This child data release includes hyperspectral and RGB images acquired from an Unmanned Aircraft System (UAS) during an experiment performed at the USGS Columbia Environmental Research Center, near Columbia, Missouri, on April 2, 2019. The purpose of the experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) tracer from various types of remotely sensed data in water with varying levels of turbidity. Whereas previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, the Missouri River is much more turbid and the reflectance signal associated with the sediment-laden water could obscure that related to the presence and amount...

Data consist of geolocation, temperature, turbidity, time, and dye concentrations collected at four downstream locations from Rhodamine WT dye injection point on Yellowstone River in June 2017

This data release contains river bed surface grain size measurements, water-surface elevation measurements, and digital elevation models (DEMs) for select reaches of the Big River, Missouri. These data were collected in support of research assessing the hydraulic conditions of freshwater mussel habitat in the Big River. The individual metadata associated with each data type describe the process steps, data inputs and sources, and the locations where the data were collected.

This dataset contains cross-sectionally averaged flow metrics from measurements made with acoustic Doppler current profilers (ADCP) on the Missouri River near Wolf Point, MT during 2018 and 2019. Each data point represents a single-pass measurement with a boat-mounted ADCP driven from bank-to-bank along lateral transects spaced ~15 meters apart along a 33 kilometer reach. The measurements were collected as part of a bathymetric survey in which two USGS survey boats were each mounted with an ADCP and single beam echosounder that were deployed simultaneously. Cross-sectionally averaged flow metrics such as velocity, depth, and temperature along with the total measured discharge and starting coordinate of the measurement...

This data release contains numerous shapefiles that describe baseline characterization of the physical attributes of the riverine ecosystems in two national parks – Ozark National Scenic Riverways (ONSR), Missouri, and Buffalo National River (BNR), Arkansas. The individual metadata associated with each shapefile describe in detail the specific process steps, source inputs for the data, and the specific river the data characterize.

The dataset is a digital elevation model (DEM) for a 20-km reach of the Missouri River downstream from Wolf Point, MT. Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single-beam sonar surveys of the channel bed in June 2018 and terrestrial light detection and ranging (LiDAR) surveys of channel banks in September 2018. Floodplain topography was generated from airborne LiDAR data collected in November 2012 by Furgo Horizons, Inc. for the U.S. Army Corps of Engineers.
Data set contains depth and velocity grids centerpoints generated from hydrodynamic model (SRH-2D) simulations run for a range of discharges. Date range corresponds to month(s) that bathymetric survey was performed. Three study reaches were considered in this analysis: the Fairview reach of the Yellowstone River, MT, the Miami and Lisbon-Jameson reaches of the Lower Missouri River. Data and application are described in detail in accompanying journal article (Erwin et al., 2017).
