  "description": "The child item includes discharge measurements, channel area, surface velocities, and derived discharges using the entropy-based probability concept and four image velocimetry algorithms. The probability concept parameter ϕ (phi_ was computed using field methods and derived from pairs of mean and maximum velocities. The dataset provides a comparison of remote sensing-derived discharges versus discrete acoustic Doppler Current Profiler measurements, highlighting the percent errors and mean absolute differences.\n<br>\nEach field site is abbreviated in various files in this data release. File and folder names quickly identify which site a particular file or dataset represents. The following abbreviations are used:\n<ul>\n<li>ACS: Anthracite Creek at Somerset, Colorado, USA</li>\n<li>BRA: Blue River below Dillon, Colorado, USA (collected in August 2023)</li>\n<li>BRJ: Blue River below Dillon, Colorado, USA (collected in June 2023)</li>\n<li>CRG: Colorado River below Glenwood Springs, Colorado, USA</li>\n<li>CRR: Colorado River above Roaring Fork River at Glenwood Springs, Colorado, USA</li>\n<li>ERW: Eagle River below Milk Creek near Wolcott, Colorado, USA</li>\n<li>MCA: Maroon Creek near Aspen, Colorado, USA</li>\n<li>RFG: Roaring Fork at Glenwood Springs, Colorado, USA</li>\n</ul>",
