Wetland forms are determined by assessing wetland ecosystems surface morphology and pattern, water quality, relationship to open water, and the underlying mineral soil morphology. [8] Lastly, wetland types are determined by investigating the wetland ecosystems vegetation physiognomy.
Wetlands are characterized by water-logged soils and distinctive communities of plant and animal species that have adapted to the constant presence of water. This high level of water saturation creates conditions conducive to methane production. Most methanogenesis, or methane production, occurs in oxygen-poor environments.
"No Net loss" is the United States government's overall policy goal regarding wetlands preservation. The goal of the policy is to balance wetland loss due to economic development with wetlands reclamation, mitigation, and restorations efforts, so that the total acreage of wetlands in the country does not decrease, but remains constant or increases.
Clean Water Act protections are being jeopardized like never before, including for the Everglades, says Eyal Harel. Watershed moment: Supreme Court case puts our wetlands, water quality at stake ...
A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season".

There are a number of government agencies in the United States that are in some way concerned with the protection of wetlands. The top five are the Army Corps of Engineers (ACoE), Natural Resources Conservation Service (NRCS), Fish and Wildlife Service (FWS), National Oceanic and Atmospheric Administration (NOAA), and the Environmental Protection Agency (EPA).

SWAT (soil and water assessment tool) is a river basin scale model developed to quantify the impact of land management practices in large, complex watersheds.SWAT is a public domain software enabled model actively supported by the USDA Agricultural Research Service at the Blackland Research & Extension Center in Temple, Texas, USA.

Regulations to protect water quality and highway safety require that we create arbitrary boundaries within those gradients, but these boundaries are scientifically definable, and consist of areas where three criterion of the presence of hydric soils, the presence of wetland vegetation, and the presence of appropriate hydrology.
