Surface Water Assessment eNabler (SWAN) Version 4.0.1 Release Notes

Version 4.0.1 is a patch release of SWAN to accommodate further changes to the SWASH toolset and fix one bug.

Supported Tools Versions

  • MACRO Shell: 5.5.4
  • PRZM Shell: 4.3.1
  • TOXSWA Shell: 4.4.3
  • VFS Mod: 4.2.4


The provided SwanSetup.exe is used to install, uninstall and repair the application.

Application repair and uninstall can also be carried out in the usual way in Windows.

This installer will not remove previous versions of SWAN 3.

SWAN 4 can be installed alongside SWAN 3 if desired.

Changes Since Version 4.0.0

  • SWAN-34: Update supported PRZM from 3.2.1 to 4.3.1.
  • SWAN-34: Update supported TOXSWA from 4.4.2 to 4.4.3.
  • SWAN-36: Fixed a crash with pure aquatic metabolites.

Changes Since Version 3.0.1

  • The application supports the new TOXSWA file format associated with the TOXSWA Shell 4.4.2. The previous format is not supported and must be run with the latest version of SWAN 3. The application will report if you are using a project that requires SWAN 3.
  • The VFSMod version integrated into the application has been updated to version 4.2.4.
  • The application now explicitly states the configured SWASH Projects directory and warns if you select a project elsewhere.
  • The dry deposition grid has been improved to make it easier to copy values to other cells.
  • Fixed a possible crash and/or error message when proceeding with a project without run-off mitigation selected.
  • The application has been rebranded to make it obviously visually distinct from SWAN 3.
  • SWAN no longer repeatedly prompts about non-standard temperatures during a batch run. Warnings are now only issued when selecting a project.
  • A "portable" version of SWAN is available for the first time with this release.
  • Updated contact details for project personnel.
  • Reports from a run sometimes stated that VFSMod had been run even when it hadn't. This has been fixed.
  • The buffer width dropdowns have been altered to display more items on Windows XP machines.
  • Other minor cosmetic and usability fixes.
