DISPERSE...
The software is designed to predict the short term pollutant concentrations
directly downwind (x direction) of an elevated point source at specified
distances and as a function of atmospheric stalibility and wind
speed.
The model is based on the following assumptions:-
- Concentration profiles in the plume follow
the Gaussian distribution in the y direction and z direction.
- Constant mean wind speed and direction.
- Dispersion in the x direction is negligible
with the bulk transport by the mean wind speed.
- The pollutant is a stable gas or aerosol which
does not chemically react or settle out.
The Model allows selection of dispersion coefficients
based on:-
- Pasquill-Gifford for flat open rural areas.
- McElroy-Pooler for built up urban areas.
Atmospheric stability classes A, B, C, D, E, F can be selected as
desired.
The design wind speed for the geographical area is used by the program.
