Systematic monitoring of an erodible surface at the hillslope scale

Referring to the hills lope evolution due to the wate:r erosion effects, expert.ental measurements in site have been carried out monitoring a part of hillslope s ystematically. In this paper a measure.ent total laser device is described , with i t a calibration and some aodifications on the standard version, too . The collected data have been used as input in suitable a o ftware, obtaining a first evaluat i on of the eroded volume and correlating it wi th the corresponding rainfall characteristics . An important goal at the study is that the hill&lope map, qetting tram the instrume nt used, is a DTM at small scale obtaining a view of surface drain·aqe structures.
