Dr. Robert Walter and Dr. Dorothy Merritts of Franklin & Marshall College will present a webinar on November 13 from 1 to 3 p.m. on their work demonstrating the importance of considering the impact of 18th and 19th century mill dams and legacy sediments on stream restoration in the Eastern U.S.

Past assumptions about sediment distribution in streams and streambank erosion are challenged with serious implications for current water quality and wetland restoration efforts.

The importance of these findings will be seen in a stream that was returned to pre-settlement conditions resulting in growth of 200 year old seed into natural wetlands and greatly improved water quality.

This work has important implications for both water quality improvement and increasing natural wetland acreage. The goal will be to understand the history and stream science and hopefully identify other potential sites to demonstrate these restoration techniques.
