The use of detailed geomorphology for the study of the
Upper Holocene and the application of geoarchaeology and
radiometric datings make it possible to get important results on
the recent stages of valley bottom shaping. The timing of the
aggradation and degradation phases shows the activity of the
processes over the last 8000 years and the decisive influence
of the Holocene evolution on present landscapes.
The reasons for this phase alternation are anthropoclimatic,
as Jordá and Vaudour (1980), Bintliff (1981, 1982),
Gutiérrez and Peña (1998) and Peña (1996), Peña et al. (2000,
2004) recognize in different sectors of the Mediterranean
basin.
The gullies formation and activity from the late Roman
Period has progressed by means of a regressive activity of
the headwaters, although the excavation process has been
temporarily interrupted by new fillings. [--]
