N-EWN Seminar: The Lower Klamath Project – The World’s Largest Dam Removal and River Restoration Project
Removal of four hydropower dams (Iron Gate, Copco 1, Copco 2, and J.C. Boyle) on the Klamath River in northern California and southern Oregon represents the largest dam removal and river restoration project in the country. The project restores free-flowing conditions and volitional fish passage to more than 400 miles of historic anadromous fish habitat […]
Natural Infrastructure Short Course at State of the Coast 2025
New Orleans, LA – May 23, 2025 — At the 2025 State of the Coast Conference—the premier gathering for coastal stakeholders in Louisiana—the U.S. Army Corps of Engineers’ Engineering With Nature® (EWN®) program delivered a dynamic half-day short course on implementing Natural Infrastructure (NI) in estuarine systems. Bringing together science, design, and engineering, this workshop […]
EWN Natural and Nature-Based Features Playbook for the Arid Southwest
The Arid Southwest NNBF Playbook Workshop, held May 7–8, 2025, in Albuquerque, NM, brought together more than 35 participants from over 20 federal, state, tribal, academic, and non-governmental organizations. Hosted by the U.S. Army Corps of Engineers (USACE) in collaboration with the Engineering With Nature® (EWN®) initiative, the workshop was designed to support the development […]
N-EWN Seminar: Scaling multi-benefit nature-based solutions projects: case study examples from The Nature Conservancy
The Nature Conservancy is a global conservation organization dedicated to conserving the lands and waters on which all life depends. Guided by science, TNC works to scale innovative solutions to the world’s toughest challenges so that nature and people can thrive together. This mission includes extensive efforts to scale natural infrastructure solutions through policy action […]
N-EWN Seminar: Making the Case for Nature-Based Solutions: Ecosystem Services, Benefit-Cost Analyses, and Storytelling
We all rely on services provided by nature, often in ways we don’t fully recognize. Earth Economics identifies and quantifies those benefits to ensure they are included in the decision-making process at all levels, so communities can mitigate risk, increase resilience, and protect their natural capital wealth. Awareness of the co-benefits associated with nature-based solutions […]
Great Lakes Engineering With Nature Playbook Workshops
The Great Lakes Engineering With Nature (EWN) Playbook Workshop, hosted by the ERDC EWN Program and supported by the USACE Chicago District, brought together experts from government, academia, and private industry to discuss coastal resilience strategies. Over two days, participants shared insights on Natural and Nature-Based Features (NNBF) and Multiple Lines of Defense (MLD) to […]
N-EWN Seminar: Leveraging Partnerships for Living Shoreline Implementation at Scale
Healthy, well-vegetated coastlines are resilient coastlines, able to withstand daily pressures and quickly recover from storm events. Unfortunately, many of our coastlines are not healthy and seem to require ever greater measures for stabilization. Traditional stabilization methods reduce or eliminate many of the ecosystem functions of a vegetated shoreline. Living shorelines are a more ecological […]
N-EWN Seminar: Natural and Nature Based Features (NNBF) for Inland Fluvial Restoration
Engineering With Nature (EWN®) and Natural and Nature-Based Features (NNBF) is a principal component to the U.S. Army Corps of Engineers (USACE) inland fluvial watershed, Flood Risk Management (FRM), Regional Sediment Management (RSM), and Ecosystem Restoration portfolio of programs. In a memo dated April 2024, the USACE Headquarters required all future USACE water resource projects […]
N-EWN Seminar: Ecology and Engineering of Native Plant-Soil Interactions and Riparian Structures
Current engineering practices and regulations for vegetation on levees primarily use non-native, annual or perennial turf grasses. These plants typically have thin, fibrous, shallow roots, require regular labor-intensive mowing, and provide little ecological value. Native vegetation on levees, stream banks, and riparian zones benefits erosion control, pollution mitigation, and habitat protection. Rivercane (a native grass) […]
N-EWN Seminar: The Evolution of a Resilient Coastal Community: Over 20 Years of Beaches, Back Bays, Rivers and Stormwater in Norfolk, Virginia
Since 2003, the City of Norfolk in Virginia has been investigating coastal/estuarine/river erosion issues, compound urban coastal flooding issues, developing long-range resilience plans, and constructing infrastructure projects to improve its diverse communities’ resilience to coastal flooding. Efforts have included wave and water level data collection, coastal shoreline and watershed modeling studies and plan developments, and […]
