Moisture Measurements as Performance Criteria for Extensive Living Roof Substrates
Publisher: American Society of Civil Engineers
Abstract: Extensive living roof substrate design to promote storm-water management while balancing structural load and maintaining
Effects of Postprocessing Decisions on Flow-Weighted Event Mean Concentrations
Publisher: American Society of Civil Engineers
Abstract: The sensitivity of an industry-defining stormwater quality metric, the flow-weighted event mean concentration (EMC), to nonstandardized calculation protocols was evaluated. Our objective was to explicate quantitative methods ...
Effect of Composition on Basic Properties of Engineered Media for Living Roofs and Bioretention
Publisher: American Society of Civil Engineers
Sources and Impacts of Uncertainty in Uncalibrated Bioretention Models Using SWMM 5.1.012
Publisher: ASCE
Abstract: Using the USEPA’s Storm Water Management Model version 5.1.012 (SWMM), a case study of a street right-of-way bioretention system (ROWB) configured as a storage node is compared against SWMM’s Low Impact Development (LID) ...
Phosphorus Leaching Behavior from Extensive Green Roof Substrates
Publisher: ASCE
Abstract: The substrate is the key component of a green roof system that directly influences the system’s stormwater mitigation performance; however, it is also identified as a potentially significant source of contaminants. It is ...
Assessing the Effects of Bioretention’s Engineered Media Composition and Compaction on Hydraulic Conductivity and Water Holding Capacity
Publisher: American Society of Civil Engineers
Abstract: Bioretention devices are often recognized as stormwater control measures (SCMs) that satisfy green infrastructure or low-impact development (LID) objectives. The hydraulic characteristics of filter media underpin effective ...
Quantifying Evapotranspiration Rates for New Zealand Green Roofs
Publisher: American Society of Civil Engineers
Abstract: Green roofs are an emerging storm-water management tool that has predominantly been analyzed for runoff volume reduction and peak flow mitigation. Little research has been completed on evapotranspiration (ET) in green roofs.
Multiyear Study on Phosphorus Discharge from Extensive Sedum Green Roofs with Substrate Amendments
Publisher: ASCE
Abstract: Green roofs are implemented for providing urban ecosystem services like stormwater management, but they have also been identified as a potentially significant source of phosphorus in the runoff, which may cause concern for ...
Characterization of Nitrogen Discharge from Extensive Sedum Green Roofs with Multiple Amending Designs and Materials
Publisher: American Society of Civil Engineers
Abstract: Green roofs are effective stormwater control measures for mitigating urban hydrology; however, their potential to manage nutrient discharges has not been consistently documented. Thirty-two pilot scale newly constructed ...
Curve Number and Runoff Coefficients for Extensive Living Roofs
Publisher: American Society of Civil Engineers
Abstract: Living roofs are a green infrastructure (GI)/low-impact development (LID) stormwater control measure (SCM) increasingly drawing worldwide attention. Despite substantial performance evidence in the literature, the lack of ...
