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.
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;
- Wave-induced force (based on the radiation-stress gradients);
- Diffraction parameter;
- And many more.
