Ambient data:

Ambient conditions are defined by the hydrographic conditions in the vicinity of the discharge. This Menu lists: Current.

Current.- DESCAR analyses, as all mixing zone evaluations, are usually carried out under the assumption of steady-state ambient conditions. If you click this command, the next dialog box is shown:

 

 

Depending on the used model, some data of the dialog box can be modified: Buoyant jet model or Stratified model (see calculation models).

Buoyant jet model: The necessary data in the Buoyant jet model is:

Water density (kg/m3): It is the density of the ambient water.

Current velocity ua (m/s): The average velocity of the water current. The admitted minimum velocity is 0,0001 m/s. A typical velocity can be of about 0,015 m/s.

Current angle (0 to 360): It is the horizontal angle of water current measured clockwise from the North (at the window top). For an outfall that is localized near the coast, the vector of the current is usually parallel to the coast.

 

Stratified model: The necessary data in the Stratified model is:

Coefficient of stratification (s-2): Г represents the stratification degree in the water

Г=-(g/ρa)(dρa/dh),

being g the gravity acceleration, g=9,81m/s2, ρa the ambient water density and h the depth. A typical value can be 0,00005 s-2 (The density of the seawater increases 5 kg each 1000m).

Stratified model: There are two options: Water is stratified and Water is not stratified. The stratification process usually happens in summer.
