Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. [1] Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.
Restrictions on projects include: the size of the watershed must be 250,000 acres (1011 km²) or less; no single structure may provide more than 12,500 acre-feet (15,400,000 m 3) of flood water retention; no single dam may provide more than 25,000 acre-feet (31,000,000 m 3) of total capacity; and projects with costs greater than $5 million or ...
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.

This approach implements engineered small-scale hydrologic controls to replicate the pre-development hydrologic regime of watersheds through infiltrating, filtering, storing, evaporating, and detaining runoff close to its source. [1] Green infrastructure investments are one approach that often yields multiple benefits and builds city resilience ...
Watershed protection was also a major concern, especially in the Adirondacks; supporters of watershed conservation pointed to the creation of the Adirondack and Catskill Preserve in 1885 as a potential model for future forest preserves. However, over 200 congressional forestry bills introduced from 1871 to 1891 failed to pass; according to ...
[2] Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, [3] [4] and impluvium. [5] [6] [7] In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line.
Mississippi River Watershed. Conservation programs for the Mississippi River watershed have been designed to protect and preserve it by implementing practices that decrease the harmful effects of development on habitats and to overlook monitoring that helps future planning and management.
