Dynamic vegetation Roughness in the riparian zone
Vegetation in the floodplain plays an important role in dictating the hydraulics of an open channel river system. While vegetation is beneficial to the biological productivity of the river system, it can also increase flood risk due to increased channel roughness. Traditional means of predicting …

Vegetation Response After Invasive Tamarix Spp. Removal in the Riparian Zone and Semi-Arid Rangeland Ecosystems
… is often involved in restoration of Western, riparian habitat; however monitoring of vegetation after removal is often neglected and thus opportunity for adaptive management lost. To address this need, I have conducted three and half years of monitoring vegetation response after invasive …

In the Zone: the Effects of Soil Pipes and Dunes on Hyporheic and Riparian Zone Hydraulics and Biogeochemistry
… in stream corridors. The focus is hyporheic zones which form the interface between surface water and groundwater below and adjacent to stream channels, and riparian zones which form the interface between channels and adjacent uplands, both of which can attenuate pollutants. In this context, …

Extent And Distribution Of Montane Riparian Zone Vegetation And Representation In Protected Areas In The Sky Island Region Of The Southwestern United States
… most vertebrate biodiversity is dependent on riparian areas for all or some of their life cycles. Riparian vegetation is threatened by human impacts and climate change. Though riparian vegetation along rivers and major perennial streams is already mapped in this region, vegetation in ephemeral …

An analysis of the spatial and temporal changes in the Riparian zone of the Berg River in the vicinity of Hermon: implications for governance
Riparian zones broadly refer to the interface between terrestrial and aquatic systems. It is widely acknowledged that riparian zones provide a number of services including that of an ecological corridor for migration of animal species; a habitat; food for aquatic macro invertebrates in the form of …

Evaluation of Red Alder Mortality in the Little Creek Watershed Following the 2009 Lockheed Fire
… along a 2.16 km portion of the Little Creek riparian zone were assessed for mortality following the 2009 Lockheed Fire near Davenport, California. The study area was divided into burn severity zones and every red alder within the riparian zone was observed and assessed for mortality. Height, …

Location, location: Factors influencing greenhouse gas fluxes from the Mississippi Delta agricultural region
… of the agricultural landscape: farmland, riparian zone, and wetland habitat. This study assessed gas emission variability from the Mississippi Delta agricultural landscape and explored the effects of hydrology and hydrophytic vegetation on gas emissions.</p><p>Gas collection chambers were …

Hippopotami in a liminal space: a multi-species ethnography of Lake Tanganyika in Bujumbura
… Lake Tanganyika's freshwater ecosystem and riparian zone in Bujumbura, the capital city of Burundi, which affects the daily life and interactions between humans and hippopotami (hippo). Societal development agendas have favoured economic growth and infrastructural development with little …

An analysis of solute transport on a harvested hillslope in the southern Appalachian Mountains
… of forests. Also, the purported role of riparian buffers, where logging is restricted along stream channels, in retaining soil solutes is not well studied in the steeply sloping terrain of the southern Appalachian Mountains. I examined solute transport in a first-order watershed in the …

Himalayan Blackberry (Rubus armeniacus) Effects on Fish Habitat: Impacts from Riparian Zones Inundated with Himalayan Blackberry
… lotic reaches (channel width 1.5-5 m) having riparian zones inundated with invasive Himalayan blackberry (Rubus armeniacus) plants (test conditions) (3 sites) and reaches with a riparian zone consisting primarily of native vegetation (reference conditions) (5 sites). This thesis studied …

Environmental Factors Determining the Pre-Restoration Benthic Macroinvertebrate Assemblage In A Stream Used By Cattle
… from sediment, nutrients, and lack of a forested riparian zone. MU had a forested riparian zone, but still received nutrient and sediment inputs from upstream cattle grazing. Visual habitat assessments were performed in September 2006 and were compared to quantitative measures. Benthic …

Factors affecting the recruitment of riparian vegetation on the Ord and Blackwood Rivers in Western Australia
… involved in the recruitment and regeneration of riparian vegetation. As there has been a paucity of basic ecological studies on riparian vegetation in Australia, the project is broad in scope, and gives a general picture of the factors influencing, the regeneration of riparian vegetation and …

The effects of cattle exclusion on stream structure and function
… can be influenced by cattle grazing in the riparian zone due to sediment input, nutrient loading, and soil compaction, which lead to alterations of macroinvertebrate and microbial activity. Recently government programs, such as the Conservation Reserve Enhancement Program (CREP), have …

Sampling adequacy of freshwater mussel surveys and variation of mussel species richness in Illinois wadeable streams
… size, but increased with % of forests in the riparian zone and logs in streams. A second RF model was developed based on the same environmental variables to predict man-hours required for capturing 70% of all species (pesduo-R2 of 41%) at specific sites. I also showed that species richness at …

Characterization of hyporheic zone processes of a northern prairie stream
<p> A hyporheic zone occurs beneath and adjacent to streams where surface water and groundwater mix. This zone is known to be a reservoir for solutes and a habitat for interstitial organisms. Hyporheic zone boundaries in the Tongue River, North Dakota, were investigated through examination of the …

Ecohydrology effects of an invasive grass (Phalaris arundinacea) on semi-arid riparian zones
<p>"Riparian areas (floodplains) provide key ecological functions that are linked to the ecohydrology however; they are particularly susceptible to invasion by alien species. In much of the western United States, riparian zones are shifting from native woody and herbaceous species to invasive grass …

Mapping urban growth and investigating its potential impact on surface water quality in Chattanooga, Tennessee using GIS and remote sensing
… at watershed level scale including stream riparian areas. The obtained results show a net growth of 45.12 km2 of IS, 9.96 km2 being within 90 m of streams, a conversion of 6% of the study site’s land cover. A stream risk assessment study was conducted using the riparian zone percent …

Effect of riparian land use on the biotic integrity of fish assemblages in Black Creek, Chattanooga, Tennessee
… urban development, particularly along the riparian landscapes, could impact the stream's ecological health. I assessed fish assemblages (biotic integrity), water quality, instream habitat, and riparian land-use features at eight sites in Black Creek, May-June 2000. Water quality conditions …
