Original Abstract

Backward erosion piping is driven by seepage forces acting on the downstream end of a seepage path. Three types of sand with grain sizes of 0/2, 0,25/2and 0,25/1 were tested in the new experimental device. During 42 tests the progression of the seepage path, the piezometric heads and the eroded material were observed by two synchronous cameras, set of piezometers and pressure cells. An empirical formula for the rate of blackward erosion piping was proposed. Comparsion of lateral erosion characteristics with the available literature provided quite a good fit.
