Saturated riparian buffers (SRBs) have been shown to be effective at reducing nitrate concentrations in drainage water by as much as 100% at relatively low costs compared to other treatment methods. While promising, many questions remain about the mechanics and long-term impact at SRB sites. Current design standards are limited by conservative guidelines due to a lack of research. This presentation will discuss the purpose and function of SRBs, the effectiveness of SRBs to reduce nutrient export, and the design of SRBs. Results of a streambank slope stability analysis at SRB sites and an investigation of optimal buffer width will be included in the discussion.
Improve understanding of the purpose and function of saturated riparian buffers (SRBs).
Examine the performance of SRBs in the reduction of nitrate export from both agricultural and urban drainage.
Explore current design challenges and solutions related to nitrate removal efficiency and streambank stability at SRB sites.
