Samples of animated results ana input-output information. | Hydrodynamic and Water Pollution Computer Program

Input

Input information is prepared conveniently in the graphical regime inside the program or may be imported:

Geometry and bathymetry of the area of computation.
Locations of the open boundaries and open boundary conditions.
Loading of pollutants from internal sources and from open boundaries.
Time/space variable wind and atmospheric pressure fields.
Bottom and ice roughness field.
Analytical expressions for empirical coefficients.
Initial conditions.

Using geographical maps of the computational domain as backgrounds makes pre- and post processing even more convenient.

Output
