These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Topographic survey data were collected along planned lines from the river water surface to the top of the bank in the study area. Topographic survey data collection began on May 22 and concluded on June 10, 2014. A real-time kinematic (RTK) GNSS network provided real-time survey grade horizontal and vertical positioning.
These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format, generated from hydrographic and velocimetric surveys of the Mississippi River near structure A6500 on Interstate 70 in St. Louis, Missouri, in 2009 and 2016. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach. Data collection software integrated and stored the depth data from the MBES and the horizontal and vertical position...

The minor clay step features are defined as having a vertical face that is less than or equal to 1.5 meters. The clay step features were qualitately identified using an underwater video monitoring sysyem. The extent and magnitude of the clay steps were mapped using a muliteam bathymetric echosounder system.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The shaded relief raster data was created based on bathymetry obtained in the meander reach collected in about a one month period extending from 6/3/2010 - 6/19/2010. This subset data extends from river kilometer designator 228 upstream to 237. Similar methods used to collect and process the bathymetry are described in Fosness (2013). The shaded relief was created from a surface raster (also referred to as digital elevation model)...
Scouring of streambed material surrounding bridge structures is a leading cause of bridge failure in the United States. Damages resulting from bridge failure oftentimes lead to financial burdens and loss of life. To date, there has been no comprehensive evaluation of the current (2016) effectiveness of the guidance or overall long-term performance of bridge-scour countermeasures provided in the Federal Highway Administration, Hydraulic Engineering Circular No. 23, Bridge Scour and Stream Instability Countermeasures. To that end, the U.S. Geological Survey, in cooperation with the Federal Highway Administration, obtained bathymetric, topographical, and other data at 14 of the surveyed sites across the United States...

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format, generated from hydrographic and velocimetric surveys of the Missouri River near structures A4757/L0568 on Missouri State Highway 291 in Kansas City, Missouri, in 2010, 2011, and 2015. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach.

These data are high-resolution bathymetry (riverbed elevation) and depth-averaged velocities in ASCII format, generated from hydrographic and velocimetric surveys near highway bridge structures over the Missouri and Mississippi Rivers on the periphery of Missouri, for dates ranging from 2008 to 2018. Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel. Data were collected as the vessel traversed the river along planned survey lines distributed throughout the reach. Data collection software integrated and stored the depth data from the MBES and...
The U.S. Department of Agriculture - Forest Service (USDA-FS) has been evaluating hazards and classifications at the dams of four small reservoirs in the Mark Twain National Forest in Missouri. These reservoirs are Crane Lake near Annapolis, Fourche Lake near Briar, McCormack Lake near Greer, and Sterling Hollow Lake near Willow Springs. Conventional topographic surveys were used to provide data needed for as-built information of the earthen dam structure, spillways, and groins at each of the dams. High-resolution terrestrial light detection and ranging (T-LiDAR) data also were collected for the concrete spillway structure at Crane Lake Dam to provide baseline data for potential monitoring and change detection....

Hydrographic data were collected using a high-resolution multibeam echosounder mapping system (MBMS), which consists of a multibeam echosounder (MBES) and an inertial navigation system (INS) mounted on a marine survey vessel.

These geospatial data were collected during the July 11-28, 2016 topographic and hydrographic survey of the Jefferson River at MT-2, near Three Forks, MT.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Hydrographic survey data were collected from May 22 through June 10, 2015, using an acoustic Doppler current profiler (ADCP) coupled with an RTK-GNSS rover. The collected hydrographic data consisted of three elements—riverbed elevations derived from bathymetry, depth-averaged streamflow velocity, and instantaneous discharge measurements. Hydrographic data were collected as the boat moved across the river at planned cross sections...
A bathymetric survey of Gillham Lake, Arkansas, was conducted in late June 2018 by the Lower Mississippi-Gulf Water Science Center of the U.S. Geological Survey (USGS) using methodologies for sonar surveys like those described by Wilson and Richards (2006) and Richards and Huizinga (2018). Data from the bathymetric survey were combined with data from an aerial Light Detection And Ranging (LiDAR) survey conducted in 2016 by the National Resources Conservation Service (U.S. Geological Survey, 2017) to create a digital elevation model (DEM) of the extent of the flood pool of the lake and compute volume (storage capacity) of the lake at 1-foot increments in water surface elevation from 431-559 feet (ft) above the North...

Topographic data were collected at a recreation site on the Fourche La Fave River, about 5 miles upstream from Nimrod, Arkansas, on March 4, 2020, using terrestrial light detection and ranging (T-lidar), Global Navigation Satellite System (GNSS), and conventional surveying techniques (Rydlund and Densmore, 2012). These data are high-resolution topography in laser scan format, collected using a tripod mounted T-lidar at multiple scan setups. Data collection software integrated and stored the range and angular measurements from the T-lidar equipment. Computer software was used to process the raw data, align the various scans in reference to one another, classify the data, and extract the topography data in a useable...
