EWN Feature

Featured: Natural Infrastructure represents a source of value for a range of human systems, from local communities to military installations. The USACE Engineering With Nature® Initiative is proud to be part of a multi-organization and multi-sector team that is evaluating the use of nature-based solutions to support our national security within the nearly $5 billion investment being made in Tyndall Air Force Base. The potential to produce tangible value for the defense mission, the environment, and human wellbeing is significant.

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.

Call for Project Nominations for the EWN® An Atlas Volume 2 (ends March 13, 2020).

Due to the strong, positive response to the EWN Atlas, we are now actively planning the development of Volume 2 of the Atlas, where we plan to feature >50 new projects illustrating practice around the world. We are pleased to announce that Volume 2 of the EWN Atlas is planned for publication and release in fall 2020.

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)
