(a) Satellite image and (b) slope map of the Minas Gerais region (Brazil) showing the SCDs. The two SCDs in the black rectangle have been monitored for 2 years (Moretti et al., 2021b; Prinzhofer et al., 2019). The SCDs are located in the small hills between the rivers. The slope is deduced from the Digital Elevation Model (DEM) highlighting also the rivers, the agricultural activity, and the SCDs. Note that SCDs have a rather flat bottom and a positive relief around them. See Appendix B for coordinates.
