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.
LID emphasizes conservation and use of on-site natural features to protect water quality. 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]
Watershed delineation tools are also incorporated into some hydrologic modeling software packages. Software developers have also published libraries or modules in several languages (see list below). Many of these packages are free and open source, which means they can be expanded or adapted by those willing and able to write or modify code.
Watershed management is the study of the relevant characteristics of a watershed aimed at the sustainable distribution of its resources and the process of creating and implementing plans, programs and projects to sustain and enhance watershed functions that affect the plant, animal, and human communities within the watershed boundary. [1]
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 ...
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.
The Small Watershed Program is a program created under the Watershed Protection and Flood Prevention Act (P.L. 83–566), and 1 of 3 programs that are combined into the Watershed and Flood Prevention Operations Program. The Small Watershed Program is available in watersheds that are smaller than 250,000 acres (1,000 km 2). Currently, there are ...
This meant that the federal government would be able to purchase private land if the purchase was deemed necessary to protect rivers' and watersheds' headwaters in the eastern United States. [1] Furthermore, the law allowed for land acquired through this act to be preserved and maintained as national forest territory.
