Laboratory Analysis of Hyperconcentrations

by Pierre Julien, Colorado State Univ, United States,

Document Type: Proceeding Paper

Part of: Sediment Transport Modeling


The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses on several aspects of laboratory analysis of hyperconcentrations including: flow classification, rheological models, settling velocity of particles, velocity profiles, and resistance to flow. Rheology appears as the common denominator in hyperconcentrated flow research. Further progress in this field can be achieved through better understanding of the rheological properties of hyperconcentrations.
