Soil particle density was observed as the major factor controlling the development of internal erosion, notwithstanding high permeability values of some of the materials.

WebbA capillary model was developed to predict under what conditions piping versus plugging is likely to occur as a result of clay particle dispersion in soils. In the intermediate size range, i.e., particles too small per se to clog pore constrictions and too large to wash through unimpeded, the outcome depends strongly on the concentration of dispersed particles in … WebbTerzaghi identified two types of piping for vertical flow in horizontal terrain: backward erosion and heave.Backward erosion initiates when the vertical hydraulic gradient at the … bar uk jobs
