Remodified Einstein Procedure for Sediment Load
Publication: Journal of Hydraulic Engineering
Volume 109, Issue 4
Abstract
A procedure has been developed to calculate the total sediment transport rates from the flow and suspended sediment data collected from the sampled zone (by depth integrated sampler). This procedure is a modification of the well‐known “Modified Einstein Procedure.” The two major modifications are that (1) The z components in the Modified Einstein Procedure, based on the 0.7 power of the fall velocity, were replaced with a regression equation to be determined by actual field data; and (2) an optimization procedure with constraints was included to minimize the difference between the measured and calculated suspended sediment rates in the sampled zone. Using measured loads from large rivers, a comparison of suspended sediment loads calculated by the two methods indicates that this Remodified Einstein Procedure is superior to the Modified Einstein Procedure. Results from this study also indicated that sediment load in unsampled zone for large rivers can exceed the measured sediment load in sampled zones.
