Short Description

The mathematical model SWAN (Simulating WAves Nearshore) is a third-generation wave model which was developed at the Delft University of Technology). SWAN computes random, short-crested wind-generated waves in coastal regions and inland waters. It accounts for the following physics:

  • wave propagation in time and space
  • shoaling due to spatial variations in bottom and current
  • refraction due to current and depth
  • frequency shifting due to currents and nonstationary depth
  • wave generation by wind
  • three- and four-wave interactions
  • whitecapping, bottom friction, and depth-induced breaking
  • transmission through or blockage by sub-grid obstacles
  • < wave induced setup
  • < diffraction

Simulation

The SWAN-model can be used as a stand-alone postprocessor. But it is also available as a part of the integrated modelling system Delft3D, where the wave computations can be directly coupled to the three-dimensional computations of hydrodynamics and transport processes.
