Engineered and Environmental Controls of Microbial Denitrification in Established Bioretention Cells
Environmental Science & Technology, 2018Bioretention cells (BRCs) are effective tools for treating urban stormwater, but nitrogen removal by these systems is highly variable. Improvements in nitrogen removal are hampered by a lack of data directly quantifying the abundance or activity of denitrifying microorganisms in BRCs and how they are controlled by original BRC design characteristics ...

Bioretention Cell Design for Full Scale Project in Grove, Oklahoma
2006 Portland, Oregon, July 9-12, 2006, 2006Bioretention cells are gaining popularity as a stormwater best management practice (BMP). This can be largely attributed to the fact that they present a broad range of potential benefits such as decreased runoff, improved water quality through various physical, chemical and biological processes, thermal attenuation, and aesthetics. Used on a variety

Process Modeling of Storm-Water Flow in a Bioretention Cell
Journal of Irrigation and Drainage Engineering, 2011A two-dimensional variable saturated flow model was developed to simulate subsurface flow in bioretention facilities employing the Richards’ equation. Variable hydrologic performances of bioretention are evaluated using the underdrain outflow hydrographs, outflow volumes for 10 storms with various duration and depth, and flow duration curves for 25 ...

Bioretention cell efficacy in cold climates: Part 1 — hydrologic performance
Canadian Journal of Civil Engineering, 2012Bioretention cells are an emerging low impact development technology that address urban stormwater runoff concerns. Field and column experiments were conducted to assess the efficacy of bioretention cells in cold conditions. Field experiments in a prairie environment demonstrated a significant decrease (91.5%) in effluent volumes compared to influent ...

Promoting Successful Urban Watershed Restoration Through Enhanced Bioretention Cell Modelling
2018Urban runoff and stormwater is one of the top ten leading causes of water quality impairment in lakes, estuaries and streams in the United States (USEPA 2009). Over the last decade, bioretention systems have become a leading stormwater control measure (SCM) that contributes to the restoration of urban streams and watersheds. Bioretention cells increase

Changes in Stormwater Thermal Loads Due to Bioretention Cells
2021Cold-water fish species such as trout are a game species of large economic value that are very susceptible to changes in water temperature. Due to warmer runoff temperatures from urban watersheds stream temperatures are increasing, posing a potential impact on the cold-water fish found in these watersheds.

Bioresource Technology
This study investigated the reduction of methane (CH4) and nitrous oxide (N2O) emissions from stormwater bioretention cells through microbial electrolytic cell (MEC), showing the largest reduction of 32.21 % (CH4) at 9.2 μA/m2 of current density and 56.16 % (N2O) at 3.5 μA/m2 of current density, compared with the corresponding in the control (0 μA/m2 ...
