Marshes also improve water quality by acting as a sink to filter pollutants and sediment from the water that flows through them. Marshes (and other wetlands) are able to absorb water during periods of heavy rainfall and slowly release it into waterways and therefore reduce the magnitude of floodin The pH in marshes tends to be neutral to ...
In the European Union (EU), since 2000, the Water Framework Directive (WFD) aims to achieve a number of objectives to improve water quality of lakes, rivers and coastal areas. [23] Key objectives are general protection of the aquatic ecosystem, protection of drinking water resources, and protection of swimmable waters. [ 23 ]
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.
Water efficiency: Constructed wetlands try to replicate natural wetland ecosystems. They are built to improve water efficiency and water quality. They also create wildlife habitats by using natural processes of plants, soils, and associated microorganisms. In these types of wetlands, vegetation can trap parts of suspended solids and slow down ...
Marsh grasses are generally planted up to the mean high tide line and in the water of the intertidal zones to break up wave energy, provide fish and wildlife habitat and improve water quality through upland runoff filtration. Studies show that plantings may show more success when administered in the spring in areas with existing marsh, mild ...
A simplified definition of wetland is "an area of land that is usually saturated with water". [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]
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.

Wetlands greatly influence the flow and quality of water, thus providing benefits to humans. They store and slowly release surface water, rain, snowmelt and flood waters, maintaining soil humidity during dry periods. But the most important service is the supply of clean water for drinking, agriculture, and industries.
