ABSTRACT.- The evolution of slopes affected by massive landslides. Case study: The right slope of the Secaşu Mic river (in Tău-Secăşel sector).The right bank of Secaşul Mic at Secăşel is remarkable due to the massive, glimee-type, landslides. The landforms that make up the micromorphology of the landslide, represented by the separation escarpment, the long depression on its base, the glimee rows and the front of the landslide, are remodeled by the present processes, depending on the energetic potential provided. In other words, the slope continues its evolution according to present temperate conditions by forming new slide fields, new separation scarps, in the framework of the continuous modeling of glimee rows and of the ancient separation escarpment, without developing new glimee-type landslides. In short, the existence of a slope affected by ancient massive landslide processes, which created several glimee rows, in their turn affected by recent slide processes, like superficial landslides, crumblings, falls, represents nothing else but the superposition of different generations of landforms resulted as an effect of the same process, denoting the existence of a holarchy of processes and landforms, as they are subordinated one to the other.
