    In the above discussion, we assumed that the main loading of the structures was external, because of a large permeability of the rocky slope structures. When we consider coherent, semi-permeable, placed block revetments or impervious asphalt or concrete structures, the external loading also leads to internal loadings. The failure mechanisms thus become much more complex. We will not consider this here, but it is interesting to note that the empirical formulations for the semi-impermeable structures also fall back on Iribarren’s mobility parameter.
