Within large-river ecosystems, floodplains serve a variety of important ecological functions. A recent survey of 80 managers of floodplain conservation lands along the Upper and Middle Mississippi and Lower Missouri Rivers in the central United States found that the most critical information needed to improve floodplain management centered on metrics for characterizing depth, extent, frequency, duration, and timing of inundation. These metrics can be delivered to managers efficiently through cloud-based interactive maps. To calculate these metrics, we interpolated an existing one-dimensional HEC-RAS hydraulic model for the Middle Mississippi River, which simulated water surface elevations at cross sections spaced...

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 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...

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.
