SWAT Editor

Download SWAT Editor 2012.10.26 (August 2024). Remember to uninstall any previous versions before installing a new version.

SWAT Editor reads the project database generated by ArcSWAT or QSWAT, allowing the user to edit input files, execute a SWAT2012 model run, perform sensitivity, auto-calibration and uncertainty analysis. This is a standalone program and does not require GIS, thus helping users of ArcSWAT and QSWAT to share their project with others that do not have GIS or much experience with GIS in general.

Windows 11 Installation

SWAT Editor was originally built for older versions of Windows. If you try to install but get an error stating .NET Framework v2 is not installed, you need to install .NET Framework v3.5 (this replaces version 2). Please note that .NET Framework is entirely different software than .NET (without the word "framework").

In newer versions of Windows 11, this is a standalone installation and not through Windows Update or Feature Installation. Download .NET Framework v3.5 here and follow the instructions from Microsoft.
