of the complex processes involved in nitrogen cycling along a whole freshwater-marine continuum.
