Velocity profiles and river discharge for cross sections on the Arkansas and South Platte Rivers in Colorado and the Salcha and Tanana Rivers in Alaska

This dataset includes vertical velocity profiles and river discharges at cross sections of interest acquired at the Arkansas and South Platte Rivers in Colorado and the Salcha and Tanana Rivers in Alaska. Velocity measurements were measured at various depths at the y-axis, which is the vertical in the cross section where the maximum velocity (umax) occurs. When wading was possible, veloci

Drone- and ground-based measurements of velocity, depth, and discharge collected during 2017-18 at the Arkansas and South Platte Rivers in Colorado and the Salcha and Tanana Rivers in Alaska, USA

The U.S. Geological Survey (USGS) is actively investigating the use of innovative remote-sensing techniques to estimate surface velocity and discharge of rivers in ungaged basins and river reaches that lack the infrastructure to install conventional streamgaging equipment. By coupling discharge algorithms and sensors capable of measuring surface velocity, streamgage networks can be establis...

Surface velocity data acquired from QCam (drone-based Doppler velocity radar) for the Arkansas and South Platte Rivers in Colorado and the Salcha and Tanana Rivers in Alaska

This dataset contains data collected during science flights using the drone-based QCam, which is a Doppler (velocity) radar designed to measure surface velocity and compute river discharge when channel bathymetry is known. Five science flights were conducted on four rivers including the Arkansas and South Platte Rivers in Colorado and the Salcha and Tanana Rivers in Alaska. Data are present...

Wading survey of bed topography, gage height, and cross-sectional area for the Arkansas River near Parkdale, Colorado

This dataset contains survey data including wading and real-time kinematic (RTK) Global Positioning System (GPS) of water surface elevation and channel bed topography at cross section 5 (xs5) on March 20, 2018, which is adjacent to the U.S. Geological Survey (USGS) streamgage at Arkansas River at Parkdale, Colorado (USGS 07094500). The RTK Global Navigation Satellite Sy

Cross-Section Geometry and Sediment-Size Data from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado, 2019

This dataset contains cross-section geometry and sediment-size data collected in the fall of 2019 from Muddy Creek and North Fork Gunnison River below Paonia Reservoir, western Colorado. Six cross sections were surveyed using Real-Time Kinematic Global Navigation Satellite System (RTK-GNSS) methods to document channel geometry below Paonia Reservoir. One cross section was surveyed on Muddy...

Concentration of inorganic chemical elements associated with suspended sediment at Muddy Creek below Paonia Reservoir, Gunnison County, Colorado, U.S. Geological Survey site number 385626107212000

Dataset includes the analysis results of 49 inorganic chemical elements bound to suspended-sediment particles below Paonia Reservoir during a sediment release in September 2017. Suspended-sediment samples were collected at U.S. Geological Survey (USGS) station number 385626107212000 by following data collection procedures and protocols in Edwards and Glysson (1999). The samples were freez

Geospatial Fabric for National Hydrologic Modeling, version 1.1

This U.S. Geological Survey (USGS) data release consists of two hydrographic datasets with spatial modeling units consistent with the National Hydrologic Model (NHM) Geospatial Fabric for National Hydrologic Modeling (abbreviated within this document as GFv1, Viger and Bock, 2014). The two datasets found as subpages to this landing page are 1) the GIS (geographic information s

GIS Features of the Transboundary Geospatial Fabric (TGF)

The Transboundary Geospatial Fabric (TGF) is a dataset of spatial modeling units consistent with the Geospatial Fabric for National Hydrologic Modeling (abbreviated within this document as GFv1, Viger and Bock, 2014). These features were derived from National Hydrography Dataset Plus High Resolution data (NHDPlus HR, U.S. Geological Survey [USGS], 2018) in the following co

GIS Features of the Geospatial Fabric for the National Hydrologic Model, version 1.1

The Geospatial Fabric version 1.1 (GFv1.1 or v1_1) is a dataset of spatial modeling units covering the conterminous United States (CONUS) and most major river basins that flow in from Canada. The GFv1.1 is an update to the original Geospatial Fabric (GFv1, Viger and Bock, 2014) for the National Hydrologic Modeling (NHM). Analogous to the GFv1, the GFv1.1 described here inclu

Longitudinal Hydrophone Profile Data on the Upper Colorado River, Colorado, June 6 to 8, 2019

In 2019, the U.S. Geological Survey, in cooperation with the Upper Colorado River Wild and Scenic Stakeholder Group, studied the magnitude and recurrence interval of streamflow needed to initiate bed movement of gravel-sized and finer sediment in a segment of the Colorado River in Colorado to better understand sediment movement and its relation to flow regimes of the river. Bed movement occ...
