Abstract: A laboratory modeling program has been conducted to evaluate the hydraulic conditions required for backward erosion piping (BEP) to initiate and progress in sandy soils. The first stage of BEP consists of loosening the ...

Abstract: Backward erosion piping (BEP) is a leading cause of levee and dam failures and generally occurs when seepage flow breaks through a defect in the downstream low-permeability blanket layer, causing a shallow erosion channel ...
