HEC-EFM (Ecosystem Functions Model) is a specialized planning tool developed by the US Army Corps of Engineers (USACE) Hydrologic Engineering Center. It determines how ecosystems respond to changes in the flow regimes of rivers and wetlands.
The USACE National Ecosystem Restoration Planning Center of Expertise (ECO-PCX) has officially certified HEC-EFM and its spatial extension, HEC-GeoEFM, for national use in USACE planning and civil works feasibility studies. This certification ensures that the software is compliant with USACE policy, computationally correct, and theoretically sound. Core Analysis Framework
An ecosystem analysis using HEC-EFM is structured around three consecutive technical phases:
