DESCAR 3.0 Advantages:

Without considering the experience that the user possesses in programming languages or in the use of simulation tools, in few minutes he will be able to have the first results.

With this application you will be able to export your simulation results (BMP files). These images will contain the background picture (map) and your simulation results. Many programs and computer applications (AutoCad, 3d Studio, ArcView, MS Power Point, MS Word,... ) can import your saved BMP files.

The application uses two different mathematical models: Buoyant jet model or Stratified model. The Buoyant model is ideal for industrial discharges located in the proximities of the coast and in rivers, (using little depth). This model is based on a time-independent Gaussian equation which simulates the pollutant dispersion in the water. The Stratified model takes into account the formation of the pycnocline in the sea. This model is ideal for sewage discharges in the sea (using a lot of depth).

DESCAR 3.0 carries out temporal averages (daily, monthly or annual) so that you can calculate the concentration average in each point of the affected area.

Water pollution map of the heavy metal concentrations (Hg) produced by three point sources in this region. Each effluent flow rate is 0,15 m^3/s, each outfall angle is 180 (S), the current velocity is 0,015 m/s and the current angle is 90 (E). The Buoyant Jet model has been used in the calculation. The three fucshia squares represent the three different point sources (outfall locations). 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.
