Abstract:

The Hydrogeomorphic HGM Approach is a collection of concepts and methods for developing functional indices and subsequently using them to assess the capacity of a wetland to perform functions relative to similar wetlands in a region. The approach was initially designed to be used in the context of the Clean Water Act Section 404 Regulatory Program permit review sequence. This Regional Guidebook a characterizes the Headwater Slope wetlands in southern Mississippi and Alabama, b describes and provides the rationale used to select functions for the Headwater Slope wetland subclass, c describes model variables and metrics, d describes the development of assessment models, e provides data from reference wetlands and documents their use in calibrating model variables and assessment models, and f outlines protocols for applying the functional indices to the assessment of wetland functions.
