Engineering With Nature An Atlas

October 2018 - This atlas is a collection of 56 projects that illustrate a diverse portfolio of contexts, motivations, and successful outcomes. These projects are presented and considered in this atlas using an Engineering With Nature® lens as a means of revealing the use of nature-based approaches and the range of benefits that can be achieved.

EWN News

Dr. Todd Bridges will testify at the U.S. Senate Committee on Environment and Public Works oversight hearing entitled “The Role of Natural and Nature-Based Features in Water Resources Projects.” After opening remarks, Dr. Bridges will discuss the USACE Engineering With Nature program.
The hearing will be livestreamed and archived here. (external link)

"A Hemimysis-driven novel ecosystem at a modified rubble-mound breakwater: An Engineering With Nature® Demonstration Project." See how this project used a low-cost design modification applied during the repair of rubble-mound breakwater structures to achieve benefits beyond safe navigation. Read More. (Internal link)

LA Times Op-Ed discusses the need to account for the economic value of natural assets and cost of their loss. One example of natural infrastructure investment highlighted is Reefense, a Defense Department effort to build coral and oyster reefs to defend U.S. military installations in coastal areas around the world.

Engineering With Nature

What is Engineering With Nature?

The U.S. Army Corps of Engineers (USACE) Engineering With Nature (EWN) Initiative enables more sustainable delivery of economic, social, and environmental benefits associated with water resources infrastructure. EWN is the intentional alignment of natural and engineering processes to efficiently and sustainably deliver economic, environmental, and social benefits through collaborative processes. EWN is a cross-cutting program of activities resulting from collaborations among multiple Civil Works Research, Development and Technology programs and non-USACE partners.

What is EWN?

Dr. Todd Bridges, the National Lead for the EWN initiative, explains the four major elements to EWN. DOWNLOAD VIDEO (mp4, 240 mb) TRANSCRIPT (PDF)
