Sediment Transport in Hyperconcentrated Flows in Sand-Bed Streams

by Bobby J. Brown, US Army Corps of Engineers, United States,



Document Type: Proceeding Paper

Part of: Sediment Transport Modeling

Abstract:

This study advances the understanding of sediment transport of bed material discharge in sand bed streams through application of recently developed theoretical concepts related to the effects of high concentrations of suspended sediment on rheological properties of the water-sediment mixture. The study demonstrates the utility of developing empirical adjustment coefficients for fine material concentration (d₅₀ < 0.0625 mm) that can be used in the Colby method for predicting total bed material discharge from gaging and sediment sampling data commonly available to the engineer.
