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 System (GNSS) surveys were performed using a local base station associated with the streamgage and Trimble R8 and R10 receivers while wading the channel at cross section 5. The survey data were postprocessed by performing the National Oceanic and Atmospheric Administration Online Positioning User Service (OPUS) correction of the static observations collected by the base and adjusting all the survey points accordingly. The survey data were exported to comma separated text (.csv) files, and the resulting file contains a survey point identification, spatial coordinates, elevations in meters above North American Vertical Datum of 1988, and a descriptive code for each point number. The data release also provides a channel cross-sectional area for each river stage in 0.01-meter increments derived from the survey data.
