Channel and floodplain cross-section and bed-elevation data for the Green River in Echo, Island, and Rainbow Parks, Dinosaur National Monument, Colorado and Utah

These data were compiled to determine the rate and magnitude of channel-planform change, and the topographic change of the channel and floodplain in Echo, Island, and Rainbow Parks within Dinosaur National Monument between the 1990s and 2019. The objective(s) of our study were to analyze geomorphic change within Echo, Island, and Rainbow Parks to determine the magnitude and style of channel change with respect to the past two decades of combined streamflow from Flaming Gorge Dam and the relatively unregulated Yampa River. These data represent river channel planform delineations made within a geographic information system, and topographic channel and floodplain data collected using total stations, depth sounders, Real-Time Kinematic GNSS, and multibeam sonar. These data were collected in June 2019.

本数据集汇编的目的在于明确1990年至2019年间，恐龙国家纪念地（Dinosaur National Monument）内回声公园（Echo Park）、艾兰公园（Island Park）与彩虹公园（Rainbow Park）的河道平面形态变化速率与幅度，以及河道与河漫滩的地形变化。本研究旨在分析上述三座公园内的地貌变化，结合过去二十年火焰峡谷大坝（Flaming Gorge Dam）与相对未受调控的扬帕河（Yampa River）的联合径流数据，确定河道变化的幅度与类型模式。本数据集包含在地理信息系统（GIS）中勾勒的河道平面形态界线，以及通过全站仪、测深仪、实时动态全球导航卫星系统（Real-Time Kinematic GNSS）与多波束声呐采集的河道与河漫滩地形数据。所有数据采集于2019年6月。
