Fluvial Inland Watershed Guidance Through Experimental Watersheds
This project will develop fluvial inland watershed guidance for studying, analyzing, developing, and implementing watershed-based sediment management practices for successful implementation of water resource projects that incorporate the concepts of EWN®. This guidance will benefit the USACE and stream restoration and sediment management community. FluvialGeomorph (FG) Assessment Development of a basin-wide assessment approach focusing on […]
Large Wood Nourishment Pilot Project at Libby Dam for Improved Kootenai River Functionality
This project will create a permanent large wood nourishment management program at Libby Dam, and provide a template for initiating similar programs in other locations or by other USACE Districts and agencies. The project will demonstrate that natural, process-based approaches can result in more cost-effective solutions compared to more traditional hard engineering approaches.
Developing Streamlined Regional Design and Permitting for Bank Stabilization Projects Incorporating EWN® Principles
This project will create regionalized guidance and tools for landowners to incorporate EWN® methods in riverbank stabilization project in the Missouri Ozarks. The project will also establish a streamlined permit process with all three USACE Districts that regulate activities in the Missouri Ozarks. Finally, the project will hold a training session to educate local landowners […]
Wood Revetment Design Calculator for HEC-RAS
This project will create a wood revetment design tool that will be integrated into HEC-RAS to better assess Natural and Nature Based Features (NNBF) in river engineering and stream restoration designs. The tool will provide engineers with a consistent and reliable process for assessing the stability of wood revetment structures, which will make the review […]
Quantifying the Efficacy of Floating Vegetated Canopies for Shoreline Protection
This project will assess the efficacy of using vegetated floating canopies for shoreline protection. Vegetated floating canopies are a novel Nature Based Solution (NBS) that can dissipate and redirect wave energy before it reaches the coastline. This project will use state-of-the-art observation systems to measure how much wave energy is eliminated by vegetated floating canopies […]
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. Stakeholder […]
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.
