The spatial distribution of contemporary debris flows of Cāliman Massif has been mapped using photo-interpretation (2004 mission) and field survey. The data was processed and integrated in a GIS (Geographical Information System). We have compared the surfaces of the 70 inventoried debris flows and of their affected basin areas in order to identify the existing correlation between the two parameters. In the Cāliman Massif it seems that the debris flow distribution is controlled by certain factors such as the presence of unconsolidated materials, the steep slopes, the rainfalls, vegetation discontinuities, etc. Despite the fact that the photo-interpretation has some limits, by their combination with field survey we can obtain good results in the mapping process at a regional scale of the remote areas affected by debris flows.
