A sand boil is a cone of granular material deposited on the ground surface around concentrated points of vertical seepage. Sand boils often form downstream of embankments during flood events, creating unfiltered seepage exits that may lead to initiat

The critical shear stress and erodibility of soil are fundamental parameters for modeling embankment breaching. Unfortunately, very few studies have examined the erosion characteristics of soils consisting predominantly of particles larger than sand.

Using a confined flume device, an experimental study investigated the critical horizontal gradient of soils obtained from a site identified as potentially vulnerable to backward erosion piping (BEP). Tests were conducted on glacial outwash material o

Backward erosion piping (BEP) is a common hazard along artificial levees in the Lower Mississippi Valley (LMV). This study applies an empirical assessment of overbank deposit thickness, als...

A new fragment type is developed using finite elements, with results presented in the form of charts for the estimation of seepage beneath levees and other water-retaining structures. The chart solutions are then compared with existing approximate so

Results of an experimental study are presented in which the horizontal, critical gradient required for backward erosion piping of fine gravel was measured. A horizontal flume was constructed that allowed samples to be subjected to a vertical confinin
The orientation of constructed levee embankments relative to alluvial swales is a useful measure for identifying regions susceptible to backward erosion piping (BEP). This research was conducted to create an automated, efficient process to classify p

It is often of great interest in geomechanical analysis to model localized phenomena, such as strain concentrations along failure planes or hydraulic gradient concentrations near discontinuities and exit points. Focus in recent years on massively par

Backward erosion piping is a leading cause of levee failures, second only to overtopping, and is therefore of great concern to engineers involved in flood control. Backward erosion piping r...

A new type of laboratory test has been developed for measuring the local hydraulic conditions required for the progression of backward erosion piping, an internal erosion mechanism for water-retaining structures. The device consists of clear acrylic
