Description:
The Ground Water and Ecosystem Restoration Division (GWERD) of the USEPA investigates best management practices (BMP’s) and restoration techniques in aquatic ecosystems throughout the United States. Research on a) river restoration b) riparian buffer zones c) macrophytes, and d) floodplain / wetland management is underway at GWERD in order to develop methods to enhance ecosystem services such as nutrient processing, sediment control, temperature moderation, and biodiversity. An area of research emphasis at GWERD is how geomorphic structures and restoration techniques might be employed to mitigate nitrogen pollution by promoting naturally occurring microbial processes, like denitrification that permanently remove nitrogen pollution. In floodplain systems, like the Willamette River, hydrology and nutrient dynamics are complex and interrelated. Cutting edge tools are being used and developed to understand how water moves through the floodplain and how nutrients are transformed within floodplains. Here, we describe some early research findings from our collaboration with the McKenzie River Trust. This work is intended to assist resource managers understand their systems and implement management strategies across the country.
