Exposure Research: Land and Waste Management

Methods, Models, Tools and Databases

Tools

  • Supercomputer for Model Uncertainty and Sensitivity Evaluation (SuperMUSE)

    EPA’s Supercomputer for Model Uncertainty and Sensitivity Evaluation, or SuperMUSE, enhances quality assurance in environmental models and applications. Uncertainty analysis (UA) and sensitivity analysis (SA) remain critical, though often overlooked steps in the development and evaluation of computer models. As a result of the SuperMUSE hardware and software technology, EPA can now better investigate new and existing UA and SA methods. EPA can also more easily achieve UA/SA of complex, Windows-based environmental models, allowing scientists to conduct analyses that have, to date, been impractical to consider.

Databases

  • Environmental Geophysics
    This website beta version contains information on geophysical methods, references to geophysical citations, and a glossary of geophysical terms related to environmental applications.
  • HELP
    A quasi-two-dimensional modeling program that simulates water movement into and out of landfills based on a waste management system's particular design. The user can conduct water-balance analyses of solid waste disposal and containment facilities.
  • MULTIMED
    A one-dimensional, steady-state model used to predict the concentration of contaminants migrating from a waste disposal facility via the subsurface, surface water, and air pathways to receptor sites.
