Development of Compounded Surfactant Foam and Its Application in Emergency Control of Piping in Dikes [PDF]
MoleculesPiping is a severe threat to dikes, which can lead to dike failure, and cause significant economic and human casualties. However, conventional measures necessitate substantial labor and material resources.

3D character of backward erosion piping [PDF]
, 2018 Backward erosion piping is an important failure mechanism for cohesive water-retaining structures which are founded on a sandy aquifer. Nowadays, piping research and safety assessments are often based on experimental or numerical modelling using ...

Temporal evolution of backward erosion piping in small-scale experiments
Acta Geotechnica, 2022 Backward erosion piping (BEP) is a form of internal erosion which can lead to failure of levees and dams. Most research focused on the critical head difference at which piping failure occurs.
