Welcome to the SWASH home page
|SWASH is a general-purpose numerical tool for simulating unsteady, non-hydrostatic, free-surface,
rotational flow and transport phenomena in coastal waters as driven by waves, tides, buoyancy and wind forces.
It provides a general basis for describing wave transformations from deep water to a beach, port or harbour,
complex changes to rapidly varied flows, and density driven flows in coastal seas, estuaries, lakes and rivers.
For more information about SWASH, see a short overview of
model features. This list
reflects on the scientific relevance of the development of SWASH.
To get an impression you may want to consider the examples or
The current version of SWASH is 4.01.
The release notes can be found here.
The ongoing development of SWASH aims to improve its skills and
performance and was made possible by numerous contributions from many researchers and users.
By providing this open source code, we hope to encourage everyone to further improve the science and
configuration of the model. Any feedback is welcome!

Yet, it has the same look and feel to SWAN, i.e. the way you need to specify
the input resembles to that of SWAN.
Hence, those users who are familiar with SWAN should be able to use SWASH without much effort.
It is recommended to carry out some available
test cases first to get acquaint with the program.
