Calendar Event

Stormwater Subsurface Gravel Wetlands in Vermont: Do they meet expectations?

Nov 18, 2020
12:00 pm to 1:00 pm

Andres Torizzo, Principal Hydrologist at Watershed Consulting, will explain ongoing research on the effectiveness of subsurface gravel wetlands on flow attenuation and phosphorus capture, and how chloride impacts performance. The research addresses a timely question, as many Vermont municipalities have focused state stormwater permit applications on use of subsurface gravel wetlands to meet impending phosphorus control requirements, but performance data from field installations is lacking.

This presentation describes work conducted as part of the Stormwater Subsurface Gravel Wetlands in Vermont project, which is funded by Lake Champlain Sea Grant and implemented by Watershed Consulting and partners.

The event will take place on Zoom, and registration is required. After registering, you will receive a confirmation email containing information about joining the webinar.

Please expect approximately 30 minutes of presentation followed by a facilitated, 20-minute Q&A period.
