Abstract
The concrete lozenges are a new technique used to protect slopes. It constitutes a non-continuous mesh mask on the slop, having the effect of collecting and transporting runoff water. Therefore, it allows on the one hand, reducing the quantities of soil loss in the shallow surface, and on the other hand, to minimize the water stagnation time and their infiltration at a depth which will influence the soil shear strength causing significant sliding mode of slope failure. The number and geometry of the lozenges depend of both natural and anthropogenic parameters such as: the nature of the soil, the rainfall zone, the quantity of soil that can be removed by the channel located at the bottom of the slope and the slope geometry. A parametric study is undertaken to define the optimal design of concrete lozenges.
