3. Results
There were several thematic maps elaborated for the Cucuteni-Baiceni Ravine, emphasizing
its dynamics. The morpho-graphic and morpho-metric maps were built on the basis of the
3D scans (Figure 12), which were further used as basis for the spatial yearly analysis of the
ravine. In this case the erosion and accumulation sectors were outlined on the walls of the
ravine or on the bottom of the cut (Figure 13, 14). The measurements included three
consecutive years: 2008, 2009 and 2010.
The Cucuteni Ravine was extremely active during the years 2008-2010, due to the high
frequency of torrential rainfall. The selected site can be regarded as representative for the
whole Moldavian Plateau, as its relief energy is high and the loess deposits of its
subbasement are very friable [16, 58].
Along the gullying processes, the monitoring could include also the gravitational processes,
such as landslides (Figure 15). Due to the loess subbasement and the general deforestation in
the Moldavian Plateau, large tracts of farmlands are subject to large-area landslides [62, 64].
As in the case of gullying, the landslides can be scanned successively, monitoring the
reference points in order to assess the dynamics of the phenomenon. In the present paper,
the case of Holm Hill, near the village of Habasesti (Iasi County), presents a complex
situation due to the presence of an archaeological site (Cucuteni culture). The application of
the 3D scan-based analysis proved to be salutary, as the combined derivates produced using
the point-cloud enabled a successful monitoring of the interest area. The use of 3D graphic
modeling software (3D Studio Max) resulted in the creation of models useful for studying
the topography and planimetry of the prehistoric settlement. All the modeling processes
were based on the available archaeological data and the tridimensional model produced by
scanning (Figure 16).
