Yampa River channel elevation at Deerlodge Park, CO

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The U.S Geological Survey Scientific Investigations Map provides raster data that can be used to assess channel response to streamflow alteration scenarios indicated from computer modeling of streamflow and sediment-transport conditions. Each 0.3-meter raster cell represents the surface elevation as derived bathymetric and topographic surveys and verified with RTK GPS. The Yampa River in northwestern Colorado is the largest, relatively unregulated river [...]

本数据集发布于2016年10月1日之前，符合美国地质调查局（United States Geological Survey, USGS）制定的科学数据评审、审批与发布政策要求，该政策详见USGS《测量手册》第502.8章《基础科学实践：科学数据发布的评审与审批》。美国地质调查局科学调查图（U.S Geological Survey Scientific Investigations Map）提供的栅格数据，可用于评估河道对基于径流与泥沙输运条件计算机模拟所得的径流变化情景的响应。每个0.3米分辨率的栅格单元，代表通过水深测量与地形测绘获取、并经实时动态差分GPS（Real-Time Kinematic GPS, RTK GPS）验证的地表高程。位于科罗拉多州西北部的扬帕河（Yampa River）是该区域规模最大、受调控程度较低的天然河流[...]
