Abstract: The scattering and diffraction of plane SV waves by circular cylindrical canyons of various depths in an elastic half space is studied in this paper. The canyons studied here range from shallow circular to semicircular ...

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 ...
