Cellular Automata (CA) are "a-centric" and parallel space-time discrete dynamical systems, widely utilised in modelling complex natural phenomena. In fact, in spite of their simplicity, they could represent a valid alternative to the classic approach based on partial differential equations in order to simulate phenomena that can be described in terms of local interactions among their constituent parts. SCAVATU-hex is the evolution of the first bi-dimensional CA-based model SCAVATU, developed in order to simulate soil erosion by water. The original cellular space, partitioned in squared cells of uniform size, has been replaced by a regular hexagonal one and the cellular automaton transition function, determining dynamical evolution of the system, has been improved in order to better take into account the real phenomenon. The model has been applied to a real event occurred in the Molise region (Italy) in September-October 2002 using data acquired by a remote automated system, located into the Morgiapietravalle basin. Results of first applications, limited to hydro-dynamic and infiltration processes, and further possible works are presented.

On 15-16 December 1999, heavy rainfall severely
stroke Campania region (southern Italy), triggering numerous
debris flows on the slopes of the San Martino Valle
Caudina-Cervinara area. Soil slips originated within the
weathered volcaniclastic mantle of soil cover overlying the
carbonate skeleton of the massif. Debris slides turned into
fast flowing mixtures of matrix and large blocks, downslope
eroding the soil cover and increasing their original volume.
At the base of the slopes, debris flows impacted on the urban
areas, causing victims and severe destruction (Vittori et al.,
2000).
Starting from a recent study on landslide risk conditions
in Campania, carried out by the Regional Authority (PAI -
Hydrogeological setting plan, in press), an evaluation of the
debris-flow susceptibility has been performed for selected areas
of the above mentioned villages. According to that study,
such zones would be in fact characterised by the highest risk
levels within the administrative boundaries of the same villages
("HR-zones"). Our susceptibility analysis has been
performed by applying SCIDDICA S3-hex - a hexagonal
Cellular Automata model (von Neumann, 1966), specifically
developed for simulating the spatial evolution of debris flows
(Iovine et al., 2002). In order to apply the model to a given
study area, detailed topographic data and a map of the erodable
soil cover overlying the bedrock of the massif must be
provided (as input matrices); moreover, extent and location
of landslide source must also be given.
Real landslides, selected among those triggered on winter
1999, have first been utilised for calibrating SCIDDICA
S3-hex and for defining "optimal" values for parameters.
Calibration has been carried out with a GIS tool, by quantitatively
comparing simulations with actual cases_ optimal
values correspond to best simulations. Through geological
evaluations, source locations of new phenomena have then
been hypothesised within the HR-zones. Initial volume for
these new cases has been estimated by considering the actual
statistics of the 1999 landslides. Finally, by merging the results
of simulations, a deterministic susceptibility zonation of
the considered area has been obtained. In this paper, aiming
at illustrating the potential for debris-flow hazard analyses
of the model SCIDDICA S3-hex , a methodological example
of susceptibility zonation of the Vallicelle HR-zone is presented.

Cellular Automata (CA) represent an alternative approach to differential equations to model and
simulate complex fluid dynamical systems, whose evolution depends on the local interactions of their
constituent parts. A new notion of CA was developed by our research group Empedocles. It permitted to
improve significantly an empirical method for modelling macroscopic phenomena, concerning surface flows.
This approach was applied to lava flows, to debris flows and to pyroclastic flows. This paper presents the CA
extended notion together with the improved empirical method. Examples of simulations are exhibited and
compared with the real events in order to show the method efficiency.

Cellular Automata (CA) represent a formal frame
for dynamical systems, which evolve on the base of local
interactions. Some types of landslide, such as debris flows,
match well this requirement.
The latest hexagonal release (S3-hex) of the deterministic
model SCIDDICA, specifically developed for simulating
debris flows, is described. For CA simulation purposes, landslides
can be viewed as a dynamical system, subdivided into
elementary parts, whose state evolves exclusively as a consequence
of local interactions within a spatial and temporal
discretum. Space is the world of the CA, here constituted
by hexagonal cells. The attributes of each cell ("substates")
describe physical characteristics. For computational reasons,
the natural phenomenon is "decomposed" into a number of
elementary processes, whose proper composition makes up
the "transition function" of the CA. By simultaneously applying
this function to all the cells, the evolution of the phenomenon
can be simulated in terms of modifications of the
substates.
SCIDDICA S3-hex exhibits a great flexibility in modelling
debris flows. With respect to the previous releases of the
model, the mechanism of progressive erosion of the soil
cover has been added to the transition function. Considered
substates are_ altitude; thickness and energy of landslide debris;
depth of erodable soil cover; debris outflows. Considered
elementary processes are_ mobilisation triggering and
effect (T1), debris outflows (I1), update of landslide debris
thickness and energy (I2), and energy loss (T2).
Simulations of real debris flows, occurred in Campania
(Southern Italy) in May 1998 (Sarno) and December 1999
(San Martino V.C. and Cervinara), have been performed for
model calibration purposes; some examples of analysis are
briefly described. Possible applications of the method are_
risk mapping, also based on a statistical approach; evaluating
the effects of mitigation actions (e.g. stream deviations,
topographic alterations, channelling, embankments, bridges,
etc.) on flow development.

