Damaging Hydrogeological Events (DHEs) are defined as the occurrence of destructive phenomena (such as landslides and floods) that can cause damage to people and goods during periods of bad weather. These phenomena should be analysed together as they actually occur because the interactions of these phenomena can both amplify the damage and obstruct emergency management.
The occurrence of DHEs depends on the interactions between climatic and geomorphological features_ except for long-term climatic changes, these interactions can usually be considered constant, and for this reason, some areas are systematically affected. However, damage scenarios can change; events that occurred in the past could currently cause different effects depending on the modifications that occurred in the geographical distribution of vulnerable elements.
We analysed a catastrophic DHE that affected a region of southern Italy in 1951 that resulted in 101 victims and 4500 homeless individuals. The probability that a similar event will happen again in the future is assessed using the return period of the triggering rainfall, whereas the different anthropogenic factors are taken into account by means of the population densities at the time of the event and currently. The result is a classification of regional municipalities according to the probability that events such as the one analysed will occur again in the future and the possible effects of this event on the current situation.

The ''Costa Viola'' mountain ridge (southern Calabria), in the sector between
Bagnara Calabra and Scilla, is particularly exposed to geo-hydrological risk conditions.
The study area has repeatedly been affected by slope instability events in the last decades,
mainly related to debris slides, rock falls and debris flows. These types of slope movements
are among the most destructive and dangerous for people and infrastructures, and are
characterized by abrupt onset and extremely rapid movements. Susceptibility evaluations
to shallow landslides have been performed by only focusing on source activation. A
logistic regression approach has been applied to estimating the presence/absence of sources
in terms of probability, on the basis of linear statistical relationships with a set of territorial
variables. An inventory map of 181 sources, obtained from interpretation of air photographs
taken in 1954-1955, has been used as training set, and another map of 81 sources,
extracted from 1990 to 1991 photographs, has been adopted for validation purposes. An
initial set of 12 territorial variables (i.e. lithology, land use, soil sand percentage, elevation,
slope angle, aspect, across-slope and down-slope curvatures, topographic wetness index,
distance to road, distance to fault and index of daily rainfall) has been considered. The
adopted regression procedure consists of the following steps_ (1) parameterization of the
independent variables, (2) sampling, (3) calibration, (4) application and (5) evaluation of
the forecasting capability. The ''best set'' of variables could be identified by iteratively
excluding one variable at a time, and comparing the ROC results. Through a sensitivity
analysis, the role of the considered factors in predisposing shallow slope failures in the
study area has been evaluated. The results obtained for the Costa Viola mountain ridge can
be considered acceptable, as 98.1 % of the cells are correctly classified. According to the
susceptibility map, the village of Scilla and its surroundings fall in the highest susceptibility
class.

Cellular Automata (CA) are discrete and parallel computational models useful for simulating dynamic systems that evolve on the basis on local interactions. Some natural events, such as some types of landslides, fall into this type of phenomena and lend themselves well to be simulated with this approach. This paper describes the latest version of the SCIDDICA CA family models, specifically developed to simulate debris-flows type landslides. The latest model of the family, named SCIDDICA-SS3, inherits all the features of its predecessor, SCIDDICA-SS2, with the addition of a particular strategy to manage momentum. The introduction of the latter permits a better approximation of inertial effects that characterize some rapid debris flows. First simulations attempts of real landslides with SCIDDICA-SS3 have produced quite satisfactory results, comparable with the previous model.

Rainfall amounts, directly responsible for the availability of water resources in a specified area, are closely linked to the climate system. To highlight this relationship, the most important teleconnection indexes, based on the difference in sea level pressure between two geographic areas, tagged centres of climatic action, have been taken into account. In this study, the relationship between winter precipitation, registered in Calabria (Southern Italy), and atmospheric circulation was examined using a correlation analysis with several teleconnection indexes to find useful predictors. In particular, the Spearman's rank correlation test was applied as a measure of the strength of the association between the variables and the Student's t-test was used to evaluate the significance of this analysis. The results show significant and good correlations in particular with the Mediterranean Oscillation (MO), with a correlation coefficient higher than 0.6, with the North Atlantic Oscillation (NAO) and the Scandinavian (SCAND) indexes, with a correlation coefficient between 0.5 and 0.6, and with the East Atlantic West Russia (EA/WR), with a correlation coefficient between 0.4 and 0.5. The correlation is low or not significant for other teleconnection patterns. Moreover, a more detailed investigation was carried out considering five Rainfall Zones of the study area, characterised by different climatic conditions, and the correlations between the above mentioned teleconnection indexes and different Precipitation Categories. The results are interesting because they show that some indexes are closely related to low precipitation while others are linked to severe rainfall.

