New Engineering Practice Guide Advances Oyster Reefs as Natural Infrastructure

The Engineering With Nature® (EWN®) program is pleased to announce the release of the Engineering Practice Guide for Oyster Reefs: A Natural Infrastructure Approach for Coastal Systems, the second publication in a growing series of Engineering Practice Guides for Natural Infrastructure.

Cover of ERDC Technical Report 26-16, Engineering Practice Guide for Oyster Reefs: A Natural Infrastructure Approach for Coastal Systems, from the Engineering With Nature® Program, dated June 2026. U.S. Army, U.S. Army Corps of Engineers, and ERDC logos appear across the top. The cover features two close-up photographs of oyster clusters and small circular illustrations representing different oyster reef materials and structures. A red vertical sidebar identifies the Engineer Research and Development Center and report number ERDC TR-26-16. The bottom states that the report is approved for public release with unlimited distribution.

Engineering Practice Guide for Oyster Reefs — currently available

The new guide supports engineers, ecologists, and interdisciplinary teams in designing oyster reefs as natural infrastructure. It brings engineering and ecological principles together to help practitioners evaluate site conditions, project objectives, performance, costs, risks, and long-term sustainability.

Well-designed oyster reefs can provide multiple benefits, including attenuating wave energy, influencing sediment transport, stabilizing shorelines, creating habitat, and supporting estuarine productivity. The guide provides a practical framework for considering these functions when developing oyster reef projects for coastal systems.

Building a Library of Engineering Practice

The oyster reefs guide follows the Engineering Practice Guide for Floodplain Benching, the first publication in the series. Together, these guides are building a technical resource for practitioners seeking to incorporate natural infrastructure into water resources projects.

Five additional Engineering Practice Guides are currently in development:

  • Wood-Based Riverbank Stabilization
  • Tidal Flow Reconnection for Wetlands
  • Cobble and Gravel Beach Design
  • Leaky Structures
  • Vegetated Bank Biostabilization

As the collection grows, these guides will provide practitioners with an expanding technical foundation for incorporating natural infrastructure and hybrid approaches into inland and coastal water resources projects.
