Unema, J.A., Topping, D., Caster, J., and Kohl, K.A., 2018, Geomorphic Change-Sediment Transport Data for the Little Colorado River, Arizona, USA: U.S. Geological Survey data release,


These data were compiled to accompany flow modeling work on Little Colorado river above the mouth (USGS gage 09402300). The data include topographic data collected by LIDAR and total station in June 2017, high water marks from nine historic floods, and 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 are divided into nine distinct sets based on elevation profile.

The purpose of these data are for flow modeling efforts to better understand historic flooding and geomorphic change on the Little Colorado River above the mouth (09402300) gaging station. They will also be used to better understand historic flood discharges and provide a baseline data set for future geomorphic change detection.
