Procedural Documents

Classification:
The hydrogeomorphic classification of wetlands is intended to lay a foundation for and support ongoing efforts to develop methods for assessing the physical, chemical, and biological functions of wetlands.
Brinson, M.M. 1993. A Hydrogeomorphic Classification for Wetlands. U.S. Army Corps of Engineers, Waterways Experiment Station, Vicksburg, MS, USA. Technical Report WRP-DE-4, U.S. Army Engineer Waterways Experiment Station, Vicksburg, MS.
Approach:
The approach includes a development and an application phase. The assessment procedure, as the final product, can be used to compare project alternatives, determine impacts, calculate mitigation requirements, etc.
