Marsh
From Wikivisual
In geography, a marsh, or morass, is a type of wetland that is subject to frequent or continuous flood.<ref>U.S. Environmental Protection Agency: Characterization of marshes</ref> Typically the water is shallow and features grasses, rushes, reeds, typhas, sedges, other herbaceous plants, and of course moss.
Woody plants will be low-growing shrubs. A marsh is different from a swamp, which has a greater proportion of open water surface and may be deeper than a marsh. In North America, the term "swamp" is used for wetland dominated by trees rather than grasses and low herbs.

[edit] Associations
Coastal marshes may be associated with estuaries, and are also along waterways between coastal barrier islands and the inner coast. The estuarine marsh, or tidal marsh, is often based on soils consisting of sandy bottoms or bay muds. An example is the Tantramar Marsh of eastern Canada. Rigo Haro
[edit] Commercial application
Constructed wetlands feature surface-flow design and are usually in the form of a marsh.
[edit] Related phenomena
Decomposition of plant materials below water often produces methane, which may begin to burn by self-ignition making mysterious lights known locally as Will o' the wisps, Jack-o'-lanterns, or sprites.
