A. Digital Elevation Model (DEM) of the study area (location shown in Figure 5) with a 1-m pixel resolution, sourced from the IGN online facility. B to F. Various views of the same alteration corridor identified on the field, which were used to establish a set of morphological criteria (location shown in A). B. Drone oblique view of a linear dry valley not associated with an upstream watershed on the surface. C. On the geological map (Alabouvette et al., 1988), this same feature is interpreted as a fault, although it does not offset beddings. D. On the DEM, it can be described as a linear furrow, and where it intersects with the scarp, it forms a concave notch. E. The slope model highlights the contrast between the steep scarp and the flat bottom of the dry valley. F. In historical aerial photographs, it appears as a grassy meadow, while the steep edges display visible bedrock and bushes.
