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…

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…
