A reach of the Sacramento River near Glenn, California, was selected as a field site to test a sensor payload developed by the U.S. Geological Survey and the National Aeronautics and Space Administration for estimating surface flow velocities in rivers. The payload, called the River Observing System (RiOS), can be deployed from an uncrewed aircraft system (UAS). RiOS includes visible and thermal cameras, a laser range finder, an inertial navigation system, an embedded computer for storing and processing data, and a wireless link for transmitting data to a ground station. This data release includes thermal imagery acquired by RiOS and stored in Robot Operating System (ROS) *.bag files. The bag files are organized...

The watershed data management (WDM) database SC21.WDM is updated with the processed data for the period October 1, 2020, through September 30, 2021. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and discharge) are collected at USGS streamflow-gaging stations in and around DuPage County, Illinois. Hourly precipitation and hydrologic data for the period October 1, 2020, through September 30, 2021, are processed following the guidelines described in Bera (2014) and Murphy and Ishii (2006) and appended to SC20.WDM and renamed as SC21.WDM. Meteorological data (wind speed, solar radiation, air temperature, dewpoint temperature, and potential evapotranspiration)...
Note: this data release is currently being revised and is temporarily unavailable. A hydrodynamic and water-quality model (CE-QUAL-W2) was developed of a 21-mile reach of the upper Illinois River including a 3-mile reach of a major tributary, the Fox River. The CE-QUAL-W2 model is 2-dimensional in the vertical and longitudinal directions and averaged over the lateral direction. Continuous water quality and streamgage data provided time-series data for model boundary conditions. Discrete velocity, cross-section area, and temperature profiles at several locations within the study reach provided model calibration data. The model was calibrated to 2021 and 2022 observed data and validated with 2020 data. Model...

U.S. Geological Survey Northeast Region inland to coastal bathymetric survey data are compiled to create a survey inventory providing survey records including survey system and product information, and links to survey datasets when available. Dataset footprints including this information and showing the location and extent of surveys can be downloaded as a shapefile or geodatabase, and can be accessed through Spatial Services provided here.

Shenandoah National Park, Virginia. Sawed slab of porphyritic greenstone. Slab is from the outcrop on the south side of Skyline Drive at mile 80.9, about 100 yards east of Big Run Overlook in the southern section of the park. Angular to slightly rounded phenocrysts of plagioclase (now albite) occur in the matrix of finer grained albite, chlorite, and epidote displaying relict basaltic fabric. The phenocrysts in this specimen are somewhat larger than those in the porphyritic flows in the Big Meadows-Stony Man Area, but the texture is typical. Specimen collected by Professor Ernst Cloos, The Johns Hopkins University. Photo by J.P. Owens. Figure 14, U.S. Geological Survey Bulletin 1265.

This data release contains 2 shapefiles which include 626 unique shorelines and 3 foredune toes spanning 2016 to 2023 along Minnesota Point, a 9-kilometer long bay-mouth bar at the western end of Lake Superior. Each shoreline represents the intersection line between land and water at a unique time associated with the capture of a satellite image, and these shorelines are used to examine trends in beach width and investigate beach nourishment performance in an accompanying publication (Roland et al., 2024). The shorelines were extracted from 3-meter resolution Planet Labs PlanetScope satellite imagery following the methods of Doherty et al., 2022. A site-specific machine learning model was developed to classify image...

A Bell 407 helicopter with a gyro-stabilized gimbal was used to collect aerial videos of Integrated Water Science basin riverine study sites in 2022. Videos were collected using both natural color and thermal infrared cameras. These videos were used to determine the feasibility of estimating river surface velocity using aerial imagery. Orthomosaic maps were produced from the natural color videos using photogrammetry techniques. Separate child pages were created to provide access to both the videos collected and the orthomosaic maps produced for each IWS basin (Delaware River, Illinois River, and Upper Colorado River).
Note: this data release is currently being revised and is temporarily unavailable. Dataset contains reservoir bathymetry and shoreline topography up to dam crest elevation. Data were collected using small unmanned aerial system (sUAS), multibeam sonar, and terrestrial lidar.
