Levees/earth dams are critical infrastructures for supplementing clean water, flood
management, and energy production, prone to progressive failures due to internal erosion …

This paper presents a large-scale backward erosion piping experiment aimed at studying
the erosion rate. This temporal aspect of piping complements previous research that focused …

While backward erosion piping (BEP) and slope instability failure mechanisms have been
investigated independently, they are not analyzed concurrently despite that the response of …

ABSTRACT A series of upward seepage tests on sand specimens with three grain size
distributions (ie, two uniform soils and one gap-graded soil) were conducted to better …

An inverse analysis procedure has been developed to interpret collected pore pressure data
and observations during backward erosion piping (BEP) initiation and progression in sandy …

Backward erosion piping is an important failure mechanism for cohesive water-retaining
structures which are founded on a sandy aquifer. This paper studies the effect of the sudden …

Gap-graded soil, classified as internally unstable soil, is susceptible to hydraulic failure due
to the migration and erosion of fine particles through the coarse particle matrix at a relatively …

Suffusion and pipping are two main causes for dam and dike failures. In this study, a
permeameter with transparent specimen tank was developed, which allowed internal …

A series of upward seepage tests on unreinforced and reinforced sand specimens was
conducted to investigate the influence of soil density and fibre parameters (ie fibre contents …

Piping is a major failure mechanism in both dams and dikes. In this work, we develop a
transparent specimen tank that allows a camera to clearly record the piping formation …
