SWAT+ Beginner (2 days)
This is course designed to introduce users to the SWAT+ model, review necessary and optional inputs, and familiarize the user with the QSWAT+ and SWAT+ editor interfaces. It is assumed that attendees have a working knowledge of QGIS. The course will not review basic concepts on QGIS usage prior to covering the SWAT/QGIS interface. SWAT+ workshop topics. $200 USD, or $150 for students.
SWAT+ Toolbox (2 days)
SWAT+ Toolbox is designed to work with the SWAT+ model. This workshop will focus on sensitivity analysis, model calibration, evaluation, and validation using SWAT+ Toolbox. The software is currently only available on Windows. You are encouraged to bring your own laptop but model data used in the workshop will be provided. $200 USD, or $150 for students.
SWAT+ Developer Workshop (1 day - 21 Oct.)
Join us for a hands-on full day SWAT+ Developer Workshop, where you'll dive into the SWAT+ model development workflow using GitHub. Bring your computer and datasets to actively participate in building and running the model. Learn how to contribute to the SWAT+ codebase by creating forks, making changes, and submitting pull requests. We'll cover key GitHub concepts like branching and collaboration to empower you to engage directly with the development community.
Both in-person and online 21 October 2025, approximately 09:00-17:00. Please bring your own laptop. We will contact you closer to the workshop date with a more detailed agenda and preparation instructions.

SWAT+ Soil Carbon Modeling using an Open Source Model Service and API (1-half day - 20 Oct.)
This 4-hour workshop on 20 October from 13:00-17:00 introduces a transparent, open-source soil carbon model, services, and APIs designed specifically for agricultural stakeholders. Our approach with SWAT+ offers transparency, reproducibility, and community-driven development, putting control back in the hands of farmers, researchers, and agricultural professionals. This condensed afternoon workshop combines technical insights with hands-on collaboration to identify data gaps, develop practical solutions, and create a collective strategy for advancing soil carbon modeling in your region and crops of interest. Whether you represent growers seeking accurate carbon quantification for supply chain and market programs, a researcher needing robust modeling tools, or an industry professional requiring reliable soil carbon data for your organization, you'll leave with actionable next steps, information about how to access the model platform, and connections to a growing community of agricultural carbon leaders. This is an opportunity to shape the future of agricultural carbon management while gaining early access to technology that's set to shift the paradigm for measuring, verifying, and optimizing soil carbon modeling across diverse farming systems.
The workshop will be offered online and in-person for a small fee of $100 USD, or $75 for students. Coffee break provided.
Note: The SWAT+ gwflow and APEX workshops have been canceled.
