Wade Hurt taught hydric soils classes [5] for soil science undergraduate and graduate students as well as environmental professionals. Classes teach theoretical, morphologic, and regulatory criteria used for delineating wetlands, siting septic drain fields, and identifying seasonal high water table elevation.

Determining the boundary of wetland, whether jurisdictional under sections 404 or 10, or not jurisdictional but still meeting the technical definition of a wetland, that is having the soils, vegetation and hydrology criterion met is called a "wetland delineation", and generally is performed by college graduates with natural science or biology ...
Even in the computer era, manual watershed delineation is still a useful skill, in order to check whether watersheds generated with software are correct. [1] Instructions for manual watershed delineation can be found in some textbooks in geography or environmental management, in government pamphlets, [4] [5] or in online video tutorials. [6]
This was under the Executive Order 11990. George H. W. Bush’s administration in 1989, emphasized three elements on its policy: strengthening the wetland conservation and acquisition measures, revising the delineation manual, and improving and streamlining the wetlands regulatory program. [8]

[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". [15]
Landscape ecology has been cited as a contributor to the development of fisheries biology as a distinct biological science discipline, [51] and is frequently incorporated in study design for wetland delineation in hydrology. [39] It has helped shape integrated landscape management. [52]
Wetlands are areas of land submerged in water near both terrestrial and aquatic systems. They are highly diverse and are classified by the United States Fish and Wildlife Service into five categories: "The term wetland includes a variety of areas that fall into one of five categories: (1) areas with hydrophytes and hydric soils, such as those commonly known as marshes, swamps, and bogs; (2 ...
