The EWN Atlas series showcase Engineering With Nature principles and practices in action through illustrations and descriptions of constructed projects around the world.

The EWN initiative continually seeks opportunities to provide the public with examples of water resources infrastructure that incorporates innovative designs and measures that are consistent with EWN principles. This page highlights many of the EWN designs that have been identified for a variety of different USACE activities.

EWN Proving Grounds are USACE districts and divisions committed to the broad integration of EWN principles and practices into all business lines in the form of constructed projects. Proving grounds are places where innovative ideas are tested on the ground, throughout USACE missions. They document processes, project milestones, and lessons learned in the implementation of EWN measures so others can learn from their experience.

Listen in as collaborators from local, national and international agencies, private and not-for-profit organizations, and academia discuss ideas and applications of nature-based solutions.
