Systems Approach to Geomorphic Engineering (SAGE)

The SAGE program increases agency knowledge, skills, and technical abilities to advance use of nature-based solutions (NBS) and green and gray hybrid alternative measures in water resources studies and projects. SAGE focuses on identifying current and future research and policy needs to better adapt and use natural systems to protect against a range of current climate risks and predicted future conditions.

SAGE brings together experts and practitioners from federal and state government, national and international organizations, academia, and the private sector to:

• Promote the integration of green and gray solutions for coastal resilience.
• Encourage regional, landscape-scale planning.
• Implement actions associated with advancing policies that incentivize the use of natural and nature-based solutions.
• Improve communication, coordination, and collaboration across jurisdictions.
• Connect coastal practitioners and existing groups working on natural infrastructure at all levels.

Improving resilience for both people and nature at the landscape scale requires a comprehensive evaluation of a full spectrum of NBS and green and gray hybrid measures, as informed by natural processes. SAGE accounts for economic, environmental, social, and cultural considerations at a regional systems scale, while also preserving and enhancing natural inland and coastal features when possible.

Natural and Structural Measures for Shoreline Stabilization Brochure

USACE and NOAA collaboratively developed an informative brochure that provides an overview of different types of shoreline solutions. This document is a great handout to help people learn about the spectrum of natural and nature-based features.

Ecosystem Governance, Restoration, and Equity Tool (EGRET)

SAGE is developing EGRET, a geospatial decision-support tool designed for USACE coastal planners to identify optimal locations for natural infrastructure development in coastal communities. The tool incorporates information on physical hazards, critical natural resources, and social vulnerability to identify areas that are exposed and vulnerable to a range of coastal hazards. EGRET is intended to help prioritize underrepresented communities in USACE planning processes.
