Non-point source emissions

The DISPER model include algorithms to model line and area  sources, in addition to point sources. These non-point source options of the model are used to simulate the effects of emissions from a wide variety (conveyor belts, rail lines, area sources,…). The area source model is used to simulate the effects of fugitive emissions from sources such as storage piles and slag dumps.

In this application, the area and line sources (non-point sources) are represented by small many intervals (point sources). The program simulates the non-point sources solving each one of the defined intervals and calculating the total concentration. A great number of point sources simulates the geometry of these non-point sources.
