Bioretention: Lab, Big Box Store & Watershed-Scale Research Informs Improved Design  Aug 17, 2022 
Professor Ryan Winston (Ohio State University) presentation focused on recent research findings related to bioretention function at multiple scales. Topics included a controlled laboratory scale study where 7 different bioretention media mixes were tested for nutrient leaching over 1 year of simulated rainfall events. We then transitioned to a field scale study performed at a big box store with interesting findings related to urban karst. A watershed-scale green infrastructure project where >400 bioretention systems were retrofitted into a residential neighborhood will be profiled and results shared related to runoff control and treatment. The presentation concluded with practical takeaways for bioretention design that can be gleaned from these studies.
