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

Quantifying and forecasting changes in the areal extent of river valley sediment in response to altered hydrology and land cover
In river valleys, sediment moves between active river channels, near-channel deposits including bars and floodplains, and upland environments such as terraces and aeolian dunefields. Sediment availability is a prerequisite for the sustained transfer of material between these areas, and for the eco-geomorphic functioning of river networks in general. However, the difficulty of monitoring sediment aAuthorsAlan Kasprak, Joel B. Sankey, Daniel Buscombe, Joshua Caster, Amy E. East, Paul E. Grams - Connect
