Sediment budgets, transport, and depositional trends in a large tidal delta Sediment budgets, transport, and depositional trends in a large tidal delta
The Sacramento-San Joaquin Delta is the largest delta on the west coast of the United States. It is formed where the confluence of California’s two largest rivers (the Sacramento and San Joaquin) meet the ocean tides and has a significant physical gradient from fluvial to tidal. It is a semidiurnal system (two high and two low tides per day). Today, the Delta is one of the most...

Summary of suspended-sediment concentration data, San Francisco Bay, California, water year 2010 Summary of suspended-sediment concentration data, San Francisco Bay, California, water year 2010
Suspended-sediment concentration data were collected by the U.S. Geological Survey in San Francisco Bay during water year 2010 (October 1, 2009–September 30, 2010). Turbidity sensors and water samples were used to monitor suspended-sediment concentration at two sites in Suisun Bay, one site in San Pablo Bay, three sites in Central San Francisco Bay, and one site in South San Francisco...

A step decrease in sediment concentration in a highly modified tidal river delta following the 1983 El Niño floods A step decrease in sediment concentration in a highly modified tidal river delta following the 1983 El Niño floods
Anthropogenic activities in watersheds can have profound effects on sediment transport through river systems to estuaries. Disturbance in a watershed combined with alterations to the hydro-climatologic regime may result in changes to the sediment flux, and exacerbate the impacts of extreme events (such as large-magnitude floods) on sediment transport. In the San Francisco Estuary...

Suspended-sediment flux and retention in a backwater tidal slough complex near the landward boundary of an estuary Suspended-sediment flux and retention in a backwater tidal slough complex near the landward boundary of an estuary
Backwater tidal sloughs are commonly found at the landward boundary of estuaries. The Cache Slough complex is a backwater tidal region within the Upper Sacramento–San Joaquin Delta that includes two features that are relevant for resource managers: (1) relatively high abundance of the endangered fish, delta smelt (Hypomesus transpacificus), which prefers turbid water and (2) a recently...

Implications for future survival of delta smelt from four climate change scenarios for the Sacramento–San Joaquin Delta, California Implications for future survival of delta smelt from four climate change scenarios for the Sacramento–San Joaquin Delta, California
Changes in the position of the low salinity zone, a habitat suitability index, turbidity, and water temperature modeled from four 100-year scenarios of climate change were evaluated for possible effects on delta smelt Hypomesus transpacificus, which is endemic to the Sacramento–San Joaquin Delta. The persistence of delta smelt in much of its current habitat into the next century appears...
