| Zusammenfassung |
This contribution shows, through some examples, that the current instability
processes sometimes do not completely correspond (concerning presence,
location, state of activity and/or extent) with those mapped by PTCP
Hydrogeological Hazard Maps, which is the document used by the Province
Administration for its territorial planning.
The differences highlighted are due to different causes. One of them is the
fact that the PTCP Hydrogeological Hazard Maps are practically derived from the
Regional Geological maps in which superficial deposits have secondary
importance, while bedrock and structural-tectonic aspects are given the
highest relevance. Another cause is represented by the very active and
intense geomorphological dynamics of the Apennines which may produce or
reactivate instability conditions.
An important aspect to underline is that the PTCP Hydrogeological Hazard Maps
identify areas with planning constraints, which have effects at a
municipal scale; it does so by starting from a cartographical basis whose
primary aim is not the definition of instability processes and whose
updating is not homogeneous.
Taking into account this aspect, the PTCP Hydrogeological Hazard Maps should be
updated not only on the base of traditional geological mapping, but also
following the criteria of detailed geomorphological mapping which can
precisely define the genesis, dynamics and morphometry of instability
phenomena.
An important consideration, in relation to territorial planning, is that the
PTCP Hydrogeological Hazard Maps should be used just as a "base document",
which requires more necessary detailed deepening at the municipal scale,
accomplished through accurate geomorphological mapping, at least for the
areas that are going to be urbanized.
The geomorphological mapping should also update those elements of the
landscape which could have changed from the official topographic base map.
Detailed geomorphological mapping, possibly undertaken with the methodology
proposed in this paper, could be given in charge also to professional geologists in accordance with standard procedures set in collaboration with
the Provincial Administration. |
