QSWATMOD 1.3

QSWATMOD is a GIS-based modeling tool developed at Colorado State University that integrates the Soil and Water Assessment Tool (SWAT) with the MODFLOW groundwater model. It provides a streamlined, QGIS-driven workflow to build, couple, run, and analyze basin-scale simulations that capture interactions between surface water and groundwater. With QSWATMOD, hydrologists, water resource engineers, and watershed managers can assess how climate, land use, and management practices affect streamflow, recharge, groundwater levels, and related water resources outcomes.

Key capabilities:

• QGIS-based model setup using DEM, land use/land cover, soil, and climate data
• Consistent spatial discretization and parameter mapping between SWAT HRUs and the MODFLOW grid
• Two-way exchange of fluxes, including recharge, groundwater–surface water interactions, and management controls such as pumping and irrigation
• Scenario development and comparative analysis for planning and policy evaluation
• Built-in tools for post-processing, time series and map-based visualization, and reporting
• Documentation and example projects to accelerate learning and application

QSWATMOD helps researchers and practitioners perform integrated hydrologic modeling for decision support, enabling transparent, repeatable analyses of watershed responses to environmental change and water management strategies.

QSWATMOD is developed by Colorado State University. The most popular versions of this product among our users are: 1.2 and 1.3.
