PROJECT HIGHLIGHT:
This project focuses on expanding expertise in dune restoration and implementation approaches to enhance coastal resilience, restore and preserve sandy habitats against sea level rise and other potential changes.
PROJECT SUMMARY:
Planning for adaptation to sea level rise, storm erosion, flooding and other coastal hazards poses difficult challenges, particularly for highly populated urban communities along California’s coast, where southern California’s sandy beaches are particularly vulnerable to sea-level rise. Nature-based approaches can enhance resilience, restore and preserve sandy coastal ecosystems, including beaches and dunes. For urban communities, nature-based projects that restore linked beaches and dunes provide an adaptation strategy to increase the resilience of the coastline to sea level rise, flooding, erosion and storm events, but our understanding of these systems is severely limited.
This project is designed to improve our understanding of existing southern California dune restoration and adaptation projects and evaluate how these experimental projects have persisted and responded to coastal hazards over the last 5-20 years. The fellow completed field surveys at 10 restoration sites across three counties, collecting new standardized data on key metrics (e.g., vegetation cover, geomorphic variables) across a gradient of projects that can be integrated with existing data to develop a framework informing site suitability for future beach and dune restoration projects.
The project has already yielded a journal article in Shore and Beach, focused on one particular restoration project (see https://asbpa.org/publications/shore-and-beach/shore-beach-in-2024-vol-92/evaluating-the-response-of-a-pilot-dune-restoration-project-on-an-urban-beach-to-an-extreme-wave-surge-event/), and a manuscript of the full findings is under preparation. The researcher will share the results with relevant agencies and other organizations to inform coastal management and policy by evaluating trajectories and synthesizing expectations for beach and dune projects in southern California.
