DOI: 10.1007/s11440-019-00789-8
Abstract: Behaviour of granular soils subjected to internal erosion involves complex coupling between solid–fluid interaction, skeleton deformation and microstructural evolutions. This paper presents a micro–macro investigation on suffusion in idealized gap-graded and well-graded soils using the coupled… read more here.

DOI: 10.1007/s12517-020-06193-x
Abstract: Suffusion is a particular case of internal erosion due to water seepage through a porous media, which is a main cause of the failure of dam and embankment. There are a lot more to understand… read more here.

DOI: 10.1007/s12517-024-11988-3
Abstract: Suffusion is arguably the most complicated type of internal erosion. Although there are several popular assessment methods, the most realiable assessment is possibly still laboratory testing. However, there is not a standardised test for suffusion… read more here.

DOI: 10.1016/j.compgeo.2020.103617
Abstract: Abstract A new fluid–solid coupled numerical approach by combining the Dynamic Fluid Mesh method with DEM (discrete element method) is applied to simulate suffusion. The fluid mesh is generated according to the soil skeleton formed… read more here.

DOI: 10.1016/j.sandf.2017.08.017
Abstract: Abstract Suffusion is an important mechanism that leads to the failure of hydraulic structures such as dams and levees. To evaluate the onset conditions, i.e., the critical hydraulic gradient of the suffusion, a set of… read more here.

DOI: 10.1016/j.sandf.2018.05.008
Abstract: Abstract Suffusion or internal instability is a major form of internal erosion in cohesionless soils. Hypotheses based on experimental work suggest complex micro-scale influences of stress and material fabric on suffusion. This study presents the… read more here.

DOI: 10.1139/cgj-2023-0484
Abstract: In recent years, local scour has occurred on the pier foundations of river bridges during heavy rain and river flooding, often resulting in bridge collapse. This study focused on the characteristic displacement, called “delayed displacement”,… read more here.

DOI: 10.1144/qjegh2023-124
Abstract: Suffusion involves the migration of fines within the soil matrix, which may cause many types of geohazards. Localized characterization of suffusion is necessary because suffusion is inhomogeneous. However, existing studies on localized characterization have primarily… read more here.
