Water depth and depth-averaged water velocity in the lower San Joaquin River, California, collected generally near Greyson Bridge, the Old Fishermen's Club, and Sturgeon Bend. These data were collected using a SonTek M9 Acoustic Doppler Current Profiler (ADCP) May 10-11, 2012, and May 24-25, 2012.

Introduction In 2012, Hurricane Sandy created an open breach in the barrier island system along the south shore of Long Island, N.Y. This breach formed at a location known as Old Inlet and migrated rapidly westward over the winter storm season following Hurricane Sandy. In response, the National Park Service sought assistance from the USGS New York Water Science Center to help evaluate the hydrodynamics and geomorphology of the breach. The evaluation is centered on measurement of water velocities and depths within the breach, and collection of water levels with the Great South Bay adjacent to the breach. This project is part of a larger ongoing study prepared in coordination with the National Park Service...

Field observations of water and suspended-sediment fluxes at the Golden Gate were made over one ebb tide and one flood tide on three occasions: 1) 21-22 March 2016, following a large storm event that triggered the first flow into Yolo Bypass flood control structure since 2011; 2) 23 June of 2016, during a period of low freshwater inflow and 3) 27-28 February 2017, following several large storms of the wettest winter in northern California in recorded history. On each occasion, flux of water and suspended sediment were estimated using data from a boat-mounted acoustic Doppler current profiler. This instrument provided high-resolution velocity and acoustic backscatter (ABS) data at a cross-section (“transect”) near...

The Bathymetry surface was created by plotting depths of all data points collected relative to North American Vertical Datum of 1988 (NAVD 88), which was converted using the Vertical Datum Transformation tool created by the National Oceanic and Atmospheric Administration's (NOAA) National Geodetic Survey, Office of Coast Survey, and Center for Operation Oceanographic Products and Services. The elevation of the bathymetric raster surface was interpolated between these points in a GIS using a spline interpolator. A total of 432 points were used for interpolation. The points were used as the input to create a polygon feature class. The Spline tool was applied using the points and polygon to interpolate the bathymetric...

Field measurements of water depth were acquired from a reach of the upper Sacramento River in northern California, September 12-14, 2017, to support research on salmon habitat and geomorphic change along the Sacramento River and, more broadly, remote sensing of rivers. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the water's edge and bed elevations within the channel; depths were calculated by subtracting bed elevations from the nearest water surface elevation. For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor...

Water depth and depth-averaged velocity in the lower San Joaquin River, California. These data were collected using a SonTek M9 Acoustic Doppler Current Profiler (ADCP) 2014.

Field measurements of water depth were acquired from a reach of the Snake River in Grand Teton National Park, WY, August 19-24, 2015, to support research on channel change along the Snake River and, more broadly, remote sensing of rivers. The depth measurements included in this data release were obtained by wading the shallow channel margins and measuring the water depth directly on a top-setting wading rod used to collect flow velocity data with an acoustic Doppler velocimeter (ADV). For the deeper areas representing most of the channel, depths were recorded along a series of cross-sections by a SonTek RiverSurveyor M9 acoustic Doppler current profiler (ADCP) deployed from a kayak with the vertical beam of the...

Field measurements of flow depth and velocity and river discharge were collected from two cross-sections on the Blue River in Colorado using an acoustic Doppler current profiler (ADCP). These data were used to assess the accuracy of surface flow velocities inferred from thermal image time series, acquired from an unmanned aircraft system (UAS), via particle image velocimetry (PIV). These data sets were collected to support research focused on developing innovative methods for non-contact measurement of river discharge based on various forms of remotely sensed data. The ADCP data were collected with a SonTek RiverSurveyor S5 mounted on a hydroboard towed behind an inflatable kayak. Four passes were made across...

To suport an investigation of the feasibility of measuring river discharge using remotely sensed data acquired from an unmanned aircraft system (UAS), several types of remotely sensed data and field measurements were collected from two cross-sections on the Blue River in Colorado, just upstream of its confluence with the upper Colorado River, on October 18, 2018. This parent data release includes links to child pages for the following data sets: 1) Lidar data used for mapping channel bathymetry (depth), acquired with a novel instrument that was developed by ASTRALiTe to distinguish between returns from the water surface and riverbed based on the polarization of laser pulses. 2) Thermal image time series used to...

Geo-referenced two dimensional velocity profiles collected at discrete cross-sections over an approximately 2km stretch of the Sacramento River. These data were collected over a range of river conditions (stage and discharge) on eight separate dates in February and March of 2016 and May of 2017. Data are available as .csv files contained in the attached .zip file.

Three streamflow measurements are used to demonstrate the use of equations developed in Mueller (in review). All three measurements are from various locations on the Mississippi River. These data were not collected for the purpose of this paper but provide practical examples of the effect of heading errors. The use of data from the Mississippi River allows the collection of 500 or more ensembles in each transect which reduce the overall effect of random errors that could complicate the identification of effects due to heading errors. In addition, by using wide cross sections, the effect of GPS errors due to vegetation near the boundaries of the river are minimized. All measurements were collected with WinRiver II...

Water depth and depth-averaged velocity in the lower San Joaquin River, California. These data were collected using a RD Instruments Acoustic Doppler Current Profiler (ADCP) April 2013.
The estimation of mass concentration of suspended solids is one of the properties needed to understand the characteristics of sediment transport in bays and estuaries. However, useful measurements or estimates of this property are often problematic when employing the usual methods of determination from collected water samples or optical sensors. Analysis of water samples tends to undersample the highly variable character of suspended solids, and optical sensors often become useless from biological fouling in highly productive regions. Acoustic sensors, such as acoustic Doppler current profilers that are now routinely used to measure water velocity, have been shown to hold promise as a means of quantitatively estimating...