The contribution presents the database on floods (1981-2010) that is being developed in the framework of HYMEX project and the preliminary results obtained for the NW sector of Mediterranean region. This database contains data on damages and the main hydrometeorological features of each reported event. The study is included in one of the objectives of the Working Group 5, which is a transversal group of the HYMEX project dealing with all the aspects related to societal and ecological impacts of hydrometeorological extremes, as well as their perception and communication processes. One of the main points of the WG5 is the creation of a common database on floods and their societal impact, for the Mediterranean region, as well as its analysis. Although some databases already exist and are frequently consulted, they are mainly focused on "major" catastrophic events. But the Mediterranean region experiences every year a high number of minor flash-floods that, considered in their totality, produce important losses and disruptions of the everyday life. This contribution is focused on North-Eastern Spain, South of Italy and South-East of France and the objective is to include all the floods that have produced damages, although they are not considered as "major" disasters

The "Costa Viola" mountain ridge (Calabria) is exposed to severe geo-hydrological risk conditions, especially in the sector between Bagnara Calabra and Scilla. This sector has repeatedly been affected by slope instability events in the past, mainly related to debris slides, rock falls and debris flows.
An attempt of shallow-landslide susceptibility mapping has been performed for the mentioned coastal sector through a logistic regression (LR) approach. LR is a multivariate
type of analysis that allows estimating the presence/absence of a phenomenon in terms of probability (ranging between 0 and 1), on the basis of linear statistical relationships with a set of independent territorial variables. The adopted LR procedure consists of four steps_ (1) variable parameterization, (2) sampling, (3) fitting, and (4) application. Obtained results can be considered acceptable, as 85.6 % of cells are correctly classified.

Worldwide, most landslides are generally triggered by rainfalls. In this paper, the hydrological model CMSAKe to forecast the timing of activation of slope movements is described. Model calibration can be performed through an iterative algorithm (named "Cluster"): in this way, optimal kernels can be refined from an initial tentative solution. At each iteration, shape and base time of the tentative kernels are optimized by means of a discretized, self-adapting approach; the fitness is computed for all the examined solutions, and new individuals are generated starting from the best kernel obtained at the previous step. The initial shape of the kernel can be selected among a set of standard basic types_ (1) rectangular; (2) decreasing triangular; (3) any other geometrical shape which may sound reasonable on the base of the physical knowledge of the phenomenon. Alternatively, the kernel can be automatically optimized based on antecedent rainfalls with respect to a given date of landslide activation.
In this paper, a first example of application of the model to a large debris slide threatening a village in Northern Calabria is discussed, together with the results of a preliminary sensitivity analysis aimed at investigating the role of the main parameters.

Regional frequency analysis is a useful tool for accurate estimation of precipitation quantiles than at-site frequency analysis, especially in the case of regions with a short rainfall time series. The use of meteorological information, combined with rainfall data analysis, could improve the selection of homogeneous regions. Starting from 1958, 198 meteorological configurations, related to extreme events, have been identified throughout the national territory of Italy. The reanalyzed meteorological data of the 40 Year Re-analysis Archive (ERA-40) of the European Centre for Medium-Range Weather Forecast (ECMWF) have been analyzed to identify homogeneous regions with respect to the Convective Available Potential Energy (CAPE), the Q vector Divergence (QD) and the Vertically Integrated Moisture Flux (VIMF). The latter index appears to be the better candidate for finding regional homogeneity inside areas where high frequency values of CAPE or QD are present. The paper presents an application based on the delimitation of homogeneous regions using climatic indexes for the island of Sicily. By applying the proposed methodology, seven homogeneous areas over Sicily were found. The consistency of the final results has been validated by using a coupled approach based on the Valuation of Floods in Italy procedure (VAPI) and on the heterogeneity test of Hosking and Wallis (Water Resour Res 29_271-281, 1993, 1997).

Abstract
The correct identification of homogeneous areas in regional rainfall frequency analysis is fundamental to ensure the best selection of the probability distribution and the regional model which produce low bias and low root mean square error of quantiles estimation. In an attempt at rainfall spatial homogeneity, the paper explores a new approach that is based on meteo-climatic information. The results are verified ex-post using standard homogeneity tests applied to the annual maximum daily rainfall series. The first step of the proposed procedure selects two different types of homogeneous large regions_ convective macro-regions, which contain high values of the Convective Available Potential Energy index, normally associated with convective rainfall events, and stratiform macro-regions, which are characterized by low values of the Q vector Divergence index, associated with dynamic instability and stratiform precipitation. These macro-regions are identified using Hot Spot Analysis to emphasize clusters of extreme values of the indexes. In the second step, inside each identified macro-region, homogeneous sub-regions are found using kriging interpolation on the mean direction of the Vertically Integrated Moisture Flux. To check the proposed procedure, two detailed examples of homogeneous sub-regions are examined.

