The wetlands data layer is increasing in size each year primarily due to existing analog data being converted to vector or raster images. Contributed data from the U.S. Army Corps of Engineers Regulatory Database (ORM2), [10] other federal, state and local organizations is also increasing. More and newer data will need to come from other ...

Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.

The National Wetlands Inventory (NWI) was established by the United States Fish and Wildlife Service (FWS) to conduct a nationwide inventory of U.S. wetlands to provide biologists and others with information on the distribution and type of wetlands to aid in conservation efforts. To do this, the NWI developed a wetland classification system ...
Mitigation banking is a market-based system of debits and credits (used primarily in the United States as part of its "no net loss" policy) that involves restoration, creation, or enhancement of wetlands to compensate for unavoidable impacts to a wetland in another location. [1] It involves a system of mitigation banks, sites where projects to ...
Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).
