Laboratory Investigations of the Mechanisms of Groundwater Seepage Erosion and Piping in Cohesive Soils
Seepage and soil piping are two mechanisms that can cause streambank erosion and failure. Groundwater seepage can cause erosion either by undercutting or "pop-out" failure. The objective of the seepage study was to utilize a constant-head soil box packed with sandy loam soils at prescribed bulk …

A Study on the Long-Term Performance of Seepage Barriers in Dams
… gradients around the boundaries of the barrier, and through any windows or defects in the barrier. The result is increased water pressures and hydraulic gradients behind and around the barrier. These increased pressures and gradients have potential to provide the catalyst for initiation of …

Investigation of the Ability of Filters to Stop Erosion through Cracks in Dams
The ability of a filter to stop erosion through cracks in the core of a embankment dam requires that the filter be graded so that it will restrain movement of particles from the core, and that the filter be truly cohesionless, so that it will not crack even when subjected to the same types of …
