Engineering With Nature® (EWN®) Jekyll Island “Sand Motor”

This project will develop and evaluate key design and decision criteria to develop an actionable, innovative, and shovel ready EWN® “sand motor” (feeder beach) project, that passively distributes sediment across a wide section of retreating shoreline. The objective of the sand motor is to reduce erosion, increase coastal habitat, and provide public safety benefits. Project […]

Application of Engineering With Nature® to Enhance Urban Marsh Resiliency, Biodiversity, and Habitat

This project leverages partner collaboration and incorporates the use of EWN® principles to increase climate resiliency and enhance biodiversity and ecological function of the Belle Isle Marsh in Boston MA. The project will provide engineering, design, and permitting guidance and expertise to enhance the existing urban coastal marsh. Lessons learned from this project will be […]

Engineering With Nature® (EWN®) Toolkit Expansion and Tech Transfer

This project will expand the NNBF modeling capabilities of the EWN® Toolkit for integration into various models commonly used by USACE engineers and the modeling community. The Toolkit will be tested to examine the functionality of the tools for a diverse array of NNBF scenarios. Toolkit guidance and resources will be provided to make the […]

Computational Modeling of Manmade Oyster Reefs: Life-cycle, Wave Attenuation, Performance, and Reliability

This project will advance the state of the practice for manmade oyster reefs through the improvement of computational modeling tools that can simulate the complex physical and ecological dynamics of these features. The new modeling tools will help USACE design and evaluate proposed reef projects, quantify their multiple benefits, and anticipate the performance and evolution […]

Engineering With Nature® (EWN®) Beneficial Use of Dredged Material at Woodtick Peninsula for Coastal Wetland Creation and Protection

This project will create additional wetland habitat on and adjacent to the Woodtick Peninsula through the cost-efficient placement of dredged sediment from the nearby Toledo Harbor federal navigation channel. The project will evaluate techniques for placement of dredged material in relatively inaccessible areas and will explore incorporation of natural features to enhance ecological value. Project […]

Guidance for Modeling EWN® Watershed Management Methods using GSSHA

This project creates guidance and training materials on how to apply EWN®  principles in GSSHA as an integral part of a holistic watershed management plan. By demonstrating the techniques and approaches, and providing guidance on how to apply them, this project will enable engineers and planners to develop better watershed management plans that have a […]

Design and Assessment Guidance for Beneficial Vegetation on Riverside Levees

This project will develop best practices guidance for incorporating beneficial vegetation on the riverside slopes of levees instead of traditional rock or grass. The guidance will provide planners and engineers with the information needed to make vegetation on levees a commonplace EWN®  practice in levee design and rehabilitation. Project Contact Joanna Crowe Curran Products Fact […]

Remote Sensing of Back-Bay Establishment Following Sediment Nourishment

This project will refine remote sensing techniques to monitor morphological and ecological trends of beneficial use of dredged material (BUDM) sites over time. Providing USACE with reliable methods to monitor BUDM sites will provide the confidence needed to initiate more BUDM projects, which in turn will help USACE to reach their goal of using 70% […]

Engineering With Nature® (EWN®) Dogtooth Bend Resilience Support

This project will leverage lessons learned from a traditional USACE-led PL 84-99 focused structural mitigations in big river environments and extract recommendations for future nonstructural multi-agency and partner projects in similar geographic, geophysical, and economic contexts. Enhanced social, economic, and environmental benefits associated with nonstructural flood risk reduction measures and floodplain restoration will be documented […]

Coral Reef Integrated Model Toolkit

This project will develop a modeling tool and guidance documents for forecasting long term coral reef dynamics as a Natural and Nature Based Feature (NNBF). The project will help promote the design and implementation of coral reefs as NNBFs and facilitate their successful incorporation into USACE Coastal Storm Risk Management and restoration studies.
