“…The twentieth century studies of Miesel, Mu ¨ller-Kirchenbauer and Hanses [21,29,31] report very limited data on the development over time. More recently, several researchers studied pipe progression rates (dl/dt) experimentally [3,35,36,38,41,51]. Robbins et al [38] used cylindrical flumes and correlated progression rates to seepage velocity and void ratio.…”

“…Robbins et al [41] analyzed progression rates in small-scale flumes with a slope-type exit, for a wide range of grain sizes. Finally, Pol et al [36] report pipe progression rates in a large-scale experiment. These studies [3,35,38,41,51] show that the progression rate is related to head difference, grain size and degree of compaction.…”

“…Scaling requires relating the progression rate to local, scale-independent conditions. Only Robbins et al [38] and Pol et al [36] evaluated local hydraulic gradients at the pipe tip, which are considered scale independent erosion criteria. The other studies only present global hydraulic gradients.…”

“…The experiments include three fine, uniform sands with characteristics as shown in Table 1. The FPH sand was also used in Pol et al [36]; the Baskarp B25 sand was used in Akrami et al [2] and Rosenbrand et al [42]. Grain sizes were determined by dry sieving.…”

Backward erosion piping (BEP) is a form of internal erosion which can lead to failure of levees and dams. Most research focused on the critical head difference at which piping failure occurs. Two aspects have received less attention, namely (1) the temporal evolution of piping and (2) the local hydraulic conditions in the pipe and at the pipe tip. We present small-scale experiments with local pressure measurements in the pipe during equilibrium and pipe progression for different sands and degrees of hydraulic loading. The experiments confirm a positive relation between progression rate and grain size as well as the degree of hydraulic overloading. Furthermore, the analysis of local hydraulic conditions shows that the rate of BEP progression can be better explained by the bed shear stress and sediment transport in the pipe than by the seepage velocity at the pipe tip. The experiments show how different processes contribute to the piping process and these insights provide a first empirical basis for modeling pipe development using coupled seepage-sediment transport equations.

“…Over the past century, research has revealed many aspects of the erosion process (e.g., Refs. [5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In spite of the complexity of the BEP process, these studies have delivered a relatively complete description of the underlying physics driving BEP progression.…”
