The Hydrogeomorphic HGM Approach for assessing wetlands was developed by the U.S. Army Corps of Engineers as a procedure for assessing the capacity of a wetland to perform ecological functions. The Approach requires classification of wetlands based on geomorphic setting, water source, and hydrodynamics. The objective of the Guidelines for Guidebook Development is to provide detailed guidance on methods and procedures that have proven helpful in developing existing guidebooks. This document contains an overview of the HGM Approach how to classify and characterize wetland subclasses developing assessment models selecting reference wetlands and managing reference wetland data testing and calibrating models developing assessment protocols for using assessments validating assessment models and assessment application examples.
