Abstract: A method is presented for estimating the modulus of compacted rockfill in dams based on the particle size, unconfined compressive strength of the rock, compaction layer thickness, compactive effort, and the applied vertical ...

Abstract: A method is presented for assessing the particle size distribution of the filters in a dam compared to the soil the filter is protecting, to determine whether the filters are sufficiently fine to give no, excessive, or ...

Abstract: Suffusion is the process by which finer soil particles are moved through constrictions between larger soil particles by seepage forces. Soils susceptible to suffusion are described as internally unstable. This technical ...

Abstract: A one‐dimensional model of the sedimentation and desiccation of high‐clay‐content, subaerially deposited tailings is described. The approach is semi‐empirical and predicts average density and water content of a layer of ...

Abstract: The slot erosion test and the hole erosion test have been developed to study the erosion characteristics of soil in cracks in embankment dams. The erosion characteristics are described by the erosion rate index, which ...

Abstract: A method is presented for the approximate estimation of the time for progression of internal erosion and piping, and development of a breach leading to failure in embankment dams and their foundations. The method accounts ...

Abstract: Concentrated leak erosion occurs in transverse cracks in dams when the reservoir rises above the base of the cracks. As water flows through the crack, the sides of the crack will erode if the hydraulic shear stress exceeds ...
