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.
