The central Friuli upper plain and the Tagliamento Moraine Amphitheatre (NE Italy) provide good evidence of how the joint analysis of field survey data and surface digital representations (DEM derived maps) can enable more careful geological mapping and a more accurate analysis of landforms and the related forming processes. During the Late Pleistocene and the Holocene, climate fluctuations, active tectonics, and erosional and depositional processes repeatedly affected the study area, leading to a complex evolution in the landscape. The step-by-step reconstruction introduced here is based on recent field data supported by microrelief, shaded relief and 3D map analyses (DEMs). In addition, the advantages of surface digital representations in understanding the evolutions of the study area are considered and discussed in terms of methodology
