Hydrogeomorphic classification for Great Lakes coastal wetlands
Dennis A. Albert, Douglas A. Wilcox, Joel W. Ingram, Todd A. Thompson
2005, Journal of Great Lakes Research (31) 129-146
A hydrogeomorphic classification scheme for Great Lakes coastal wetlands is presented. The classification is hierarchical and first divides the wetlands into three broad hydrogeomorphic systems, lacustrine, riverine, and barrier-protected, each with unique hydrologic flow characteristics and residence time. These systems are further subdivided into finer geomorphic types based on physical...
