AQUATOX - Linking water quality and aquatic life

AQUATOX models the fate of various pollutants and how they affect aquatic life.

AQUATOX is a simulation model for aquatic systems. AQUATOX predicts the fate of various pollutants, such as nutrients and organic chemicals, and their effects on the ecosystem, including fish, invertebrates, and aquatic plants. This model is a valuable tool for ecologists, biologists, water quality modelers, and anyone involved in performing ecological risk assessments for aquatic ecosystems. Although incorporating constructs from classic ecosystem and chemodynamic models, AQUATOX was developed from the beginning as an applied model for use by environmental analysts.

Release 3.1 of AQUATOX is now available. Release 3.1 contains several enhancements over previous releases that improve the model's interface and utility.  For example, the sediment diagenesis model has a "steady-state" mode that increases model speed dramatically.  Other categories of refinements include floating-plants refinements, bioaccumulation and toxicity modeling improvements, and improved sensitivity and uncertainty analyses.

AQUATOX Release 2 underwent an external peer review in late 2003. Release 3 underwent external peer review in late 2008.
