Mohid Studio


SWAN is a third-generation wave model, developed at Delft University of Technology, that computes random, short-crested wind-generated waves in coastal regions and inland waters.

Features of SWAN


SWAN accounts for the following physics: Wave propagation in time and space, shoaling, refraction due to current and depth, frequency shifting due to currents and non-stationary depth.

  • Wave generation by wind.
  • Three- and four-wave interactions.
  • Whitecapping, bottom friction and depth-induced breaking.
  • Dissipation due to aquatic vegetation, turbulent flow and viscous fluid mud.
  • Wave-induced set-up.
  • Propagation from laboratory up to global scales.
  • Transmission through and reflection (specular and diffuse) against obstacles.
  • Diffraction.

Output quantities

SWAN provides the following output quantities (numerical files containing tables, maps and timeseries):

  • One- and two-dimensional spectra;
  • Significant wave height and wave periods;
  • Average wave direction and directional spreading;
  • One- and two-dimensional spectral source terms;
  • Root-mean-square of the orbital near-bottom motion;
  • Dissipation;
  • Wave-induced force (based on the radiation-stress gradients);
  • Set-up:
  • Diffraction parameter;
  • And many more.
