Progress and Hope at the UGA and ERDC In-Person Workshop
Last week, we had our first in-person meeting for the Network for Engineering With Nature UGA-ERDC crew since COVID-19 shut down travel in 2019. Throughout our two days in Athens, Georgia, we heard from each research team, learned about how their work has evolved over time, and brainstormed about how we can continue to accelerate…

June 2022 Knowledge Series: Economic Valuation of Nature-Based Infrastructure
Ben Blachly, Susana Ferreira, Yukiko Hashida, Grace Anne Ingham, Craig E Landry & Anna Perry The common method used to calculate Benefit-cost analysis does not incorporate the often-times greater long-term benefits of natural infrastructure (NI) over conventional approaches, putting the selection of NI at a disadvantage. Several groups are moving toward an ecosystem services approach to identifying benefits that people obtain…

May 2022 Knowledge Series: Toolkit for ERDC’s Coastal Storm (CSTORM) Modeling System
Amanda Tritinger, USACE & Matthew Bilskie, UGA Currently, incorporating EWN-based flood protection and restoration designs into storm surge and wave numerical modeling systems is a time-consuming and laborious process. Leveraging codes from the developed Coastal STORM (CSTORM) model framework, this research develops an EWN CSTORM toolkit that can be implemented to streamline the inclusion of EWN…

April 2022 Knowledge Series: Restoring the Nisqually River
Daniel Krenz, USACE In 2009, the tidal waters of Puget Sound breached the Brown Farm Dike in efforts to restore the Nisqually Delta. This was the culmination of the largest tidal marsh restoration project in the Pacific Northwest. Daniel Krenz, regulatory section chief and project manager with the USACE Seattle District, discusses the history of…

February 2022 Knowledge Series: Monitoring and Adaptive Management in EWN Projects
Safra Altman, USACE Technically sound, efficient and applicable methods are needed to track natural infrastructure performance over time, develop the evidence base for future designs, ensure compliance with policy, and inform project operations and adaptive management. Dr. Safra Altman discusses a holistic monitoring framework for natural infrastructure, the specific considerations for monitoring before and after…

January 2022 Knowledge Series: Quantifying the Multi-Scale Benefits of Natural and Nature-Based Features
Todd M. Swannack, USACE Natural and nature-based features (NNBF) provide a diverse suite of benefits to society, including flood risk reduction, socio-economic development, water and food security, and habitat. Unlike traditional structural measures, benefits of NNBF accrue over time due to the inherent dynamism of natural features. Capturing and quantifying the benefits requires a multi-scale…

September 2021 Knowledge Series: Characterizing USACE EWN Projects
Brook Herman, USACE This presentation reviews the current EWN ProMap and how proposed changes to the online database will increase our ability to track and assess how well projects are contributing to multiple environmental, economic, and social benefits. Proposed changes to the data entry field include information on what assessment methods were used to calculate…

Network for Engineering With Nature (N-EWN) Collaboration
The U.S. Army Corps of Engineers (USACE) and University of Georgia (UGA) recently announced a partnership that connects the interdisciplinary expertise of UGA’s Institute for Resilient Infrastructure Systems (IRIS), with the vast on-the-ground experience of USACE’s Engineering With Nature® (EWN®) Initiative to form the Network for Engineering With Nature (N-EWN).
