... seepage flow (Sherard, 1979 ; Kenney and Lau, 1985 , 1986). To evaluate internal stability (IS) of such broadly graded materials, laboratory IS erosion tests are often conducted in a rigid-wall permeameter. Four gradations (KLY′, UA, UB, and SC) and their corresponding scalped-and-replaced...

... proposes a novel tortuosity–porosity model for estimating tortuosity in saturated porous media. Syringe tests were conducted by simulating seepage flow through a porous medium under Darcy’s law. The tortuosity was achieved after determining the porosity and permeability using the volumetric saturation...

To maximise the efficiency of seepage tests for different solutes (salt and a surfactant...

...J. Prasomsri; T. Shire; A. Takahashi Internal instability or suffusion is one of the mechanisms of internal erosion in cohesionless soils, which is described by the loss of integrity of soil by seepage flow and is associated with the migration of finer particles. The contribution of the non-plastic...

...Jaromír Říha; Lubomír Petrula; Mario Hala Heave is a type of deformation that occurs due to seepage, which may evolve into backward erosion piping and eventually lead to the total collapse of a hydraulic structure. It may occur downstream of the hydraulic structure when uniform non-cohesive soil...

... values, which are dependent on biopolymer concentration and the ageing period. Thus, it can be concluded that the application of biopolymers as temporary seepage barriers for the protection of many geotechnical works (such as foundations) and underground structures is highly beneficial. The use...

...A. Mehdizadeh; M. M. Disfani; R. Evans; A. Arulrajah Suffusion is defined as the migration of fine particles caused by seepage flow through pre-existing pores of a soil structure made of coarse particles. This particle transportation changes the fine particle content and its distribution, possibly...

...M. Ouyang; A. Takahashi Suffosion is a seepage-induced instability phenomenon whereby fines are eroded away through the constrictions formed by coarse particles, resulting in a reduction in soil volume and a change in hydraulic conductivity. In this study, upward seepage tests were performed on gap...
