ABSTRACT
Noncohesive sediments move as individual particles, whereas cohesive sediments (< ~ 0.01 mm in size) usually transport in flocs that consist of fine particles irregularly bonded by interparticle electrostatical forces and undergo continuous, dynamic aggregation and disaggregation. When cohesive and noncohesive sediments are mixed, interactions between them play an important role, and the sediment mixture experiences much more complex transport processes. Researchers and engineers have encountered significant challenges when dealing with such mixed sediments which widely exist in estuaries, coastal inlets, reservoirs, rivers, uplands, etc. Presented in this paper is a state-of-the-art review of recent advances in experiments, formulas and models of mixed cohesive and noncohesive sediment transport.
