XZ-Planes (perpendicular to ground surface):

In such a case, the program window is a XZ-plane (perpendicular to the ground surface). A pollutant point source (stack) is represented by a small square. In the Status bar at the bottom, we have X,Y and Z coordinate values in meters and data on our environmental system. Point the mouse where you want in the program window and the X,Y and Z values will be shown in the status bar at the bottom. On the left bottom corner, a text box appears: the pollutant concentration value (micrograms per cubic meter, ug/m³). Point the mouse where you want in the program window and the concentration value will be shown in the text box. The pollutant concentrations will be calculated in a perpendicular plane to the ground surface (XZ-Plane). The plane height will be determined by the user (y_r).

All the points of the XZ-Plane will be to a y_r height. The y_r value is chosen by the user before the calculation. We will be able to make many calculations considering different plane heights. The different plane heights will be determined by the user (y_r values). In this way, the physical form of the pollutant plume can be studied.

Example 2:

Both XY-Calculation and XZ-Calculation have been used in our simulation. In this way, the physical form of the pollutant plume can be obtained. Calculation in both XY-plane (parallel to ground surface) and XZ-plane (perpendicular to ground surface). The fucshia squares represent three point sources (stacks). The red colour represents high pollutant concentrations. Pollution map of Nitrogen oxides (NOx) produced by en industrial stack. The wind angle is 0 degrees (N), the wind velocity is  5 m/s and the pollutant flow rate is 1g/s. The fucshia squares represent the point sources (position of the stacks).  We have a three-dimensional image of the pollutant plume with these two computer screens.

Pollution map produced by continuous discharge in this region. Top: the orange horizontal line indicates us the position of the XZ-Plane. Bottom: The fucshia line  represents a point source (stack). The red colour represents high pollutant concentrations.
