Sediment for Survival fact sheet

The tidal marshes and tidal flats along the San Francisco Bay shoreline depend on sediment delivered by the tides. Healthy sediment supplies are essential for maintaining resilient marshes and tidal flats that can persist into the future and build up as sea level continues to rise. Currently, the sediment supply in the Bay is adequate to meet the sediment needed by tidal marshes and tidal flats. However, as sea level rise accelerates in the coming decades, the sediment needed for these habitats to survive will increase considerably.
