Minnesota Stormwater Seminar Series

Defining the footprint of sediment in green stormwater infrastructure

Please join us in person or online on December 14, 2023 at 10am CST for the next Minnesota Stormwater Seminar Series event - "a monthly experience featuring national, state, and local experts on stormwater and green infrastructure. "This seminar series is a partnership between the University of Minnesota's St. Anthony Falls Laboratory [ [link removed] ] and Water Resources Center [ [link removed] ], and the Minnesota Pollution Control Agency [ [link removed] ], and made possible through the Minnesota Stormwater Research and Technology Transfer Program in collaboration with the Minnesota Stormwater Research Council [ [link removed] ].

*Title*: Defining the footprint of sediment in green stormwater infrastructure [ [link removed] ]

*Speaker: *Dr. Virginia Smith, Associate Professor of Civil and Environmental Engineering and a principal investigator in the Villanova Center for Resilient Water Systems, Villanova University

*Panel Discussion to Follow*

*Abstract: *While green stormwater infrastructure (GSI) has been shown to be an effective solution for stormwater management, they are also highly dynamic due to their spatial variability and living nature. This poses new challenges for urban drainage design, maintenance, and system performance through time, particularly for bioinfiltration GSI. Capture of fine sediments at the surface of the GSI can reduce infiltration due to clogging, while erosion of GSI media, associated with high velocity flows, can erode areas and add to the transport of granular material through the GSI. The movement of sediment is also tied to the fate of pollutants within the GSI. The impact of fines and nutrients, and their effect on bioretention performance, depends on flow velocity and the GSI media. Understanding how the erosive capability, media characteristics, and movement of sediment relate to each other within GSI can help inform design and predict maintenance needs associated with erosion and deposition. 

*Date and Time*: Thursday, December 14, 2023, 10a - 12p CST
