ABSTRACT:

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.

ABSTRACT:

Data compilation of bankfull downstream hydraulic geometry for alluvial rivers. File includes bankfull hydraulic geometry variables (slope, median grainsize, width, depth, and discharge) with short citations and site names. Full citations to the papers and reports from which these data were compiled are contained within the second sheet.

ABSTRACT:

Recirculating flume experiments tracking the evolution of sand bed forms through repeat 2d sonar scans. Experiments track change in bed form geometries across abrupt and gradual water discharge changes.

ABSTRACT:

This dataset contains positions of RFID-equipped coarse sediment tracer particles before and after floods at the single flood to annual timescales in the Mameyes River, PR. Please see accompanying metadata file "RFID Tracer Documentation" (.txt). Tracer particle locations are available in both a cartesian coordinate system (UTM), as well as a streamwise normal coordinate system.
