HEC-GeoHMS (Hydrologic Engineering Center-GeoHydrologic Modeling System) is a geospatial hydrology extension designed to work within Esri's ArcGIS platform. It provides a suite of tools to process digital terrain data (DEMs), delineate sub-basins, calculate watershed characteristics, and prepare the necessary inputs for HEC-HMS (Hydrologic Modeling System). Key Benefits of the 10.8 Version

As the official USACE HEC documentation explains, *“HEC‑GeoHMS is a GIS extension that provides the user with a set of procedures, tools, and utilities for the preparation of GIS data for import into HEC‑HMS and generation of GIS data from HMS output.”*The tool has been developed for users with limited GIS experience, though a background in hydrology and HEC‑HMS modeling remains essential. In practice, it turns a 2D DEM into a complete hydrologic data structure – a true timesaver when working with large, real‑world watersheds.
