Optimal Selection and Placement of Green Infrastructure in Urban Watersheds for PCB Control
(American Society of Civil Engineers, 2019)San Francisco Bay and its watersheds are polluted by legacy polychlorinated biphenyls (PCBs), resulting in the establishment of a total maximum daily load (TDML) that requires a 90% PCB load reduction from municipal ... -
Reliability-Based Approach to Investigating Long-Term Clogging in Green Stormwater Infrastructure
(American Society of Civil Engineers, 2019)Green stormwater infrastructure (GSI) is defined by the integration of natural processes into the built environment to provide important ecosystem services. While GSI has multiple benefits, its hydrologic performance can ... -
Comparing Greenhouse Gas Fluxes from Passive Urban Stormwater Management to Conventional Wastewater Treatment
(American Society of Civil Engineers, 2019)Green infrastructure (GI) is a popular tool to improve city resilience to climate change and improve water quality. However, because these systems receive pulses of nutrient rich stormwater (SW), they may be contributing ... -
Field Monitoring of Downspout Disconnections to Reduce Runoff Volume and Improve Water Quality along the North Carolina Coast
(American Society of Civil Engineers, 2019)Virtually all land development increases stormwater runoff and disrupts the natural hydrologic cycle. This is a particularly important issue for areas developed prior to the widespread application of stormwater control ... -
Decision Making on the Gray-Green Stormwater Infrastructure Continuum
(American Society of Civil Engineers, 2019)Prioritizing stormwater infrastructure projects is challenging. In addition to regulating runoff and complying with water quality standards, agencies also consider factors such as life cycle costs, environmental impacts, ... -
Site-Scale LID-BMPs Planning and Optimization in Residential Areas
(American Society of Civil Engineers, 2019)Low-impact development best management practices (LID-BMPs) are a representative and effective approach in urban runoff management. In a planning process, it is important to optimally design and place LID-BMPs to maximize ... -
Risk-Based Methodology for Evaluation of Bioinfiltration Design and Performance
(American Society of Civil Engineers, 2019)Green infrastructure practices are being implemented as a sustainable way to manage stormwater. Many communities are implementing green infrastructure practices on their own and in conjunction with gray infrastructure ... -
Design and Construction of Full-Scale Testing Apparatus for Evaluating Performance of Catch Basin Inserts
(American Society of Civil Engineers, 2019)As stormwater runoff flows over impervious surfaces, it suspends and transports various pollutants from their original locations and often conveys them into municipal separate storm sewer systems (MS4s). Most municipalities ... -
Economic and Energy Efficiency of Net-Zero Water Communities: System Dynamics Analysis
(American Society of Civil Engineers, 2018)A net-zero water (NZW) community can be developed by combining various water supply sources, conservation measures, and water reuse approaches over time. A decision support system is required to assess the site-specific ... -
Laboratory Comparison of Field Infiltrometers
(American Society of Civil Engineers, 2018)Three devices for measuring hydraulic conductivity of soil in the field were tested under controlled conditions in the laboratory using three types of media to compare their accuracy and precision: modified Philip-Dunne ... -
Simulated Performance of In-Place Pervious Concrete under Varying Storms, Surface Areas, and Infiltration Rates
(American Society of Civil Engineers, 2018)Computer model simulations were conducted of an existing parking lot with pervious concrete low-impact development (LID) controls using the U.S. EPA Storm Water Management Model (SWMM). For three different types of storms, ... -
Nutrient Removal Rates of Permeable Reactive Concrete
(American Society of Civil Engineers, 2018)Nitrogen and phosphorus contained in stormwater runoff contaminate both surface and groundwaters, causing problems for natural aquatic systems and human health. Pervious concrete specifically designed for pollutant removal, ... -
Evaluating the Effectiveness of Green Roads for Runoff Control
(American Society of Civil Engineers, 2018)Green roads can be incorporated into low-impact development (LID) practices to reduce the risk of flood disasters by collecting rainfall and reusing it as irrigation water for vegetation near the roads. In this study, an ... -
Integrated Urban Water Resources Model to Improve Water Quality Management in Data-Limited Cities with Application to Bogotá, Colombia
(American Society of Civil Engineers, 2018)Cities in developing countries frequently suffer from poor water quality. Thus, the ability to make informed decisions on the current state of urban water quality, as well as on rehabilitating or implementing new infrastructure, ... -
Performance Evaluation of an Alternative Underdrain Material for Stormwater Biofiltration Systems
(American Society of Civil Engineers, 2018)Underdrains are commonly used in biofilter stormwater treatment devices in areas having low soil infiltration rates. These usually are required to reduce the duration of standing water to less than 1–3 days to minimize ... -
SWMM5 Unsaturated Drainage Models for Stormwater Biofiltration with an Internal Water Storage Zone
(American Society of Civil Engineers, 2018)Denitrifying stormwater biofiltration systems are designed to enhance nitrogen removal and operate under saturated and unsaturated conditions; however, unsaturated drainage expressions for these systems are unavailable for ... -
Phosphate Retention in a Constructed Stormwater Wetland with Low Total Suspended Solids Concentrations
(American Society of Civil Engineers, 2018)Although constructed stormwater wetlands (CSWs) have been shown to treat stormwater runoff, the mechanisms controlling these water-quality improvements need further study. This research explores the fate of phosphate through ... -
Evaluation of Continuous Monitoring as a Tool for Municipal Stormwater Management Programs
(American Society of Civil Engineers, 2018)The purpose of this study is to evaluate the uncertainty attributable to inadequate temporal sampling of stormwater discharge and water quality, and understand its implications for meeting monitoring objectives relevant ... -
Hydrologic Modeling and Capital Cost Analysis of Low-Impact Development1
(American Society of Civil Engineers, 2018)Urban development substantially increases the rate and volume of stormwater runoff. Conventional stormwater management focuses on peak rate control while overlooking the increased volume of urban runoff. Low impact development ... -
