Summary

These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys." These data include (1) raster digital surface models from 2002, 2009, and 2013 of seven sites along the Colorado River in Grand Canyon and associated digital elevation models of difference (DoDs), (2) landscape information for each of the seven sites as vector polygons, including the site extent, area of bare sediment, flood inundation extent, and area of vegtation, (3) the locations of 113 field validation points used to assess the accuracy of the automated [...]

Purpose

These data provide the software and input datasets required to complete the automated mechanistic segregation as described in the manuscript “Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys” by Alan Kasprak, Joshua Caster, Sara Bangen, and Joel Sankey. The database also contains the location and results from field visits to validation points at seven sites in Grand Canyon used to assess the accuracy of the landscape-based approach (LBA) and the digital elevation models (DoDs) of diļ¬€erence-based approach (DBA) predictions in the workflow.
