This data release includes the data and code used for the paper titled "A framework to facilitate development and testing of image-based river velocimetry algorithms", published in the journal Earth Surface Processes and Landforms. Three *.csv files and five *.m files with MATLAB source code are included below. Each *.csv file contains output from a hydrodynamic model of a reach of the Sacramento River near Glenn, California, with a separate file for each of three different discharges (i.e., streamflow rates): 90, 191, and 255 cubic meters per second. The hydrodynamic model used for this purpose was the Nays2DH solver available within the International River Cooperative Interface (iRIC). Provided below is a link...

We have dated a boulder field in Zepp, VA using cosmogenic Be-10 exposure dating. Three samples taken from boulders at three elevations in the boulder field (804 m asl, 818 m asl, and 831 m asl) were processed at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the file “Zepp_Exposure_Beryllium10_Odom.csv”. This file contains all relevant sample location data, as well as input variables for exposure age calculations. We employed the CRONUS v.3 exposure age calculator (Balco et al., 2008) to estimate exposure ages for these samples and report exposure ages derived using the LSDn time-dependent...

This table contains sediment sample information and results of particle size, elemental composition, and fallout radionuclide analyses. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. First posted - October 18, 2023 (available from author). Revised - March 28, 2024 (version 2.0). This data release has been revised to include data from samples collected in 2023 that were not published in version 1.0.

This data release includes cross section survey data collected during site visits to USGS gaging stations located throughout the Willamette and Delaware River Basins and multispectral images of these locations acquired as close in time as possible to the date of each site visit. In addition, MATLAB source code developed for the Bathymetric Mapping using Gage Records and Image Databases (BaMGRID) framework is also provided. The site visit data were obtained from the Aquarius Time Series database, part of the USGS National Water Information System (NWIS), using the Publish Application Programming Interface (API). More specifically, a custom MATLAB function was used to query the FieldVisitDataByLocationServiceRequest...

This U.S. Geological Survey (USGS) data release contains results from the 2020 and 2021 geomorphic survey of North Fork Eagle Creek, New Mexico. Both geomorphic surveys were conducted by the USGS, in cooperation with the Village of Ruidoso, New Mexico, and are the last set of surveys in a planned series of five annual geomorphic surveys of the stream reach located between the North Fork Eagle Creek near Alto, New Mexico, streamflow-gaging station (USGS site 08387550) and the Eagle Creek below South Fork near Alto, New Mexico, streamflow-gaging station (USGS site 08387600). Specifically, there are two data release files, one each for the 2020 and 2021 surveys, that include the results from 14 cross-section surveys...

In May 2023, the U.S. Geological Survey provided training for bathymetric data acquisition and processing for the Iraq Ministry of Water Resources. The training included multibeam sonar theory, survey planning, data collection and processing, and dissemination. This data release presents the raw survey data, a digital elevation model (DEM), and a thalweg shapefile for three survey areas in the Pacific Northwest, USA (Mores Creek, Idaho; Columbia River, OR; Willamette River, OR). Additionally, metadata describes the processing steps, quality assurance and control, and an overall summary of each dataset. The bathymetry point cloud data were collected at selected study sites in the Pacific Northwest, U.S.A, May 2023...
In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S Geological Survey (USGS) in cooperation with the NCDOT conducted a pre-construction bathymetric survey of the streambed in June 2019 (Whaling and Wagner, 2021) within a one-kilometer reach of the FBR at the bridge construction site. A canoe-based repeat bathymetric survey was collected with a single-beam echosounder approximately 30 months after construction began, with the purpose to monitor geomorphological changes to the streambed and inform the NCDOT of potential impacts...
This data release includes data created, collected, and/or otherwise modified in the process of quantifying a sediment budget for the Smith Creek Watershed near New Market, Virginia, USA. Five raster files are included, namely a modeled index of hydrological connectivity, a raster model of modeled floodplain depositional masses and extent, a rasters of modeled gross and delivered upland erosion, and a hydrologically conditioned Digital Elevation Model (DEM). Two vector shapefiles are also included. The first documents the results from the stepwise linear regression models developed to estimate erosion attributed to streambeds, streambanks, and floodplains along stream reaches throughout the watershed. The second...
This Data Release contains preliminary versions of three related geologic input databases for the Puerto Rico and U.S. Virgin Islands (PRVI) region (62°–70° W and 16°–21° N) of the United States: 1) A fault sections database (“NSHM2025_FaultSections_PRVI_v1’”), which depicts the geometry of faults capable of hosting independent earthquakes, 2) a fault-zone polygon database ("NSHM2025_FaultPolygons_ PRVI_v1"), which depicts the geometry of distributed fault zones capable of hosting repeated large magnitude events but a specific fault source remains unidentified, and 3) An earthquake geology site information database (“NSHM2025_EQGeoDB_ PRVI_v1”), which contains fault slip-rate and earthquake recurrence constraints...

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Cumberland 30 x 60 minute quadrangle in Pennsylvania, West Virginia and Maryland. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2019 and 2023. The data were processed using geographic information systems (GIS) software. The data is projected in WGS 1984. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.

This data release contains foreshore slopes for primarily open-ocean sandy beaches along the west coast of the United States (California, Oregon and Washington). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 2002 and 2011. The shoreline positions have been previously published, but the slopes have not. A reference baseline was defined and then evenly-spaced cross-shore beach transects were created. Then all data points within 1 meter of each transect were associated with each transect. Next, it was determined which points were one the foreshore, and then a linear regression was fit through the foreshore points. Beach slope was defined as the slope of...
In October 2023, the U.S. Geological Survey Idaho Water Science Center (IDWSC), in cooperation with Lucky Peak Power Plant Project (LPPPP), completed bathymetric and topographic surveys at two dam intake structures using multibeam bathymetry and boat-mounted Light Detection and Ranging (LiDAR). Dam operators indicated a possibility that sediment aggradation was occurring near the intake structures that allow water to pass through the dam. The bathymetric and topographic data generally include complete coverage near the intake structures and banklines near Lucky Peak Dam.

In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S. Geological Survey (USGS) in cooperation with the NCDOT, conducted a streambank light detection and ranging (lidar) survey of the streambanks of the French Broad River in November of 2019, approximately two months before construction began. The survey extended from 300 meters (m) upstream to 700 m downstream from the bridge. Two georeferenced lidar scans were collected; one of the right-descending bank and one of the left-descending bank. Three-dimensional points of the streambank...
