Linking Stream Restoration Success with Watershed, Practice and Design Characteristics
In the United States, stream restoration is currently a billion-dollar industry. Though it is commonly used as a method for stream impact mitigation, Total Maximum Daily Load (TMDL) crediting, and stormwater management, there is little scientific knowledge defending stream restoration as an …

Improving Design Guidance for In-Stream Structures Used in Stream Restoration
Vane-type in-stream structures and step pool storm conveyance (SPSC) are more ecologically friendly alternatives to traditional stream channel stabilization and stormwater conveyance techniques. Vane-type structures have been widely accepted as elements of stream restoration projects and are …

An ecological evaluation of an urban stream restoration in West Chicago, Illinois
… as well as degradation to those resources. Streams in urban systems are often highly degraded and may require restoration to mitigate negative effects of urbanization and restore ecosystem function. In this study, I analyzed the physical habitat, water quality, macroinvertebrate community, …

Nutrient release potential during floodplain reconnection: Comparison of conventional and ecological stream restoration approaches
In the last few centuries, many streams in the eastern United States have been severely disturbed by land use change and are now disconnected from their original floodplain due to the aggradation of legacy sediment. Currently, stream-floodplain reconnection is advocated as a stream restoration …

Cumulative Impacts of Watershed-Scale Hyporheic Stream Restoration on Nitrate Loading to Downstream Waterbodies
… that must be solved at watershed scales, and stream restoration is increasingly implemented as a solution. Yet few studies evaluate the cumulative effects of multiple individual restoration projects on watershed-scale nutrient loading. We constructed a HEC-RAS model of stream restoration …

Assessment of Hyporheic Exchange at In-stream Restoration Structures on Savage River, Garrett County, Maryland
Previous studies have shown that in-stream restoration structures alter hyporheic exchange dynamics in restored channels; this study assessed hyporheic exchange at a recently constructed stream reach, including the effects of in-stream restoration structures. Hydrometric and thermal data were …

Cumulative Impacts of Stream Restoration on Watershed-Scale Flood Attenuation, Floodplain Inundation, and Nitrate Removal
… to quantify the cumulative impacts of multiple stream restoration projects within a single watershed on flooding and nutrient removal. Previous studies have quantified the effects of stream restoration on flood attenuation. However, our first study fills a substantial knowledge gap by evaluating …

Flow estimation for stream restoration and wetland projects in ungaged watersheds using continuous simulation modeling
More than a billion dollars are spent annually on stream restoration in the United States (Bernhardt et al., 2005), but the science remains immature. A promising technique for estimating a single or range of design discharges is the generalization of a parsimonious conceptual continuous simulation …

A Method for the Determination of Design Discharges for Urban Stream Restoration Projects in Northern Virginia
… volume and velocity from urbanization result in stream channel degradation (Hammer 1972; Henshaw and Booth 2000; Walsh et al. 2005; Leopold et al. 2005a; Poff et al. 2006). While stormwater management measures may be implemented to reduce the impact of stormwater runoff on streams, these …

Impact of Stream Restoration on Flood Attenuation and Channel-Floodplain Exchange During Small Recurrence Interval Storms
… along the river. Prior studies have shown that stream restoration can enhance flood attenuation, and increased exchange of water between the channel and floodplain can improve water quality. However, the effects of floodplain restoration during small and sub annual recurrence interval storms …

A Case Study of Northern California: An Evaluation of Stream Restoration and the Success of Increasing California's Native Salmonid Stocks
<p>Over the past decade, Stream Restoration has become a management tool in helping combat the degradation of our streams. This case study compares three watersheds in Northern California, the Klamath River Basin, Russian River Basin and Lower Putah Creek. The comparison determines whether or not …

Stream Habitat Characterized by Stage -Specific Flows and Three-Dimensional Geomorphological Complexity: Development of Ecological Criteria for Stream Restoration Design
In a low-gradient, third-order stream in East-Central Illinois, a new classification scheme for mesohabitat units was developed based on three-dimensional geomorphological complexity, and associated flow structures at low- and high-flow stages. In this two-tier classification scheme, the term …

The Development of a Stream Restoration Decision Support Tool for the County of Henrico Stream Assessment and Watershed Management Program
… and objectives vary, all seek to incorporate stream restoration project work. Decision support tools exist for many aspects of watershed and water resources management, however, there are currently no such tools to aid municipalities in their stream restoration efforts. This study details the …

Enhancement of Concretized Streams: Mill Creek
… has spurred much interest in ecological stream restoration. Billions of dollars are entering this field as societal and regulatory pressures are exerted upon municipalities and developers. Research suggests that stream restoration projects only consider aesthetics and economic growth as …

Channel geomorphology relationships for the Beaver Creek watershed
… to the construction of Corridor H, some of the streams will be disturbed from their present courses. Hence, stream restoration work for these streams is inevitable. It is important to develop a family of stream geometry curves that relate the bankfull parameters as functions of drainage area to …

Complementary Effects of In-Stream Structures and Inset Floodplains on Solute Retention
The pollution of streams and rivers is a growing concern, and environmental guidance increasingly suggests stream restoration to improve water quality. �Solute retention in off channel storage zones such as hyporheic zones and floodplains is typically necessary for significant reaction to occur. …

Assessment Of The Macroinvertebrate Assemblages From The Mesohabitats Of A Headwater Stream-Wetland Hydrologic Restoration In Eastern Kentucky
<p>The bulk of streams in the U.S. have been negatively impacted by anthropogenic disturbances and the streams of Kentucky are no exception. In recent decades stream restoration has become a common practice in order to improve habitat degradation resulting from land use practices such as …

Effects of beaver dam analogs on stream ecosystem function of Crab Creek, Washington State
… WA. Beaver dam analogs are structures placed in streams to mimic the ecosystem effects of beaver activity and are increasingly used as a stream restoration technique. The primary goals of placing these BDAs in the stream was to impound sediment and create a new floodplain at the currently incised …
