Jan 23, 2017 · Riparian areas absorb and dissipate water energy during floods and other high water situations. Water quality is also enhanced by other physical, chemical and biological processes, which are driven by the local ground and surface water. These processes, which occur in the soils and vegetation, assist in removing or lessening the impact of ...

Riparian zones absorb and store water during high flows, slowly releasing it during low flow periods. They help dissipate the energy, speed, and volume of floodwaters, reducing downstream damage. Recreational opportunities. Riparian areas are popular spots for recreational activities like hiking, canoeing, bird-watching, and others.
The term “riparian” is defined as "vegetation, habitats, or ecosystems that are associated with bodies of water (for example streams, springs or ponds) or depend on perennial or intermittent surface or subsurface water." Put more simply, riparian areas are the green ribbons of trees, shrubs, and herbs growing along watercourses.
Thus, streamside riparian areas are responsible for the dissipation of energy associated with flowing water. The flow resistance, or roughness, of a stream reach, caused by the physical configuration of its channel, streambanks, and floodplains as well as by the riparian plant communities, can be described by a roughness coefficient, such as Manning’s n (Leopold et al., 1964).
Nonfunctional: Riparian–wetland areas are nonfunctional when they clearly are not providing adequate vegetation, landform, or large wood to dissipate stream energy associated with high flows and thus are not reducing erosion, improving water quality, etc., as listed above. The absence of certain physical attributes,
Riparian areas also benefit humans. Healthy riparian areas can maintain or improve water quality and have both recreational and economic benefits. As flooding or runoff occurs, riparian vegetation reduces water velocity, captures sediment and filters the nutrients and pollutants (pesticides, heavy metal, etc.) that would otherwise run into a ...

Mar 1, 2019 · Appropriately managed riparian areas offer multiple functions related to improving water quality, biodiversity, and climate adaptation. First, riparian areas offer possibilities for protecting watercourses and lakes from inputs of sediments, nutrients, pesticides, and other contaminants by intercepting surface runoff, tile drainage, and groundwater from adjoining agricultural fields.
