Flow and Water Quality Data in the San Francisco Estuary

The San Francisco Bay and Sacramento-San Joaquin Delta form one of the largest estuaries in the United States. Water flow and water quality in the San Francisco Bay-Delta Estuary are important to the economies of both California and the nation. The Bay-Delta system provides water to more than 25 million California residents and vast farmlands, as well as key habitat for birds, fish, and other...

Acoustic doppler current profiler (ADCP) data collection of water flow at Benicia Bridge, 2004

This data release contains acoustic Doppler current profiler (ADCP) data used in generating a model of sediment flux through Carquinez Strait, CA at Benicia Bridge. The ADCP outputs binary data files containing measurement scheme, location, time, velocity, backscatter, boat heading, depth, and other parameters. There are two forms of data provided, one collected from two transects along the wester

Acoustic doppler current profiler (ADCP) transect data at Benicia Bridge and Mallard Island, 2019

Field observations of water and suspended-sediment fluxes were conducted at Benicia Bridge and Mallard Island during the 2019 water year wet season to capture suspended-sediment flux during elevated Sacramento-San Joaquin Delta discharge. Measurements occurred on two occasions: 1) 26th of February 2019 at Benicia Bridge and Mallard Island, following a storm event that increased delta outflow and 2

Erodibility Data from Gust Erosion Chamber Experiments in Grizzly Bay and San Pablo Bay, California, Winter 2020

A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained from San Pablo and Grizzly (within Suisun) Bays in California. A pair of sediment cores were collected from the same approximate locations in each bay five times between January 22nd, 2020 and March 11th, 2020 for a total of 10 experiments and 20 sediment core results. Locations were chosen to capture the b

Erodibility Data from Gust Erosion Chamber Experiments in Grizzly Bay and San Pablo Bay, California, Summer 2019

A Gust erosion chamber was used to apply horizontal shear stress to sediment cores obtained from San Pablo and Grizzly (within Suisun) Bays in California. A pair of sediment cores were collected from the same approximate locations in each bay six times between June 12th, 2019 and August 15th, 2019 for a total of 12 experiments and 24 sediment core results. Locations were chosen to capture the bent

Sand supply to San Francisco Bay from the Sacramento and San Joaquin Rivers of the Central Valley, California

Sediment from the Central Valley via the Sacramento-San Joaquin Delta (Delta) and Suisun Bay is a primary source of sand to San Francisco Bay, California. Sand is mined from San Francisco Bay for commercial purposes, such as for use in concrete for construction. To better understand the supply of sand to Suisun Bay and San Francisco Bay, the U.S. Geological Survey (USGS), in cooperation with the S
