A sliding–consolidation model for flow slides
Canadian Geotechnical Journal, 1986A model is proposed for the behaviour of flow slides in loose, cohesionless materials in which the debris spreads out as a uniform sheet. Excess pore-fluid pressures are assumed to be generated, for example by undrained loading arising from the collapse of metastable structure, in the source area of the flow slide.

A model for geotechnical analysis of flow slides and debris flows
Canadian Geotechnical Journal, 2010Flow slides and debris flows incorporate a broad range of sediment–fluid mixtures that are intermediate between dry rock avalanches and hyperconcentrated flows. Following a comprehensive review of some existing analytical approaches to debris flow runout analysis, a new analytical model based on energy conservation has been formulated.

Corner flow in the sliding plate problem
Physics of Fluids, 1995The usual formulation of the well-studied sliding plate problem of driven cavity flow involves an unphysical boundary velocity discontinuity at the corners where moving and fixed boundary surfaces intersect. Molecular dynamics simulations of a Lennard-Jones liquid in a cavity driven by the motion of realistic atomic walls at several Reynolds numbers ...

Hydrological and chemical characterization of an earth slide-flow.
2011To understand the origin of instability and the evolution of large and deep earth slide-flows, it is important to define the origin and path of groundwater and the role of the groundwater on the landslide deposit rheology. To achieve these goals it is important characterize, physically and chemically, the bedrock and slope deposits and the groundwater ...

Submarine Flow Slide in Puget Sound
Journal of Geotechnical Engineering, 1992In December 1985, construction began on the offshore portion of the Renton Effluent Transfer System. Under the auspices of the Municipality of Metropolitan Seattle (Metro), treated effluent is pumped to Duwamish Head where the flow is separated into two 1.63-m-diameter steel pipes that extend about 3,050 m offshore into Puget Sound.

Impacts of tailings flow slides
Mine Water and the Environment, 1999This paper describes characteristics of tailings ponds, highlighting situations and events that weaken such facilities, and provides a method for calculating the destructive capacity of tailings flow slides from failed facilities. There are generally two classes of failures.

Seismically Induced Flow Slide on Centrifuge
Journal of Geotechnical Engineering, 1988Some initial results of centrifuge model tests to examine the mechanism causing flow failure of a less permeable layer resting on a more permeable layer, subjected to seismic loading conditions, is presented. The centrifuge model that was subjected to a base motion using a servohydraulic shaker, consisted of a clay layer overlying a sand embankment ...

The Cilfynydd flow slide of December 1939
Quarterly Journal of Engineering Geology, 1998Abstract This paper describes an investigation of the 1939 flow slide in colliery spoil at Cilfynydd Common, South Wales. The investigation concentrated on the geomorphological features and other aspects that were to be destroyed by a proposed reclamation scheme.

Sliding Couette flow in a ribbed annulus
Physics of Fluids, 2016The flow in an annulus driven by the axial movement of one of the cylinders has been studied. The stationary cylinder has been fitted with axisymmetric ribs resulting in the appearance of the centrifugal-force-driven instability which leads to the formation of axial vortices.

1985
So far we have looked almost exclusively at situations in which sediment particles are transported as the result of the drag exerted on them by moving fluid. In these situations, in which the fluid drives the sediment, the concentration of the transported particles is very small overall, although locally it may be high.
