About the Guidelines
The International Guidelines on NNBF for Flood Risk Management provide practitioners with the best available information concerning the conceptualization, planning, design, engineering, construction, and maintenance of NNBF to support resilience and flood risk reduction for coastlines, bays, and estuaries, as well as river and freshwater systems.
An International Celebration
The virtual launch event was held Thursday, 16 September to collectively celebrate the monumental accomplishment and availability of the International Guidelines on NNBF for Flood Risk Management. The event was live-streamed on YouTube with over 700 live viewers. The program included remarks by Dr. Todd Bridges, messages from guest speakers at partnering organizations around the world, and a panel discussion with individuals who helped author the guidelines.

Please give us feedback on the NNBF Guidelines! We’d like to hear what readers, practitioners, policymakers, and others think about the guidelines, including ways they could be improved in a future update. Let us know!
Exploring the Guidelines
The NNBF Guidelines include 20 chapters organized into three sections: overarching themes, coastal features, and fluvial features. Under each chapter icon, you can view an introductory presentation by a chapter author and explore individual chapters online.

Questions and Anwers
Q: How is the information in the Guidelines organized?
A: The Guidelines are organized so that readers can begin where their interests lie; there was no expectation that someone would start on page one and read each chapter in order until the end. Given the conceptual connections and relationships among the topics covered in the chapters, the chapters were developed in a collaborative environment where there was communication and engagement across chapter teams. Each chapter begins with a list of its key, high-level messages, includes references to other chapters and uses icons and case studies to draw attention to key topics covered elsewhere in the Guidelines. Additionally, there is a shorter Overview publication with the same design and use of icons to introduce each of the chapters in 3-5 pages by highlighting key messages.
Q: When did the team begin developing this document?
A: The process of developing these Guidelines began in 2016 with the first in-person meeting of the project at the US Army’s Engineer Research and Development Center (ERDC) in Vicksburg, Mississippi.
Q: Will the Guidelines be updated in the future?
A: Yes. The international community that jointly developed the Guidelines is resolved to update them, as necessary, as technical work, experience, publications, and applications of NNBF continue to grow.
Creating the NNBF Guidelines
These Guidelines are the product of a large-scale collaboration that included 5 years of working-level meetings and knowledge-sharing involving key practice leaders from around the world.
The project was initiated and led by the US Army Corps of Engineers (USACE) as a part of its Engineering With Nature® (EWN) Initiative. The USACE, the Rijkswaterstaat in The Netherlands, and the Environment Agency in the United Kingdom were the three primary government institutions that organized and led the effort. Many other organizations also provided critical leadership and participation, including the National Oceanic and Atmospheric Administration, World Bank, National Institute of Standards and Technology, and The Nature Conservancy.
Over 180 practitioners, researchers, engineers, scientists, and other professionals from 77 public, private, non-government, non-profit, and academic organizations were part of the global team. All were driven by a desire to collect, organize, and learn from the wide range of experience with NNBF around the world.
