A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
An ecological definition of a wetland is "an ecosystem that arises when inundation by water produces soils dominated by anaerobic and aerobic processes, which, in turn, forces the biota, particularly rooted plants, to adapt to flooding". [1] Sometimes a precise legal definition of a wetland is required.
The Central and Southern Florida (C&SF) Project, [3] which was first authorized by the U.S. Congress in 1948, is a multi-purpose project that provides flood control, water supply for municipal, industrial, and agricultural uses, prevention of saltwater intrusion, water supply for Everglades National Park, and protection of fish and wildlife resources.
Water storage. Water storage is a broad term referring to storage of both potable water for consumption, and non potable water for use in agriculture. In both developing countries and some developed countries found in tropical climates, there is a need to store potable drinking water during the dry season. In agriculture water storage, water is ...
A constructed wetland is an artificial wetland to treat sewage, greywater, stormwater runoff or industrial wastewater. [1][2] It may also be designed for land reclamation after mining, or as a mitigation step for natural areas lost to land development. Constructed wetlands are engineered systems that use the natural functions of vegetation ...
Wetlands generally include swamps, marshes, bogs, and similar areas." [1] [2] [3] Wetlands can be valued in terms of their contributions to ecological, economic and social systems. Wetlands service these systems through multiple processes including water filtration, water storage and biological productivity. [4]
A tank cascade is a system of irrigation tanks in single or multiple chains where water from a higher tank flows into lower tanks. Examples of tank cascades include Sri Lanka's tank cascade system, [6] the Indian city of Bangalore's cascading lakes in the Varthur lake series, [7] and the Indian city of Madurai's Vandiyur tank cascade system.

In a bioretention system such as a rain garden, water filters through layers of soil and vegetation media, which treat the water before it enters the groundwater system or an underdrain. Any remaining runoff from a rain garden will have a lower temperature than runoff from an impervious surface, which reduces the thermal shock on receiving ...
