EWN Research Featured in DredgeWire: Reassessing 40-Year-Old Beneficial Use Projects

Recent completed research conducted by EWN researchers was featured in the online publication, DredgeWire. The article, titled “Scientists Reassess 40-year-old Dredged Sediment Beneficial Use Projects,” explores the long-term impact and effectiveness of pioneering projects and their alignment with the Engineering With Nature (EWN) initiative.

The article highlights the groundbreaking work led by Mary Landin and her team, who designed and implemented habitat improvement projects using dredged sediment between 1974 and 1978. Their projects, intended to mimic local habitats, have served as a foundation for EWN principles. Over the past decades, the sites have not only thrived but have also exceeded expectations.

Recently, Jacob F. Berkowitz, Ph.D., and his team from ERDC revisited these historic projects to assess multidecadal changes in soils, bird life, and plant communities. The research aimed to identify features aligning with the present-day EWN initiative and considered ecological functions, economic considerations, social implications, and other factors referred to as “ecological goods and services.”
