Disposable flow through slide chamber
Micron and Microscopica Acta, 1988Abstract An inexpensive disposable flow through slide chamber using double face tape is described. The chamber allows observation of the free movement and interaction of microscopic invertebrates and has sufficient chamber volume to sustain life for adequate study.

Quarterly Journal of Engineering Geology and Hydrogeology, 2002
The paper describes a slope failure in granular colluvium, together with its geomorphological, seismic and geotechnical setting. The predictions from conventional geotechnical slope stability analyses, taking into account topography, pore pressure and seismic effects, are compared with the observed pattern of instability.

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.

Flood Flow Downstream from Slide
Journal of the Hydraulics Division, 1971Mass wasting, or the gravitative transfer of earth material toward and into streams, not only reshapes the landscape with a scar but has a pronounced and nearly immediate effect on local streamflow. This report notes the effect of a landslide of the soil avalanche type from a wooded hillside, on the flow rate of a small stream draining a 20-acre basin,

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.

Liquefaction flow slides in large flumes
International Journal of Physical Modelling in Geotechnics, 2019Liquefaction flow slides in sand have been investigated during an extensive experimental research programme during the period 1973–1977 on behalf of the design of the storm surge barrier in the Oosterschelde estuary. The programme included more than a hundred tests in large- and medium-sized flumes on submerged, loosely packed sand bodies.

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.

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 ...

Sliding mode observer for fluid flow
2017 IEEE Conference on Control Technology and Applications (CCTA), 2017Many phenomena in science and engineering are described using partial differential equations. However, for the systems modeled by PDEs, having access to the states of the system can be challenging due to technical difficulties such as lacking enough sensors in the system. In this paper the problem of estimating the parameters of fluid flow described by

Lubricated sliding dynamics: Flow factors and Stribeck curve
The European Physical Journal E, 2011We study the fluid flow at the interface between elastic solids with randomly rough surfaces. We derive (approximate) analytical expressions for the fluid flow factors which enter in the equation describing the fluid flow, and for the frictional shear stress factors which enter in the equation for the frictional shear stress.
