Lakes Environmental - Version SLAB View 5.2 -Emergency Release Dense Gas Modeling Software
This software provides a graphical user interface for the SLAB atmospheric dispersion model, specifically designed for denser-than-air releases. It is an essential tool for predicting hazardous zones and assessing potential impacts of accidental emissions.
The platform visualizes how a release evolves over time and determines the total footprint of the incident.
Users can simulate continuous, finite duration, and instantaneous releases from four different source types:- A ground-level evaporating pool
- An elevated horizontal jet
- A stack or elevated vertical jet
- And a ground-based instantaneous release
The SLAB model was developed in the 1980`s by the Lawrence Livermore National Laboratory (LLNL), with financial support from the Department of Energy (DOE). The SLAB model is currently distributed by the U.S. EPA.
Fully integrated GIS-based interface combining easy to use graphical tools.
Visualize plume dispersion in 3D with SLAB 3D`s animation, ideal for presentations and analysis.
Export your buildings, sources, receptors and contours into Google Earth.
