Analytical Equations for Estimating the Total Runoff Reduction Efficiency of Infiltration Trenches
(American Society of Civil Engineers, 2016)The total runoff reduction efficiency of infiltration trenches can be used as the primary indicator of their stormwater management performance. In this technical note, analytical equations are derived for estimating the ... -
Divergent Vegetation Growth Patterns Relative to Bioinfiltration Unit Size and Plant Placement
(American Society of Civil Engineers, 2015)In 2009, the U.S. EPA constructed six experimental bioinfiltration units (BUs) at the Edison Environmental Center in Edison, New Jersey. They were designed as two sets of three BUs with drainage area to surface area ratios of -
Modeling Soil Matrix Hydraulic Properties for Variably-Saturated Hydrologic Analysis
(American Society of Civil Engineers, 2016)This article presents a method to estimate soil matrix hydraulic properties to be used for variably-saturated hydrologic analysis, such as rainfall/runoff and stormwater management analyses, among others. The methods are ... -
Vegetation and Media Characteristics of an Effective Bioretention Cell
(American Society of Civil Engineers, 2016)A seven-year-old bioretention cell in Silver Spring, Maryland was surveyed for vegetation and media characteristics 11 months after last maintenance. Volunteer plants constituted more than half of the cell vegetation. -
Evaluating the Accuracy of Common Runoff Estimation Methods for New Impervious Hot-Mix Asphalt
(American Society of Civil Engineers, 2016)Accurately predicting runoff volume from impervious surfaces for water quality design events is an important step to meet water quality and infiltration design targets for green infrastructure stormwater control measures. ... -
Effective Saturated Hydraulic Conductivity of an Infiltration-Based Stormwater Control Measure
(American Society of Civil Engineers, 2015)Infiltration rates into field soils have a large variability, and a statistical value that represents the overall infiltration in a site is needed. The Green-Ampt equation was used to develop a one-dimensional, multisoil ... -
Removal of Dissolved Copper and Zinc from Highway Runoff via Adsorption
(American Society of Civil Engineers, 2016)Dissolved copper and zinc are commonly observed in highway runoff at concentrations that have been shown to exert toxic effects on aquatic microbiota and macrobiota. Dissolved copper in particular has been shown to disrupt ... -
Enhanced Denitrification in Bioretention Using Woodchips as an Organic Carbon Source
(American Society of Civil Engineers, 2015)Bioretention systems fundamentally lack the ability to effectively reduce total nitrogen concentrations from urban stormwater. Column tests were conducted to simulate a bioretention anoxic zone and evaluate the effects of ... -
Rainwater Collection and Management from Roofs at the Edison Environmental Center
(American Society of Civil Engineers, 2015)In the past, the U.S. Environmental Protection Agency Edison Environmental Center, a 80.9-ha (200-acre) federal-run facility, directed all rainwater from roofed areas to the existing storm water conveyance system. Over the ... -
Hydrologic Performance of a Transitioned Infiltration Basin Managing Highway Runoff
(American Society of Civil Engineers, 2015)Infiltration basins are widely used stormwater control measures (SCMs) for urban stormwater runoff management. However, these SCMs can experience progressive failure to hydrologically perform as originally designed ... -
Assessing the Effects of Bioretention’s Engineered Media Composition and Compaction on Hydraulic Conductivity and Water Holding Capacity
(American Society of Civil Engineers, 2015)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 ...
