Sediment Transport
Sediment supply is important to the health of estuarine ecosystems, such as the Sacramento-San Joaquin River Delta and San Francisco Bay (Bay-Delta). Sediment from watersheds is delivered downstream by rivers and streams and is deposited in deltas, mudflats and tidal wetlands. This process can help maintain wetlands and helps protects against coastal erosion and the effects of sea-level rise. Sediment also plays a crucial role in the preservation of habitat for wildlife such as birds and fish.
