  • River Valley Sediment Connectivity Data, Colorado River, Grand Canyon

    Metadata Updated: March 22, 2021

    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 2016-2036, (c) the pre-dam hydrograph record from 1921-1963, (d) the post-dam hydrograph record from 1963-2016, and the pre- and post-dam extent of bare sand within the study reach, accounting for the influence of vegetation encroachment during that time.
