Example 1:
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 water surface) and XZ-plane (perpendicular to water surface). The fucshia square represents a point source (position of the outfall pipe). The red colour represents high pollutant concentrations. The effluent flow rate is 0,15 m^3/s, the current velocity is 0,04 m/s and the current angle is 90 (E). The Buoyant Jet model has been used in the calculation. The fucshia square represents the vertical discharge source (outfall locations). We have a three-dimensional image of the pollutant plume with these two computer screens.
Pollution map produced by continuous discharge in this region. The Buoyant Jet model has been used. Top: the orange horizontal line indicates us the position of the XZ-Plane. Bottom: The blue horizontal line indicates us the position of the water surface plane. The fucshia square represents a point source (position of the outfall pipe). The red colour represents high pollutant concentrations.

Calculation in both XY-plane (parallel to water surface) and XZ-plane (perpendicular to water surface). The fucshia square represents a point source (position of the outfall pipe). The red colour represents high pollutant concentrations. The effluent flow rate is 0,15 m^3/s, the current velocity is 0,04 m/s and the current angle is 45 (NE). The Stratified model has been used in the calculation. The fucshia square represents the vertical discharge source (outfall locations). We have a three-dimensional image of the pollutant plume with these two computer screens.
BOD pollution map produced by continuous discharge in this region. The stratified model has been used. Top: the orange horizontal line indicates us the position of the XZ-Plane. Bottom: the orange horizontal line indicates us the position of the XY-Plane and the blue horizontal line indicates us the position of the water surface plane. The fucshia square represents a point source (position of the outfall pipe). The red colour represents high pollutant concentrations. The violet horizontal line (bottom) indicates us the position of the pycnocline (or thermocline) layer plane. We can see that there is no exchange of pollutants through the pycnocline layer.
