- Swan (Simulating WAves Nearshore) 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. See a short overview of the model features of Swan. To download the latest version of SWAN, either the source code or the Set-up Wizards for Swan, visit the Swan website or click on the SourceForge page.
Swan focus on the computation. Input for Swan is a batch-file, output is presented as a set of data files. The user is supposed to make the input command file himself and process the output data files separately. To help user with this, a number of Graphical User Interfaces (GUI's) are available via different parties (like Digital Hydraulics of via Deltares [Delft3D])SwanOne is an easy to use one-dimensional graphical interface (GUI) for Swan. It uses the full Swan program, however it uses the program in 1D mode. This means that SwanOne assumes parallel depth contours. This makes operations much easier. But all calculations are fully 2-D calculations, so SwanOne includes refraction, directional spectra and directional spreading. A paper on the use of SwanOne has been presented at the ICCE 2008 in Hamburg (download paper).
Note that SwanOne uses an exe-version of Swan and Matlab; therefore these programs cannot be run on an Apple computer.
The SwanOne suite contains three programs:
- SpecGen, a program to make a (2D) input spectrum file based on 2 different Jonswap spectra. This can be used for example if conditions where simultaneously a wind waves and swell waves from different directions occur.
- SwanOne, the GUI for Swan to execute the Swan calculation and perform some post processing
- SwanOneSed, to calculate the sediment transport and its distribution along a coastline. This program uses the output of Swan to determine the wave conditions at any point of the profile and calculates the local sediment transport using the Van Rijn formula.
All three programs have been made in a Matlab environment, and can be run in Matlab. The Matlab scripts are base on the 2018 version of Matlab. However, also standalone versions are available. In order the run the standalone version, you have to install the Matlab Compiler Runtime (MCR). You first have to download the MCR and install it. For SwanOneSed the installer is included in the in the installation package. Notice that the Installer is quite large, both downloading and installing takes quite some time. You need administrator rights on your computer to install the MCR.

When you run Matlab scripts in the Matlab environment start with SpecGen.m, SwanOne.m or SwanOneSed.m. In the standalone version you start with SpecGen.exe, SwanOne.exe or SwanOneSed.exe. Note that starting these executables takes some time (Matlab has to start up, during this time you see nothing happening, be patient).
Do not start Swan.exe, this is the executable of Swan itself, you can not run this executable directly. However, Swan.exe has to be in the same directory as SwanOne.exe.
For running SwanOne.exe you unpact the zipfile, you do not need administrator rights, you can directly run it after installation. However:
- You should not place SwanOne.exe (i.e. unpack the zipfile) in a directory with write protection, so not in ProgramFiles or ProgramFiles(x86).
- Starting up SwanOne requires quite some memory. On a computer with limited memory, this takes time, especially when also an other memory consuming program is running on the background (i.e. your virus-checker). It may take some time before SwanOne shows on the screen. If you want, you can check activity with the task manager (via Cnt-Alt-Del).
Swan and SwanOne software can be used freely under the terms of the GNU General Public License (see Copyright and Liability). However, for any use of the Swan source code in your environment, proper reference must be made to the origin of the software!
SWASH (an acronym of Simulating WAves till SHore)
is a non-hydrostatic wave-flow model and is intended to be used for
predicting transformation of surface waves and rapidly varied shallow
water flows in coastal waters. The governing equations are the nonlinear
shallow water equations including non-hydrostatic pressure and provide a
general basis for describing complex changes to rapidly varied flows
typically found in coastal flooding resulting from e.g. dike breaks and
tsunamis, and wave transformations in both surf and swash zones due to
nonlinear wave-wave interactions, interaction of waves with currents,
and wave breaking as well as runup at the shoreline.To get an impression
of the current capabilities of SWASH you may want to click on http://swash.sourceforge.net/examples/examples.htm.
Recently the SWASH team at Delft University published a beta version of SWASH 1.02 under the GNU public license to http://swash.sourceforge.net. By providing the open source SWASH code that can be freely redistributed and modified, we hope to encourage everyone to further improve the science and configuration of the model. Any feedback is welcome! For more information including an overview of the features of SWASH go to http://swash.sourceforge.net
Probabilistic calculations can be done with VaP or with Matlab scripts. The program VaP makes probabilistic calculations of any type of function. VaP has been developed by ETH-Zürich.Link to a zipfile with an installation file for the student version of VaP. The disdavantage of VaP is that you can enter your Z-function only as one single line. VaP only works on 32 bit computers.Prob2B and simple manual. For repair of the 2015 version, click here. For background info and download outside TU Delft, go to the TNO website
TU Delft developed in cooperation with EMS in Durban, South Africa software for the processing of the data from their wavelogger. This software is available as Matlab scripts,and can be downloaded in a zipfile. Background info on this software is availbale in Comm. on Hydraulics 13-01
Small program to calculate the required height of a dike (in Dutch).
This program only incorporates the hydraulic load, no geotechnical check
is done. The spreadsheet on which this can be simulated can be
Note: left click will execute the program in your browser, right click allows you to download the file simulator.swf. You may store this file locally (using "save link as") and run it later by opening it as a local file in your browser.
Latipas (Lathan Pasung Surut) is a one-dimensional tidal program
to calculate tidal levels and tidal currents when the tidal constituents
at the boundaries of the model are known. Latipas.exe is a executable
program (no installation required). A quick manual is included;
this manual contains all necessary information, but it is recommended
for the user to make some test runs to build up experience. The input
file for latipas is a .gjs file. Some examples are added to this folder.
New .gjs files can be made inside the latipas program, by starting with
the heading new.
Latipas can be used for three purposes:
- Computation of tidal curves for a single station, given the tidal constituents for that station. In such a case for branch 1 a ficitive length can be entered in the fle (see examples HvH, Vlisssingen, DoSon, Banyuwangi).
- Computation in a tidal channel (which can be very wide) which is closed at one end; latipas provides than waterlevels at all points and discharges in all channels (see example Schelde, Schelde3, Zeeschelde).
- Computation in a tidla channel with two open boundaries; then of course the tidal constituents have to be given at both sides (see example Vliss-Antw, Surabaya).
Latipas (Lathan Pasung Surut) has been drafted by Gerrit Jan Schiereck of TU Delft for educational use for universities in Indonesia, but it can be applied anywhere in the world. The work was funded by the Royal Dutch Embassy in Jakarta via Nuffic. The program is free to use and can be downloaded here.
LOCKFILL is a quick tool enabling the assessment of a shipping lock's performance, in terms of levelling times and longitudinal forces on vessels. The program allows the calculation of filling and emptying through the lock head, using various levelling systems. A graphical user interface allows easy input and shows the computational results in graphs and key indicators
