SLAB View is a graphical user interface for the SLAB model - an atmospheric dispersion model for denser-than-air releases. SLAB View is an ideal tool to predict hazardous zones and potential impacts of accidental releases.
SLAB View shows you how the release develops over time, as well as what the total footprint of the release will be.
SLAB View can model continuous, finite duration, and instantaneous releases from four types of sources:
- a ground-level evaporating pool
- an elevated horizontal jet
- a stack or elevated vertical jet
- and a ground-based instantaneous release
Features
Key Features
The SLAB model was developed in the 1980's by Lawrence Livermore National Laboratory (LLNL), with financial support from the Department of Energy (DOE). The SLAB model is currently distributed by the US EPA
Integrated Graphical User Interface
Fully integrated interface combining easy to use graphical tools, seamless model run, and automated contouring and posting of results.
Maximum Concentration Graphs
SLAB View automatically generates graphs displaying the Maximum Concentration Along the Centerline for all the meteorological conditions being modeled. You can specify the Level of Concern (LOC) for the chemical being modeled to be shown in the graph (indicated in this image as a red line).
3D Visualization
Watch the plume disperse in three dimensions using the 3D View option. Understanding how a release spreads has never been easier. SLAB 3D allows you to create animations of plume migration that can be incorporated into most presentation packages.
Export to Google Earth
This exciting feature allows you to export the footprint and or puff of the source spill into Google Earth giving you a more realistic image of where the spill will impact surrounding areas.
Support for Several Base Map Formats
SLAB View has support for a variety of image and base map formats allowing you to setup your model with confidence and easy visualization and identification of the location of your spill area. Supported base maps include: Bitmap, DLG, DXF, JPEG, LULC, MrSID, Shapefile, and TIFF/GeoTIFF.
Graphical and Output Options
SLAB View provides you with full control of the appearance of your footprints and puffs. You can specify the footprint levels (ppm) to be displayed, which colors to use, line thickness, and much more.
Extensive Chemical Database
SLAB View has an extensive database of chemicals that can be modeled, including their properties. User defined chemicals can also be added.
Multiple Release Types
SLAB View models several different release types such as horizontal and vertical jet, evaporation pool, and instantaneous or short duration evaporation pool.
