3.0

Installation

1. Install QGIS 3.34

If you intend to use the new gwflow module then install 3.34.6, not 3.34.7, as the latter prevents gwflow working. This can be found from the QGIS all releases page.

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 3.34.6 is recommended (see above note about gwflow). Use the default folder C:\Program Files\QGIS 3.34.n as the installation folder. See the QSWAT+ manual for further instructions.

  • MacOS and Linux only: users will need to install openmpi separately.

    • MacOS: run brew install openmpi from a terminal.

    • Linux Ubuntu: run sudo apt-get install openmpi-bin from a terminal. Package name may vary with distribution.

2. .NET Runtime 6.0

If you plan to use SWAT+ Toolbox, please install .NET Runtime 6.0 from Microsoft. Find the ".NET Runtime 6.0.x" heading, and choose the appropriate Windows installer (usually x64).

3. SWAT+ 3.0 Installer

This release includes SWAT+ rev. 61, QSWAT+ 2.5, SWAT+ Editor 3.0, and SWAT+ Toolbox 2.0 (Windows only). To install the SWAT+ model and interface components, please use an installer linked below for your operating system. The installer is for 64-bit machines. Administrator privileges are not required for personal installations (but Mac requires use of sudo).

*For Linux and MacOS, the optional SSURGO/STATSGO soils and WGN databases should be downloaded from the SWAT+ SQLite Datasets section below as they are not included in the installers. See detailed installation instructions for Linux and MacOS here.

Existing SWAT+ users should be sure to read the release notes thoroughly to see how the software updates affect your projects.

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
