*4.1. Morphometric Analysis*

The study area reaches its maximum altitude on the peak of Corno Piccolo (2655 m a.s.l.) and is characterized by a morphology that gradually slopes down to a minimum of 1030 m a.s.l. in correspondence with Pietracamela Village. Based on the orography of the landscape, the area can be fairly divided into three different sectors: a northern one near Pietracamela village, a central one comprising the Prati di Tivo area, and a southern one corresponding to the northern slope of the Corno Piccolo ridge (Figure 5). The northern sector presents the lowest elevation, ranging approximately from 1100 to 1300 m a.s.l.; the slope values range from 0 to 40◦, with the maximum values detected in correspondence with the N–S-oriented and, secondarily, W–E-oriented drainage lines; the energy of the relief ranges from 250 to 350 m, with the highest values along the Rio San Giacomo. The central sector is characterized by a flat and irregular morphology, featuring elevations ranging from 1300 to 1700 m a.s.l., and a homogeneous slope distribution (values between 5◦ and 20◦); the energy of the relief, on the other side, shows heterogeneous values ranging from 250 m towards the western portion to 400 m towards the eastern one. The southern sector, finally, presents elevations ranging from 1700 up to 2500 m a.s.l.; the slope distribution is dominated by the highest values (between 60◦ and 80◦), with peaks detected in correspondence with the N–S-oriented drainage lines and W–E-oriented steep scarps; the energy of the relief ranges from 500 up to 600 m, with the highest values along the northernescarpmentofCornoPiccolo.
