Water depth, turbidity, and current velocity time-series data were collected in Liberty Island Conservation Bank (WVA) in 2017. The turbidity sensors were not calibrated to suspended-sediment concentration at this location. Typically, each zip folder for a deployment period contains two data files from a velocimeter and one data file from a CTD, each of which include data from an optical backscatter sensor. --------- Data were collected from several sites in Little Holland Tract (LHT) and Liberty Island (LI), including the Liberty Island Conservation Bank (LICB), from 2015 to 2017. Table 1 (below) lists the deployment name (DLXXX) and dates for each sampling station location. Station names starting with ‘H’ are...
Water depth, turbidity, and current velocity time-series data were collected in Liberty Island from 2015 to 2017. Depth (from pressure) and velocity were measured in high-frequency (8 Hz) bursts. Burst means represent tidal stage and currents, and burst data can be used to determine wave height, period, and direction, and wave-orbital velocity. The turbidity sensors were calibrated to suspended-sediment concentration measured in water samples collected on site. The calibration and fit parameters for all of the turbidity sensors used in the study are tabulated and provided with the data. Data were sequentially added to this data release as they were collected and post-processed. Typically, each zip folder...
This Model Archive Summary (MAS) describes the development of a turbidity derived suspended-sediment concentration (SSC) time-series computation model. The MAS includes all the methods and techniques used to develop the model for USGS stations 11455420 Sacramento River at Rio Vista, Ca. The time-series suspended-sediment concentration data are representative of the cross section and are adequate to compute suspended-sediment flux, to help managers and others to track the movement of sediment in the Sacramento-San-Joaquin Delta and to better understand habitat dynamics.

Water depth and turbidity time-series data were collected in Little Holland Tract (LHT) from 2015 to 2017. Depth (from pressure) was measured in high-frequency (6 or 8 Hz) bursts. Burst means represent tidal stage, and burst data can be used to determine wave height and period. The turbidity sensors were calibrated to suspended-sediment concentration measured in water samples collected on site. The calibration and fit parameters for all of the turbidity sensors used in the study are tabulated and provided with the data.

These data present suspended particle size distributions collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at three locations in the Sacramento-San Joaquin Delta. Data were collected in Lindsey Slough on April 4 and April 18, 2017, and near the mouth of the Mokelumne River and in Middle River on March 14, 2018 by deploying a Sequoia Scientific Laser In-situ Scattering and Transmissometry instrument (LISST 100x) from a small vessel during the deployment of the hydrographic time series data instruments. At each site, data were collected 1 to 2 times, generally near the water surface, at mid depth, and near the sediment bed. These data were collected as part of a study on the...
These profiles of suspended-sediment concentration were collected and compiled to characterize suspended sediment in the Colorado River during both average flow conditions and during a controlled flood that occurred in March 2008. The objectives of the study were to measure changes in suspended sediment that occurred during changes in discharge associated with the controlled flood. These data were collected between March 4 and March 10, 2008 in the center of the channel 44.64 river miles downstream from Lees Ferry, Arizona on the Colorado River within Grand Canyon National Park. The sampling location was within a 1-mile study reach beginning 0.14 miles upstream from the sampling location. These data were collected...
Turbidity was continuously monitored at the USGS streamgage Nooksack River at Ferndale (12213100) from October 29, 2011 to September 30, 2017. A DTS-12 turbidity sensor (Forest Technology Systems) at the streamgage measured turbidity at 15-minute intervals. Suspended-sediment samples were collected at the streamgage over a range of discharge and turbidity conditions. Regression equations were developed to estimate the suspended-sediment concentration (SSC) and the concentration of fine suspended-sediment (fSSC; <0.0625 mm) using turbidity as an explanatory variable. A 15-minute time series of SSC, fSSC, and the uncertainty of individual estimates (prediction intervals with 90 percent confidence) was computed and...

During water years 2016–2020, the U.S. Geological Survey, in cooperation with the Illinois Environmental Protection Agency, operated continuous monitoring stations on eight of the major rivers in Illinois to better quantify nutrient and sediment loadings from the State of Illinois to the Mississippi River. This data release presents estimates of daily nitrate, suspended sediment, and phosphorus concentrations and uncertainty from that period. The concentration estimates are based on a combination of discrete sampling data and surrogate regression (imputation). The data release comprises a single csv file containing daily timeseries of concentration and uncertainty for each monitoring station.

These data present suspended particle size distributions collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center within two embayments of San Francisco Bay. Data were collected at one site in San Pablo Bay and one site in Grizzly Bay from January through February 2020 by deploying a Sequoia Scientific Laser In-situ Scattering and Transmissometry instrument (LISST 200x) from a small vessel near pre-established USGS instrument moorings. At both sites, data were collected on four dates at three depths, generally near the water surface, at mid depth, and near the sediment bed, for 1-3 minutes at each depth. LISST volume concentrations are most accurate when the optical percent transmission...

Hydrodynamic and sediment transport time-series data, including water depth, velocity, turbidity, conductivity, and temperature, were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center within two embayments of San Francisco Bay. Data were collected in San Pablo Bay and Grizzly Bay from June to August 2019 at seven unique stations. Data files are grouped by area (shallows of San Pablo Bay, channel of San Pablo Bay, and shallows of Grizzly Bay). Each shallow site contained a variety of sensors located on two tripods and one surface mooring, while the channel site consisted of one tripod. Users are advised to assess data quality carefully, and to check metadata for instrument information,...
This data release provides suspended-sediment (concentration and load) and water temperature data for two locations along the Suiattle River (USGS 12187900 and 12188380) and a tributary, Downey Creek (USGS 12187985) in Washington State for partial periods over 2013-2017. Suspended-sediment and water temperature data were collected over two summer seasons from May through September 2016 and 2017 at USGS 12187900. Suspended-sediment and water temperature data were collected that approximately covers the Water Year 2017, extending from October 24, 2016 to November 16, 2017 at USGS 12187985. Suspended-sediment and water temperature data were collected from December 2013 through September 2017 at USGS 12188380. This...

This U.S. Geological Survey (USGS) Data Release provides selected discretely measured water-quality data collected from 27 monitoring sites in Johnson County, Kansas, during January 2015 through June 2016. Water-quality samples were analyzed for nutrients, Escherichia coli bacteria, total suspended solids, suspended-sediment concentration, and chlorophyll as part of a study to assess the water-quality program for total maximum daily loads in Johnson County, Kansas. Samples were analyzed by the Johnson County Environmental Lab, Johnson County, Kansas, USGS National Water Quality Laboratory, Lakewood, Colorado, and USGS Kansas Water Science Center, Lawrence, Kansas.
