Estimated bedload transport rates at Rio Vista and Jersey Point, California, 2011-2020

This data set contains estimates of bedload transport entering San Francisco Bay from the Sacramento-San Joaquin Delta. Bedload was estimated following the methods of van Rijn (1984) for the Sacramento River at Rio Vista (USGS 11455420) and the San Joaquin River at Jersey Point (USGS 11337190). The inputs the van Rijn (1984) equations included:bed-material particle size, bed-form dimensions, depth, and velocity. Bedload was estimated at 15-minute intervals from Water Year 2011 through Water Year 2020. A "low range" estimate and a "high range" estimate were made. The low-range estimate assumes plane bed conditions and uses only grain size to estimate a hydraulic roughness parameter. The high-range estimate incorporates both grain size and bedform dimensions to estimate a hydraulic roughness parameter (using the equations provided by van Rijn, 1984).
