Natural Hazards
USGS science is helping to understand the risks natural hazards pose to Bay-Delta communities, infrastructure (such as buildings, bridges, roads, utilities, levees, and waterways), and habitats. Threats to the region include earthquakes, land subsidence, flooding, landslides, wildfires, and climate impacts such as drought and sea-level rise.

Sediment Transport in Coastal Environments
Our research goals are to provide the scientific information, knowledge, and tools required to ensure that decisions about land and resource use, management practices, and future development in the coastal zone and adjacent watersheds can be evaluated with a complete understanding of the probable effects on coastal ecosystems and communities, and a full assessment of their vulnerability to natural...
Sediment transport between estuarine habitats in San Francisco Bay
We investigate mechanisms of sediment transport, resuspension dynamics in shoals, wave evolution in the shallows, wave attenuation in marshes, and transport of sediment between mudflats and marshes. We produce data sets for calibration of and comparison with sediment transport models, including wave parameters, suspended sediment concentration, and sediment flux.
Earthquake Monitoring
Earthquake monitoring in the Delta and more generally in California is a partnership among Federal, State, and university agencies, including USGS.
Fault Characterization
USGS science helps to understand and quantify the risks natural hazards pose to Bay-Delta habitats, communities, and infrastructure.
