SWAT+ is relatively new, and there are not so many tools to carry out model analysis and calibration. SWAT+ Toolbox is a free tool that allows the user to perform sensitivity analyses, calibration and more. The software has been written in C# and is available for the Windows operating system. We are still exploring how to bring this to Linux and Mac through .Net Core and the Avalonia project.
There are built-in updates through which more features, functionalities and bug fixes will are delivered. Check for updates as soon as you install.
