Abstract

HydroMET-EO (Hydrologic Model Evaluation Tool - Earth Observation) is the first-of-its-type desktop-based semi-automatic software designed for Soil and Water Assessment Tool (SWAT) hydrologic model. In its current version, HydroMET-EO harmonizes EO datasets of evapotranspiration, Leaf Area Index, and Soil Moisture from varying sources and resolutions to SWAT’s structure and time-step, enabling subbasin-level evaluation of model outputs. Guided by a user-friendly graphical interface with reproducible workflows, statistical metrics, and visual aids, HydroMET-EO streamlines EO integration and thus advances how we typically evaluate the accuracy and physical consistency of hydrologic models and watershed management decisions. Our case studies highlight the tool’s effectiveness, demonstrating that models calibrated solely on streamflow data, despite excellent performance, may fail to capture other critical hydrologic processes.

Here we provide HydroMET-EO software executable, a user guide, and an example SWAT project with pre-processed EO data.
