QSWAT 2.0

QSWAT by WaterBase is a QGIS-based interface for the Soil and Water Assessment Tool (SWAT) that streamlines the setup, execution, and visualization of watershed-scale hydrologic and water quality models. It guides users through terrain processing, watershed and stream network delineation, and Hydrologic Response Unit (HRU) definition using land use, soil, and slope data. QSWAT builds complete SWAT projects, manages input data, runs simulations, and displays results directly within QGIS.

Key capabilities:

• DEM preprocessing and automatic watershed/subbasin delineation
• HRU creation with flexible land use, soil, and slope thresholds
• Configuration of climate inputs, reservoirs, point sources, and management practices
• Scenario management for baseline and what-if analyses
• Map-based and tabular visualization of flows, sediment, and nutrient outputs
• GIS-integrated, reproducible workflows for research and planning

Typical users include hydrologists, watershed modelers, consultants, and water resource agencies. QSWAT runs inside QGIS and works with the classic SWAT engine (e.g., SWAT2012). For SWAT+, WaterBase provides the separate QSWAT+ tool.
