Monitoring the Water Quality Benefits of a Triangular Swale Treating a Highway Runoff
Publisher: ASCE
Abstract: Swales are among the most commonly used stormwater control measures (SCMs) worldwide. In 2009, the North Carolina DOT constructed a grassed swale in Knightdale, North Carolina, in the right-of-way of Interstate 540 near ...
Nutrient and Sediment Reduction through Upflow Filtration of Stormwater Retention Pond Effluent
Publisher: American Society of Civil Engineers
Internal Water Storage Enhances Exfiltration and Thermal Load Reduction from Permeable Pavement in the North Carolina Mountains
Publisher: American Society of Civil Engineers
Abstract: Thermally-enriched stormwater runoff can negatively impact coldwater streams and their associated ecosystem services. The introduction of local and federal guidelines specifically targeting urban runoff temperature in the ...
Effect of Urban Catchment Composition on Runoff Temperature
Publisher: American Society of Civil Engineers
Abstract: Urban runoff adversely impacts cold-water stream environments due to sporadic fluxes of thermally enriched runoff. This adversely impacts tourism in regions that support trout and salmon streams. Research on storm water ...
Occurrence and Concentration of 6 Metals and 28 Organic Micropollutants in the Forebays of Bioretention Facilities
Publisher: American Society of Civil Engineers
Abstract: Pollutant loads in urban runoff from anthropogenic sources contribute to degradation of downstream waters. Cities are turning toward green infrastructure to manage urban stormwater. Bioretention is popular as green ...
Hydrologic Performance of Regenerative Stormwater Conveyance in the North Carolina Coastal Plain
Publisher: American Society of Civil Engineers
Abstract: Regenerative stormwater conveyance (RSC) is an open channel, sand-filtering system composed of a series of shallow aquatic pools, riffle weirs, native vegetation, and underlying media beds. Surface runoff entering an RSC ...
A Simple Infiltration Test for Determination of Permeable Pavement Maintenance Needs
Publisher: American Society of Civil Engineers
Abstract: Permeable pavements allow stormwater to pass through the pavement surface, filtering out sediment and debris; over time, regular preventative maintenance will be needed to maintain the pavement surface infiltration rate ...
Implementation and Maintenance of Floating Treatment Wetlands for Urban Stormwater Management
Publisher: American Society of Civil Engineers
Abstract: The floating treatment wetland (FTW) is an innovative hydroponic device which can be installed on the surface of a stormwater retention pond to improve its pollutant removal efficiency. Limited full-scale experiments have ...
Retrofitting Residential Streets with Stormwater Control Measures over Sandy Soils for Water Quality Improvement at the Catchment Scale
Publisher: American Society of Civil Engineers
Abstract: Impervious cover (IC) has been shown to increase runoff volumes, peak discharges, and pollutant loads to streams, which can lead to degraded water quality and biological integrity. Stormwater control measures (SCMs) have ...
Field Evaluation of Storm-Water Control Measures for Highway Runoff Treatment
Publisher: American Society of Civil Engineers
Abstract: The thousands of kilometers of highways in North Carolina have the potential to generate large amounts of storm-water runoff. Thus, investigation of storm-water control measures (SCMs) for these somewhat unique linear ...
