Hydraulic Erosion Rate of Reinforced Tailings: Laboratory Investigation and Prediction Model

Figure 5

Tailings erosion phenomena with different geogrid spacing. (a) The front end of the sample begins to erode. (b) The front end of the sample is flushed, and the tailings behind the second layer of reinforcement are stacked. (c) Concavity of tailings behind the first layer of the band. (d) Backward movement of tailings ridge behind the second layer.
