Abstract

Geomorphological map of the Rio Spinasanta river basin and illustrative notes (Central-northernSicily). The present paper aims to illustrate the geomorphological map of the Rio Spinasanta riverbasin, in which landforms recognizable on the area are mapped and distinguished according to theresponsible geomorphological process. The Rio Spianasanta river is a tributary of the head sector of the Imera Settentrionale river and is contiguous to the regional water divide that separate the northward and southward flowing Sicilian rivers; the geomorphological map has been produced using assupport a topographic map on scale 1:10,000.The geomorphological map has been carried out by means of different methodologies, namelygeological and geomorphological field surveys, analysis of aerial photos and orthophotos.Moreover,the geomorphological characterization of the area has been supported by the study of the pluviometricconditions and by the analysis of the landforms’ spatial distribution; the latter, which has beencarried out using a GIS software, allowed to evaluate the density of landforms on the classes of the lithology parameter and on the classes of slope angle and aspect.The GIS analysis showed that the combinations of the selected parameters control the intensityof the processes and the spatial distribution of the shaped landforms; this fact led to different landscapes recognizable in the studied area. The landforms mapped in the Rio Spinasanta river basinhave been distinguished according to the modeling processes in: a) landforms shaped by water erosionprocesses; b) landforms produced by gravitational processes.
