| Zusammenfassung |
| Since 1990, we have maintained a database of historical information on landslides
and floods in Italy, known as the National Research Council's AVI (Damaged Urban Areas)
archive. The database was originally designed to respond to a request of the Minister of
Civil Protection, and was aimed at helping the regional assessment of landslide and flood
risk in Italy. The database was compiled in 1991-1992 to cover the period 1917 to 1990, and
then updated to cover systematically the period 1917 to 2000, and non-systematically the
periods 1900 to 1916 and 2001 to 2002. The database currently contains information on
more than 32000 landslide events occurred at more than 21000 sites, and on more than
29000 flood events occurred at more than 14000 sites. Independently from the AVI
archive, we have obtained other databases containing information on damage caused by
mass movements and inundations, daily discharge measurements and solid-transport
measurements at selected gauging stations, bibliographical and reference information on
landslides and inundations, and a catalogue of National legislation on hydrological and
geological hazards and risk in Italy. The databases are part of an information system
known as SICI (an Italian acronym for Sistema Informativo sulle Catastrofi Idrogeologiche,
Information System on Hydrological and Geomorphological Catastrophes), which is
currently the largest single repository of historical information on landslides and floods in
Italy. After an outline of the history and evolution of the AVI Project archive, we present
and discuss: (a) the structure of the SICI information system, including the hardware and
software solutions adopted to maintain, manage, update, use and disseminate the
information stored in the various databases, (b) the type and amount of information stored
in each database, including an estimate of their completeness, and (c) examples of recent
applications of the information system, including a web-based GIS system to show the
location of sites historically affected by landslides and floods, and an estimate of
geo-hydrological (i.e. landslide and flood) risk in Italy based on the available historical
information. |
