In this system, wetlands are classified by landscape position, vegetation cover and hydrologic regime. The Cowardin system includes five major wetland types: marine, tidal, lacustrine, palustrine and riverine. Another common wetland classification system, used by the Army Corps of Engineers, was developed by Brinson and is described in A Hydrogeomorphic Classification for Wetlands Exit.
