QSWAT 1.5 was released Jan. 3, 2018.

Changes from version 1.4

  1. There are pre-defined print composition templates for displaying 1, 2, 3, 4 or 6 maps showing SWAT outputs.
  2. Single and multiple animations of SWAT outputs may be recorded as videos.
  3. Bug fixes:
    • possible reduction in HRU area when splitting a landuse into an existing landuse
    • possible multiple instances of delineation/HRU/visualisation forms

QSWAT Requirements

  • Microsoft Windows (any version, as far as we are aware)
  • Microsoft Access, as the interface uses an Access Database
  • Text editor and a tool to unzip archived files
  • SWAT Editor 2012.10.19 - requirements include:

Installation

  • Install QGIS by running QGIS-OSGeo4W-2.6.1-1-Setup-x86.exe. Use the default folder C:\Program Files\QGIS Brighton as the installation folder, or C:\Program Files (x86)\MQGIS Brighton on a 64-bit machine. Currently you must use the 32-bit version on 64-bit machines. It is also currently necessary to use version 2.6 rather than 2.8.  From now on we will use Program Files as a folder name, even though it will be Program Files (x86) on a 64-bit machine.
  • Install SWATEditor 2012 in its standard place C:\SWAT\SWATEditor. 
    • Refer to Appendix I of the QSWAT Manual for help updating a database.
    • Refer to the SWATEditor_Documentation.pdf in C:\SWAT\SWATEditor\SWATEditorHelp for help getting started.
  • Install QSWAT. This adds some files to the SWATEditor: a project database and a reference database in Databases, SWATGraph in the SWATGraph folder, and also stores the TauDEM executables in a new directory C:\SWAT\SWATEditor\TauDEM5Bin. The QGIS plugin QSWAT is put into the user's home directory in .qgis2\python\plugins\QSwat, which we will refer to as the QSWAT directory.
