Changes in Stormwater Thermal Loads Due to Bioretention Cells
… event, resulting in higher runoff temperatures. Bioretention cells are a common stormwater control practice identified as a possible thermal mitigation practice in urban watersheds harboring cold-water fish species. However, design specifications vary by locality and few studies have explored how …

Factors Affecting Denitrification Potential and the Microbial Ecology of Established Bioretention Cells Across the Eastern Mid-Atlantic Region
… pollutants directly into natural waterways. Bioretention cells (BRCs) are vegetated soil systems designed to intercept stormwater runoff and reduce loads of water and contaminants discharged to surface waters. Nitrogen removal efficiency is highly variable and improvements are constrained by …

Balancing the Water Budget: the effect of plant functional type on infiltration to harvest ratios in stormwater bioretention cells
Stormwater bioretention cells (BRCs) are a variety of green stormwater infrastructure with the potential to restore pre-urban water balance, provided they can be tailored to infiltrate and evapotranspire (i.e., harvest) urban runoff in proportions consistent with pre-urban hydrologic conditions. …

Efficiency of Bioretention Cells for Stormwater Management Water Quantity Control for Low Density Residential Development: A Case Study in the Greater Toronto Area
Bioretention Cells (BRCs) are new features of Stormwater Management (SWM). The primary objective of BRCs is for water quality treatment but their contribution to water quantity control of SWM is not fully understood. A low-density residential subdivision in the Toronto Area was completed in 2017 …

Characterization and Removal Efficiency Comparison of Bioretention Soil Media Mixtures
<p>Bioretention cells have become a commonly used green infrastructure technique to help infiltrate and remove contaminants from stormwater runoff. Bioretention cells are constructed from a layered or heterogeneous soil mixture designed to optimize their ability to infiltrate influent stormwater …

OPEs, What Do We Do? Modeling Emissions, Fate, and Mitigation of Organophosphate Esters in Urban Systems
… Toronto air emissions to receiving waters. Using bioretention cells as an example stormwater management technology, I undertook a scoping review of bioretention research. This review found that uptake by vegetation was a potentially important pathway for the fate of PMOCs, requiring further study. …

Sensitivity of Stormwater Management Solutions to Spatial Scale
… hydrologic effectiveness of implementing bioretention cells at a watershed scale. Event based analyses, 1-year, 2-year, 5-year and 10-year storms of 24-hours were considered, as well as data from October 2005 to March 2010 for a continuous simulation. The runoff volume reductions achieved …

Using Bioretention Retrofits to Achieve the Goals of Virginia's New Stormwater Management Regulations
… channel erosion. This study models different bioretention cell sizes in a developed watershed in Blacksburg, Virginia to determine the "performance" at both the sub-watershed and watershed levels. In addition, models of "optimal" bioretention cells sized to meet the RRM for each sub-watershed …

Impacts of biota on bioretention cell function during establishment in the Midwest
… region-specific effects of biota on function of bioretention cells, a lysimeter study was conducted at Kansas State University to determine how earthworms and native Kansas grasses impact runoff treatment and hydraulic function of a bioretention cell. This study also employed the Comprehensive …

Does it pay to be mature? Assessing the performance of a mature bioretention cell seven years post-construction
Bioretention cells (BRCs) are low-impact development stormwater management structures that integrate water quantity and quality management. Although BRCs have a predicted design life of about 25 years, most current research focuses on performance of cells less than two years old. This project …

A Stormwater Management Model for California Polytechnic State University Campus
… plans to build. Permeable Pavements (PPs) and Bioretention Cells (BRCs) were the LID types examined. The LIDs were evaluated based on peak flow and runoff volume reductions they would achieve. The potential reductions were compared for current conditions and the proposed project if LIDs were …

Sorption and release of dissolved pollutants via bioretention media.
… One such treatment practice is called bioretention, or rain gardens. This thesis discusses the use of bioretention media as a treatment technique for the removal of toxic metals and investigates the release of phosphorus. A review of previous research and the laboratory experiments will …

Effects of Using Clay Nanoparticles as a Soil Amendment to Remove Nitrate from Stormwater
… stormwater prior to discharge downstream. A bioretention cell is used to treat stormwater pollutants such as nitrate, phosphorus, total suspended solids, and metals. Past research has indicated that the removal efficiency of nitrate by bioretention cells greatly varies from a 75% reduction in …

Sustainability analysis of distributed, green stormwater infrastructure
… Rain gardens, permeable pavement, green roofs, bioretention cells, street trees, swales, and grass strips are all examples of GSI. Distributed, green networks can provide additional environmental benefits beyond hydrologic improvements, including economic and social co-benefits. GSI networks …