Landslides, floods and secondary floods (hereinafter called phenomena) triggered by rainfall and causing extensive damage are reviewed in this paper. Damaging Hydrogeological Events (DHEs) are defined as the occurrence of one or more simultaneous aforementioned phenomena. A method for the characterisation of DHEs based upon
historic data is proposed. The method is aimed at assessing DHE-related hazard in terms of recurrence, severity, damage, and extent of the affected area. Using GIS, the DHEs historical and climatic data collection, the geomorphological and hydrogeological characterisation of the hit areas, the characterisation of induced damage, the evaluation of triggering rainfall return period and critical duration of each DHE were carried out. The approach was applied to a test site in Southern Italy (Calabria) for validation purposes. A database was set up including data from 24 events which have occurred during an 80-year period. The spatial distribution of phenomena was analysed together with the return period of cumulative rainfall. The trend of the occurred phenomena was also compared with the climatic trend. Four main types of Damaging Hydrogeological Events were identified in the study area.

Cellular Automata (CA) can be efficiently applied in the simulation of complex natural processes. They represent an
alternative approach to classical methods based on the resolution of differential equations. In this paper, the general frame and
the latest developments of the Cellular Automata model SCIDDICA (Simulation through Computational Innovative methods
for the Detection of Debris flow path using Interactive Cellular Automata) for simulating debris-flow phenomena are presented.
Landslides characterised by a dominant flow-type (e.g. earth flows, debris flows, debris avalanches) can be considered as
dynamical systems, subdivided into elementary parts that evolve, exclusively, as a consequence of local interactions. In
SCIDDICA, space and time are discrete_ in particular, the space in which the phenomenon evolves is represented by square
cells, whose states describe the considered physical characteristics; time is implicit in the steps of model computation.
The peculiarities of the structure permitted to extend SCIDDICA first release, in order to progressively account for more
complex phenomenological aspects of the considered landslides. In this paper, examples of application of SCIDDICA to three
real landslide events are presented. After briefly describing earlier simulations of the 1992 Tessina (Italy) earth flow and of the
1984 Mt. Ontake (Japan) debris avalanche, first attempts at modelling a debris flow that occurred in 1998 at Sarno (Italy) are
discussed.
The model has been validated through the reconstruction of the initial topographic and geomorphological conditions of a
selected, typical phenomenon (which occurred at Chiappe di SarnoCurti, on May 1998), and by successively comparing the
simulation results with the actually observed debris-flow path.
Even though improvements to the algorithms are still needed, and further testing of parameters on a more representative
sample of phenomena desirable, first simulations of the Curti landslide have demonstrated the reliability of SCIDDICA in the
assessment of debris-flow susceptibility.

Si descrive l'esperienza metodologica relativa alla delimitazione di aree a rischio di inondazione con particolare riferimento alle basi conoscitive tipicamente disponibili per un'area urbanizzata posta in Italia meridionale, specificamente in Calabria.
I corsi d'acqua di questa regione sono in gran parte fiumare, idrosistemi a regime torrentizio, caratterizzati da piene improvvise e trasporto solido cospicuo.
La metodologia applicata ha previsto_ 1) la ricerca storica, estesa su un arco temporale di oltre 400 anni, di notizie di piene e relativi danni; 2) lo studio geomorfologico, basato sulla comparazione di cartografie e foto aeree di diverse epoche; 3) la caratterizzazione statistica delle massime piogge di breve durata incidenti sull'area; 4) il calcolo idraulico delle altezze idriche di deflusso di piene caratterizzate da diversi tempi di ritorno.
Dall'analisi è emerso che, nell'area indagata, il rischio idrogeologico è pericolosamente aumentato nel corso dei secoli. Dal punto di vista metodologico, la procedura proposta si è dimostrata laboriosa, semplice, affidabile, replicabile ma, per quanto attiene al calcolo degli effetti idraulici delle piene, approssimata. Ulteriori rilevanti affinamenti potranno essere conseguiti adottando procedure che si basino su modelli numerici di deflusso e permettano la valutazione degli effetti indotti dai continui interventi umani sul reticolo fluviale e sulle relative aree di pertinenza

he study area is located on the NW boundary of the Sant'Eufemia Plain (Central Cal- abria), where a system of Quaternary normal step faults, oriented WNW and down- throwing toward SE, is to be found. This fault zone characterises, in geo-structural terms, the NW portion of the Catanzaro graben. The Zinnavo fault belongs to the above-mentioned system. As a consequence of its recent activity (Holocene), the dis- tal portion of a notable continental alluvial fan has been displaced (with a maximum apparent separation of ca. 30 m). On the downthrown side of the fault, two smaller and more recent alluvial fans are to be found, thus pointing out at rejuvenation phases of the same tectonic structure. The Zinnavo fault lies within the epicentral zone of the catastrophic earthquake of 1638 a.D., whose MCS intensity has been evaluated as greater than IX_ on that occasion, most of Central Calabria was severely dam- aged. Moreover, along the same tectonic structure, a notable seismic activity is to be recorded. According to the above considerations, the Zinnavo fault can be assumed to be "seismogenetic" and responsible for the high level of seismic risk of the study area, which is densely urbanised and characterised by notable infrastructures (cf. e.g. the Lametia Airport). Geomorphologic and geo-structural investigations have been carried out, through field surveying and air-photo interpretation (from the macro- to the meso- scale). Moreover, surface data have been integrated by means of sub-surface informa- tion, such as_ a) seismic reflection profiles, b) stratigraphic logs, c) helium anomalies. On the basis of the performed analyses, the presence of several high-vulnerability "el- ements" (e.g. the town of Lametia Terme and its airport, the highway and the railway) in the NW sector of the Sant'Eufemia Plain determines high-levels of seismic risk - a fact never evidenced, in the technical literature, before.
