This workbook contains spatial data on the hydrology, sedimentology, and vegetation extent within the Colorado River corridor from 60 to 78 miles (97 to 125 kilometers) downstream from Glen Canyon Dam, Arizona. In combination with the accompanying MATLAB scripts, these data were used to generate the results within the accompanying manuscript (Kasprak et al., Quantifying and Forecasting Changes in the Areal Extent of River Valley Sediment in Response to Altered Hydrology and Land Cover). Specifically, the datasets include (a) the daily mean or estimated/measured maximum discharge for the Colorado River at Lees Ferry (USGS #09380000) from 1921 to 2016, (b) the estimated daily maximum discharge for the future period...
These data were compiled to model the area of exposed, bare sand along 168 km of the Colorado River between Glen Canyon Dam and Bright Angel Creek, Arizona. Objective(s) of our study were to develop and validate four models of exposed sand area for the study reach, respectively based on 1) single-day maxiumum river discharge, 2) multiple-day river discharge patterning, 3) field-observed wind velocities, and 4) remote-sensing measured trends in vegetation areas. These data represent biophysical patterns and processes in the study reach; included here are a) daily records of maximum discharge of the Colorado River at Lees Ferry, Arizona, b) river discharge and exposed sand area throughout the study reach, c) scaling...
