Salt marshes, critical buffers against coastal erosion, rely on a net gain of sediment to maintain their elevation and resilience as sea levels rise. A new study examines how two different sediment delivery routes—wave-battered marsh edges and meandering tidal creeks—combine to shape the future of these vital ecosystems.

A fresh report from SF Estuary Institute and the prospect of major development along the marsh’s borders are putting Suisun back in the news.
