Topographic data, historical peak-stage data, and 2D flow models for the lowermost Little Colorado River, Arizona, USA, 2017 These data were compiled to accompany flow modeling work on Little Colorado river above the mouth (USGS gage 09402300). The data include example models in FaSTMECH and SToRM solvers in the iRIC framework, topographic data collected by LiDAR and total station in June 2017, and high water marks from nine historic floods. Other data also include location and other information for control points and gage structures. Topographic data include ground topography collected by LiDAR and channel bathymetry collected by total station survey of a 2500 meter reach of the Little Colorado River ending near the confluence with the Colorado River. High water mark data were collected by USGS personnel using total station surveys and... Categories: Data; Tags: Arizona, Coconino County, Colorado River, Grand Canyon, Hydrology, All tags...

The data consist of a baseflow longitudinal profile of the lowermost 22 km of the Little Colorado River. This profile was digitized from 10 map plates from the Horizons Inc Aerial Mapping Professionals 1990-1992 Overflight data report produced for Glen Canyon Environmental Studies.

The best-fit discharge for this flood is 3,500 ft3/s. Other data include topographic cross-section data, control points, and high-water marks collected by RTK GPS, and selected photographs of the survey. The location of this survey is a ~300-meter reach of Sand Creek ending at the upstream side of the Shell Creek Stock Trail bridge. Evidence of additional likely coincident floods on tributaries that enter Sand Creek between the Shell Creek Stock Trail bridge and the confluence of Sand Creek with the Little...

Sand Creek, USGS Science Data Catalog (SDC), United States, Wyoming, Yampa River, flow modeling, inlandWaters, topography, Fewer tags Surveyed coordinates and elevations in a 2020 resurvey of previously established cross sections on the Green River between Jensen and Ouray, Utah These data were compiled for/to National Park Service and Upper Colorado River Endangered Fish Recovery Program. Objective(s) of our study were to resurvey previously established cross sections on the Green River, Utah, in, and upstream, from Ouray National Wildlife Refuge to document changes in channel width, depth, and cross-sectional area. These data represent the 2020 resurvey coordinates and elevations of previously established cross sections (1994 - 1996) on the Green River. These data were collected in the Green River between Jensen and Ouray, Utah from October 11-16, 2020. These data were collected by Ronald Griffiths and Joel Unema from the U.S. Geological Survey using real-time kinematic (RTK) GPS positioning....

Objective(s) of our study were to resurvey previously established cross sections on the Yampa and Little Snake rivers in the Deerlodge Park area to document changes in channel width, depth, and cross-sectional area. A secondary purpose of this study was to document the location of the cross-section endpoints using modern Global Positioning System (GPS) measurements so that future researchers may easily replicate these surveys. These data represent the 2017 resurvey coordinates and elevations of previously established cross sections on the Little Snake and Yampa rivers. These data were collected in Lily...
