...Robert D. Stedtfeld; Glenn E. McCreery; Alan T. Stadler; Daphne L. Stoner; Paul Meakin A geotechnical centrifuge was used to investigate unsaturated multiphase fluid flow in synthetic fracture apertures under a variety of flow conditions. The geocentrifuge subjected the fluids to centrifugal forces...

..., the infiltration kinetics within a fracture are not always properly scaled. The work clearly illustrates the influence of contact angle variability, pinning forces and inertia on the physics of DNAPL behavior in an idealized fracture. geotechnical engineering Centrifuge DNAPL Fractures Flow Experimental...

... a complete system including riverbed and hydraulic gradient in the sand layer. The groundwater flow has been manipulated by adapting sand layers consisting of different types of sand. Points of research are the determination of length and location of the uplift zone and the influence of material...

...P. Sentenac; R.J. Lynch; M.D. Bolton Side-wall leakage - the preferential flow of water or pollutants near the wall of a soil column - has been studied using in-situ fibre-optical detection of a dye solution at the boundary and in the centre of a soil column. A difference in flow velocity...
