Riparian zones are also important for the fish that live within rivers, such as brook and charr. [28] Impacts on riparian zones can affect fish, and restoration is not always sufficient to recover fish populations. [29] [30] They provide native landscape irrigation by extending seasonal or perennial flows of water. [31]
Riparian-zone restoration is the ecological restoration of riparian-zone habitats of streams, rivers, springs, lakes, floodplains, and other hydrologic ecologies. A riparian zone or riparian area is the interface between land and a river or stream .
The term riparian comes from the Latin word ripa, 'river bank'; technically it refers only to areas adjacent to flowing bodies of water such as rivers, streams, sloughs and estuaries. However, the terms riparian forest and riparian zone have come to include areas adjacent to non-flowing bodies of water such as ponds, lakes, playas and reservoirs.
Streambed Zone The streambed zone of the riparian area is linked closely to Zone 1. Zone 1 provides fallen limbs, trees, and tree roots that in turn slow water flow, reducing erosional processes associated with increased water flow and flooding. This woody debris also increases habitat and cover for various aquatic species.
Flow modification can occur as a result of dams, water regulation and extraction, channel modification, and the destruction of the river floodplain and adjacent riparian zones. [76] Dams alter the flow, temperature, and sediment regime of lotic systems. [6] Additionally, many rivers are dammed at multiple locations, amplifying the impact.

A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
Desert riparian is a North American desert vegetation type (or biome) occurring in the bottoms of valleys, canyons, and other watercourses that have water at or near the surface most of the year. [1] The visual character is of large, lush, perennial green trees surrounded by dry desert vegetation and soil coloration. [ 1 ]
