Automated Model Creation
Build SWAT+ models with high resolution hydrographical data in minutes instead of days with SWATGenX platform, which handles everything from data acquisition, GIS project creation, and model generation.
About SWATGenX
Watershed decision support: hydrologic modeling, flood analysis, and basin screening for USGS stations and HUC8 watersheds—through automation and open national datasets.

Mission
SWATGenX democratizes hydrological modeling and flood risk assessment by providing a watershed decision support platform: researchers, practitioners, and students can screen USGS streamgages and HUC8 basins, run flood and floodplain workflows, and order SWAT+ models from one workspace. Our mission is to accelerate discovery and informed water management through automation, national datasets, and open-source technologies—making advanced tools accessible regardless of prior GIS expertise.
SWATGenX
SWATGenX automates SWAT+ model creation for USGS streamgage stations and for HUC8 watersheds from the Watershed Explorer. SWATGenX employs QSWAT+ and SWAT+ Editor in an automated pipeline (it is not an alternative to those tools). Hydrographical data draws on NHDPlus HR (millions of reaches). Typical setup uses a 30 m DEM and 250 m land surface (NLCD/gSSURGO) for automated GIS and model inputs.
Flood Risk Analysis
From the same Watershed Explorer, SWATGenX provides real-time flood risk classification and on-demand floodplain analysis for 16,000+ USGS stations, with parallel HUC8-level screening and reporting. Streamflow is compared to Log-Pearson Type III return-period thresholds; 24-hour precipitation uses NOAA MRMS against PRISM climatology. Floodplain mapping uses Google Earth Engine DEMs; population analysis uses USGS governmental boundaries; results include map layers and PDF reports.
Key Features
Flood & watershed screening
Monitor flood risk across 16,000+ USGS stations and screen HUC8 watersheds. Run floodplain mapping, population analysis with governmental overlays, cropland/stream layers, and PDF reports from the Watershed Explorer.
Project Timeline
Project Inception
2023SWATGenX was conceptualized as a tool to automate the creation of SWAT+ models for any USGS streamgage station with high resolution hydrographical data.
SWATGenX Development
2024SWATGenX was developed as a proof of concept to demonstrate the feasibility of integrating high resolution hydrographical data into SWAT+ models.
Platform Deployment
2025SWATGenX is now available as a web application, allowing users to create hydrological models in a user-friendly interface.
Decision support workspace
2026Flood risk, floodplain, HUC8 workflows, and SWAT+ ordering unified in the Watershed Explorer.
