==Short Description==

The [http://vlm089.citg.tudelft.nl/swan/index.htm mathematical model SWAN] (Simulating WAves Nearshore) is a  third-generation wave model which was developed at the [http://www.citg.tudelft.nl/ 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 [http://delftsoftware.wldelft.nl/ Delft3D], where the wave computations can be directly coupled to the three-dimensional computations of hydrodynamics and transport processes.
