Results are presented from permeameter tests involving unidirectional seepage flow
through reconstituted specimens of four widely graded cohesionless soils. The onset of …

Cohesionless granular matter subjected to internal flow can incur an internal erosion by
suffusion characterized by a migration of its finest constituting particles. A series of suffusion …

Internal instability is a phenomenon of fine particle redistribution in granular materials under
the seepage action and consequent change in the soil's internal structure and hydraulic and …

Internal erosion in soils is characterized by a first step of detachment of solid particles from
the granular skeleton under the action of water seepage; then the detached particles are …

Suffusion describes the phenomenon whereby finer particles are eroded through the voids
of coarse particles by the seepage flow. This may cause the deterioration of the hydraulic …

Background Landslide dams formed by rock avalanche processes usually fail by seepage
erosion. This has been related to the complex sedimentological characteristics of rock …

Internal erosion is one of the main causes of instabilities within hydraulic earth structures.
Four internal erosion processes can be distinguished, and this study deals with the process …

An experimental program was set up to study the suffusion process by using a triaxial
erodimeter developed in our laboratory. This device is equipped with a multichannel optical …

Granular soils subjected to seepage flow may suffer suffusion, ie, a selective internal
erosion. Extending the classical approach of poromechanics, we deduce a new form of the …

An optical sensor was designed to measure the fine solid particles concentration contained
in a fluid flow. This sensor is composed of four light-emitting diodes and four associated light …
