Alluvial River Width Variability

Data compilations of bankfull downstream hydraulic geometry for alluvial rivers, lidar derived high-resolution spatial series of bankfull width for 67 sites, and hydrograph metrics for sites with USGS hydrographs. This compilation is composed of three datasets: (1) a compilation of alluvial river geometry at bankfull for a variety of hydraulic attributes; (2) x, y, and z coordinates of channel bank lines for a selection of sites and their associated river widths derived from high-resolution lidar topography; and (3) statistics describing the hydrographs for a subset of the larger compilation. These data are divided into two primary sets, the larger compilation and a smaller set of sites where the bankfull width was derived from lidar topography. For the high-resolution dataset, the data are available as the coordinates of the bank lines, spatial series of distance downstream and bankfull width, and the spatial series filtered for quality.
