The mathematical modeling techniques used to predict atmospheric dispersion of denser-than-air gases in the Ooms and DEGADIS models are briefly summarized. The Ooms/DEGRADIS model was written in FORTRAN with specific intent for compilation and execution on a Digital Equipment Corporation VAX computer. The Ooms model describes the release and subsequent dilution and trajectory of an elevated gas jet as a gas plume. If the plume falls to ground level, DEGADIS describes the resulting ground-level plume. DEGADIS can also be used to describe the release and dilution from a low-momentum, ground-level release. The necessary model-input information to simulate a denser-than-air gas release is summarized. Example simulations of steady-state and transient release and guidelines for installation of the models are included. The Ooms and DEGADIS models are listed along with certain program variables and diagnostic messages.
