Bedload sediment transport was calculated on the Elwha River, Washington to measure the amount of sediment transported along the riverbed during the 2016 water year. Bedload was measured using the Elwha bedload impact plate system (Hilldale and others, 2015). Physical bedload sampling by the U.S. Bureau of Reclamation for system calibration took place during November, 2012; March, May, and June 2013; and April 2014 at the Diversion Weir gauge (Magirl and others, 2015). Early in water year 2016 (year 5) the river formed an avulsion channel across the floodplain on river left, preventing a complete measurement of bedload passing the Diversion Weir gauge. As a result, bedload for water year 2016 (year 5 of the larger study) was estimated using a discharge rating curve to obtain monthly values.
Data were obtained to assess the morphodynamic and sediment budget responses following the removal of two dams in the Elwha River. These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify topographic features.

Bedload sediment transport was calculated using the Elwha bedload impact plate system (Hilldale and others, 2015). Physical bedload sampling for system calibration took place during November, 2012; March, May, and June 2013; and April 2014 at the Diversion Weir gauge (Magirl and others, 2015). Early in water year 2016 (year 5) the river formed an avulsion channel across the floodplain on river left, preventing a complete measurement of bedload passing the Diversion Weir gauge. As a result, bedload for water year 2016 (year 5) was estimated using a discharge rating curve to obtain monthly values. The formula for the discharge rating curve was: BL16 = 2.325 * 10^-7 * Q^5.644, where BL16 = bedload > 16mm in tonnes, Q = discharge at the diversion weir in ft3/s. These techniques did not capture bedload transport of particles smaller than 2 mm, which were estimated from a combination of regional and comparative studies in high-sediment load rivers--including other dam removal studies--using constant ratios of measured bedload to total sediment discharge estimate of 25 percent.
