Urban Riparian Zone

Intact riparian zones or vegetated areas adjacent to stream channels can serve several functions allan 1995.

Urban riparian zone. Riparian areas represent one of the most frequently found types of green area in the urban ecosystem. Provide organic matter for stream food webs. Urban riparian zone animals include mammals birds fish invertebrates and herpetofauna.

At all sites denitrification potential decreased markedly with depth in the soil pro file. With the right techniques these areas can be restored and reconstructed to improve habitat for fish and to stabilize the banks against erosion and gouging. Riparian zones are stream channels and corridors.

They provide a wide range of riparian functions e g. Riparian zones represent transitional areas occurring between land and freshwater ecosystems characterised by distinctive hydrology soil and biotic conditions and strongly influenced by the stream water. Riparian zones provide many environmental and recreational benefits to streams groundwater and downstream land areas.

Riparian zone and stream restoration. Urban and suburban riparian zones had higher no 3 pools and nitrification rates than the forested reference riparian zone which was likely due to more aerobic soil profiles lower levels of available soil carbon and greater n enrichment in the urban and suburban sites. They include the floodplain as well as the riparian buffers adjacent to the floodplain.

Riparian areas provide a range of essential ecosystem services including flood attenuation riverbank stabilization nutrient cycling groundwater recharge and providing habitats for plants and animals 1 2 with the possible exception of ecosystem services riparian areas increase the. Riparian zones are the areas bordering rivers and other bodies of surface water. Removal of riparian vegetation and channel hardening in an urban stream.

Several of the features of riparian zones are affected by surrounding urban land use which has important implications for the structure and function of biotic communities within these zones. In urban areas roads and other impervious surfaces can increase peak overland flows thus fundamentally altering the hydrologic disturbance regime for those systems. Many revetments have been built in urban riparian zones which has affected soil denitrification function of river riparian interface.
