1. Install QGIS 3.16

If you plan to use QSWAT+ to set up your watershed, please install QGIS 3 before installing SWAT+. It can be downloaded from the QGIS download page, where you should select the Long term release repository, and the 64 bit standalone installer. Version 3.16 is required. Use the default folder C:\Program Files\QGIS 3.16 as the installation folder. See the QSWAT+ manual for further instructions.

  • MacOS only: users will need to install openmpi separately. Run sudo brew install openmpi from a terminal.

The installer is for 64-bit machines. Administrator privileges are not required for personal installations (but Mac requires use of sudo).

Individual Component Installation

If you need to install QSWAT+ or SWAT+ Editor individually, grab the latest release of their respective installers from their source code repository downloads page.

SWAT+ Model (Command Line Executable)

The model itself is packaged with SWAT+ Editor and we recommend using the editor to modify your inputs and run the model. However, if you would like to download just the command line executable file, it is available below.

SWAT+ SQLite Datasets

On Windows we recommend using the SWAT+ Tools installer above for installing the SWAT+ datasets databases to their proper locations. However, for Linux and MacOS, or if you need to access these components individually, they are linked below:

These files should be placed in SWATPlus/Databases
