Didier Marot, Auteur ; Pierre-Louis Regazzoni, Auteur ; Tony Wahl, Auteur |The jet erosion test (JET) and the hole erosion test (HET) are two tests used to determine soil erodibility classification, and results are commonly interpreted by two distinct methods. A new method based on fluid energy dissipation and on measu[...]

Hong Haï Nguyen, Auteur ; Didier Marot, Auteur ; Fateh Bendahmane, Auteur |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 sensor in order to characterize precisely the initiation and develo[...]

Fateh Bendahmane, Auteur ; Didier Marot, Auteur ; Alain Alexis, Auteur |Within hydraulic earth structures (dikes, levees, or dams), internal seepage flows can generate the entrainment of the soil grains. Grain transportation affects both particle size distributions and porosity, and changes the mechanical and hydrau[...]

Didier Marot, Auteur ; Fateh Bendahmane, Auteur ; Hong Haï Nguyen, Auteur |This paper deals with suffusion process also named internal instability, which takes place inside the soil skeleton. In this process, finer particles of a soil migrate within its own pore spaces. These fine particles can be cohesionless particle[...]

Pierre-Louis Regazzoni, Auteur ; Didier Marot, Auteur |Erosion is one of the main causes of instabilities within hydraulic earth structures. Two types of erosion can be distinguished: suffusion and interface erosion. This paper deals with the interface erosion phenomenon and the Jet Erosion Test is [...]

Stéphane Bonelli, Auteur ; Didier Marot, Auteur |Suffusion is the internal erosion process by which finer soil particles are detached from the solid matrix, and transported through constrictions by seepage flow. At the macroscopic scale, this is a bulk erosion process and corresponds to a sour[...]

Didier Marot, Auteur ; Jacques Garnier, Auteur ; Luc Thorel, Auteur |Suffusion is an internal erosion mechanism, which means detachment and transport of fine particles within the soil skeleton due to hydraulic seepage flows. Different researchers have observed that the value of the critical hydraulic gradient req[...]

Yacine Sail, Auteur ; Didier Marot, Auteur ; Lue Sibille, Auteur |Under internal flow, hydraulic earth structures (dikes, levees, or dams) can incur a migration of particles possibly inducing a modification of hydraulic and mechanic characteristics. With the objective to characterize this phenomenon named inte[...]
