TASC is a watershed scale model that converges terrestrial and aquatic carbon cycles at the watershed scale. It is based on the SWAT-Carbon model and has unique functions to assess impacts that agricultural management and climate change have on a wide range of processes and indicators, such as soil organic carbon storage, nitrous oxides emissions, freeze-thaw cycles/water temperature, and riverine carbon fluxes.

MapSWAT is an open-source QGIS plugin integrated with Google Earth Engine (GEE) that obtains and prepares SWAT+ input maps. It aims to help new or advanced users streamline the setup of their SWAT+ models. MapSWAT makes the preparation of SWAT+ input maps less error-prone, time-consuming and resource-intensive and facilitates model application in any study area worldwide. Additional information and the MapSWAT user manual and executable are available online. View reference paper.

Free, open source, graphical user interface for SWAT/SWAT+ calibration, parameter sensitivity/uncertainty analysis. For help see the user group and tutorial videos.

pySWATPlus is a Python library tailored for seamless interaction with Soil and Water Assessment Tool Plus (SWAT+). Empowering users to efficiently manage input and output files within Python environments, pySWATPlus streamlines data manipulation and calibration processes using pymoo.

SWAT+ Toolbox is designed to work with the SWAT+ model. You can use it for sensitivity analysis, model calibration, evaluation, and validation. The software is currently only available on Windows. There are built-in updates through which more features, functionalities and bug fixes will be delivered. Check for updates as soon as you install. Check the user documentation here. Older versions may be downloaded here.

The gwflow module for SWAT+ is a physically based spatially distributed method for simulating groundwater storage, groundwater head, groundwater flow, and groundwater inflows/outflows (groundwater-stream exchange, groundwater-tile exchange, groundwater-lake exchange, groundwater-soil exchange, groundwater pumping). When in use, this module replaces the original groundwater module of SWAT+.

Integrate SWAT+ and SWAT2012 models in modeling workflows in R

SWATdoctR is a collection of functions and routines for SWAT+ model diagnostics and calibration in R. The R package includes routines for a guided model calibration, functions for the evaluation of the model performance, as well as functions for the visualization and diagnosis of simulation outputs. For reference see the original publication.
