3D - view of the grid generated along with the terrain feautures.

From the above two pictures it is clear that ground level concentration contours of SO2 during emmission and also after emmission is less in the area shown in picture.

This picture explains the ground level concentration contours of SO2 after the end of the release.

3D-view of the computational domain with terrain feautures. This picture explains the location of the source, buildings and waterbodies in the domain with respect
to north. SO2 is the pollutant taken up for this study.

The iso-surface concentrations of the pollutant SO2 is shown for the complex computational domain.

Wind field is shown for the first plane at 12th minute. This explains the wind speed and direction in the vicinity of the
buildings, sources and waterbodies

This explains the ground level concentration contours of SO2 for the complex terrain at 12th minute. It is also clear from the picture that the source is still alive.
