The total eroded mass, erosion rate and skeleton deformation were comparatively analysed, and the mesoscopic mechanism was discussed preliminarily. The results showed that the hydraulic gradient affected...

...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...

... coastal erosion in shallow waters. A set of six sand samples sloped at 45° was prepared in an acrylic flume apparatus and tested against erosional and accretional surging waves, and the results showed that MICP was able to limit soil erosion to less than 5% for both wave types. To ensure the generation...
