EWN researchers, Chris Haring and Autumn Murray, from ERDC Coastal and Hydraulics Laboratory (CHL) and the USACE Louisville District (LRL) engaged in site visits during the week of November 13, 2023. Their focus: evaluating existing shoreline protection methods, discussing adaptive management, and planning new projects. This initiative aims to explore alternative designs for shoreline protection, offering a spectrum of benefits from sediment reduction to aquatic habitat enhancement.
Shoreline Degradation
Shoreline erosion within reservoirs poses significant concerns affecting water quality, recreational activities, and fisheries. Nolan River Lake faces similar challenges, compounded by siltation impacting storage capacity. Dynamic shoreline conditions hinder the establishment of vital vegetation, exacerbating erosion concerns.
Enhancing Shoreline Stability
Figures below depict the longitudinal stone toe protection (LPSTP) and the natural revegetation and bank stabilization post-construction at the Point project in 2017. The LPSTP, for instance, is projected to naturally fill unplanted areas and encourage revegetation.
Research and Development Ahead
ERDC and LRL delve deeper, exploring modifications to existing projects to amplify EWN® applications and their environmental impact. Monitoring ongoing reef ball applications and integrated woody materials will drive adaptive management for both protection and habitat advantages.
The comprehensive documentation and recommendations from these initiatives will steer the development of a strategic EWN® shoreline stabilization planning document, aiming to set new standards and practices in the field.
