  • AQUATOX

    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.

  • What's New in AQUATOX Release 3.2?

    AQUATOX Release 3.1 includes numerous significant enhancements over previous versions that increase the realism and utility of the model. The most important enhancements include:

  • AQUATOX Basic Information

    AQUATOX is an ecosystem simulation model that predicts the fate of various pollutants, such as excess nutrients and organic chemicals, and their effects on aquatic ecosystems, including fish, invertebrates, and aquatic plants.

  • Potential Applications for AQUATOX

    AQUATOX has a myriad of potential applications to water management issues and programs, including water quality criteria and standards, TMDLs (Total Maximum Daily Loads), and ecological risk assessments of aquatic systems.

  • What does AQUATOX do?

    AQUATOX simulates the transfer of biomass, energy and chemicals from one compartment of the ecosystem to another.

  • AQUATOX Features and Tools

    Numerous features have been included to facilitate the modeling process, from model setup and data input, presentation and analysis of results, to easy export of results to spreadsheet programs for additional analysis.

  • AQUATOX Training Workshops
