Thin-layer sediment placement (TLP) is a promising management tool for enhancing tidal marsh resilience to rising seas.

This five-minute video shows the January 5, 2023 flooding on North San Pedro Road in China Camp State Park, San Rafael California during an atmospheric river event. The road also floods during winter king tides that raise water levels in San Francisco Bay.

Thin-layer placement (TLP) is an emergent climate adaptation strategy that mimics natural deposition processes in tidal marshes by adding a small amount of sediment on top of marsh in order to maintain elevation relative to sea level rise.

This advisory committee charter, developed for a National Estuarine Research Reserve project to evaluate a thin-layer placement as a strategy for marsh resilience, offers an example for engaging diverse end users in collaborative research.

This story map and K-12 activity invites students to explore coastal marsh vulnerability to sea level rise and a collaborative experiment to enhance marsh resilience at the Chesapeake Bay National Estuarine Research Reserve in Virginia.

This document provides guidance on the use of thin-layer sediment placement (TLP) as a tool for tidal marsh resilience in the face of sea-level rise.
