Entraining Flow of a Concentrated Benthic Suspension: Computations with the Prandtl Mixing-Length Model

The Prandtl mixing-length model of turbulent exchange of mass and momentum is applied to calculate the entrainment of overlying water into a layer of suspended fine sediment at a horizontal bed. In the field the flow and turbulence in such a concentrated benthic suspension (CBS) are driven by a streamwise pressure gradient resulting from the...

Hindered settling and consolidation of mud - analytical results

The theory of hindered settling from a suspension developed by Kynch (1952) is known to satisfactorily describe the settling and primary consolidation of mud. This theory, in which effective stresses are disregarded, is reviewed for this purpose, and some analytical results for interface formation and consolidation are obtained. In particular it...
