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)