The Terme Caronte is located in the territory of Lamezia Terme city in Central Calabria (Southern Italy). This area was one of the test site in the VIGOR project framework. The Terme Caronte test site is characterized by several hot springs showing the presence of a hydrothermal resource with a deep circulation of water along fractures in Mesozoic rocks outcropping on the north portion of the Catanzaro Graben. The site was investigated by a multidisciplinary approach and geologists, geochemists and geophysicists worked defining the geological and hydrogeological deep structure. From geological and hydrogeological point of view, the investigated area is characterized by a small tectonic windows of Mesozoic carbonate rocks (high permeability), outcropping in Terme Caronte district, extruded within transpressional areas. The Calabride Complex (low permeability) is located above the previous one and represents a remnant of the Paleozoic basement, mainly outcropping in the Sila Massif. The terrigenous, evaporitic and carbonate mio-pliocenic sedimentary succession overlies the igneous-metamorphic basement of the Sila Unit and are strongly controlled by NWstrike-slip system, arranged in a right-hand en ´echelon pattern
(Tansi et al., 2007). Several geochemical data were provided and some information on the origin and interactions of the circulating fluids were highlighted. The analysed data showed a normal thermal character of the investigated waters with a normal geothermal gradient (~30°C/km) allowing the existence of low to medium-enthalpy aquifers at a depth of about 1-3 km. The geothermometer for the Caronte system (SO4/F2 Marini et al., 1986) indicates a deep temperature in the range 55-65°C, confirming the low to medium enthalpy of the geothermal system as a whole. Finally, the investigated area misses deep borehole, therefore several deep indirect investigation were analysed. The geophysical work started from the analysis of previous seismic data available from ENI. New eep Geophysical data were acquired in the area_ one Deep Electrical Resistivity Tomography and one MT profile. The DERT and the MT method define a multiscale tomography images of the subsoil, until 4 km. The EM data clearly highlight the contact between different electrical layers which should be associated to the geological formations. Moreover, the main structure associated to the geothermal system and the connection with the hot springs of Terme Caronte are detected, and a first geological and hydrogeological conceptual model was made.

(Southern Italy) at the westernmost edge of the
Catanzaro Graben (CalabrianArc). The area was part
of the VIGOR project framework, aimed at defining
the geothermal potentiality of 8 areas in Southern Italy
through the application of geophysical, geochemical
and geological techniques. The area was investigated
by a multidisciplinary symposium work where
geologists, geochemists and geophysicists meet to
define the geological and hydrogeological deep
structure as well as the hydrothermal resource,
throwing light on the deep circulation of water along
fractures delimiting the north portion of the Catanzaro
Graben. These preliminary results point out Terme
Caronte as an interesting area for low-enthalpy
geothermal exploitation.

Seasonal rainfall amounts, directly responsible for
availability of water resources on a specified area, are strongly
dependent on the climate system. In order to highlight some
features of such dependence, generally circulation indexes
based on the difference in the sea level pressure between two
geographic areas are taken into account. In the present study,
the relationships between winter rainfall series observed in the
Calabria region (southern Italy) and the North Atlantic
Oscillation Index (NAOI) have been analysed. Firstly, a correlation
analysis between precipitation and the NAOI was performed.
Subsequently, the influence of the different phases of
the NAO on the winter precipitation has been detected by a
composite analysis, and by identifying changes in the behaviour
of the probability density functions (gamma distribution)
fitted on monthly rainfall. The results evidence a clear link
existing between the phases of the climatic index and the
amount of winter rainfall.

This work shows a methodological approach for the joint use of geological and geomorphological studies and conventional/innovative monitoring data in densely urbanized areas at landslide risk. The methodology is applied to a test area in the Calabria region (southern Italy) extensively affected by several active landslides involving urban areas. These landslides have been studied and monitored via ground-based techniques for many years. In the study area the comparison and interpretation of DInSAR data with geomorphological studies and inclinometric monitoring has been carried out. The results obtained, thanks to the validation of remote sensed data via ground-truths, provide a further step towards the integrated use of DInSAR data within landslide risk mitigation strategies. © Springer-Verlag Berlin Heidelberg 2013.

La desertificazione è un fenomeno complesso che interessa il suolo e
conduce progressivamente alla perdita della sua capacità produttiva
e funzionale. La Convenzione delle Nazioni Unite per la Lotta alla
Desertificazione (UNCCD) ha definito la desertificazione come "degrado
delle terre aride, semi-aride e sub-umide secche attribuibile a
varie cause, fra le quali le variazioni climatiche e le attività umane". In
questa memoria ne vengono identificate le cause, di origine naturale
e antropica, e vengono indicati i fattori che concorrono a determinare
la predisposizione di un terreno al degrado, attraverso i cosiddetti
"indicatori di desertificazione". Viene riportata la metodologia ESAs
(Environmentally Sensitive Areas), per l'individuazione delle aree sensibili
alla desertificazione, introdotta nell'ambito del progetto MEDALUS,
che si basa sull'elaborazione e interazione di quattro indici di qualità,
relativi ad altrettante categorie di indicatori di desertificazione (clima,
vegetazione, suolo, gestione territoriale). Il rischio di desertificazione
che interessa la Calabria viene, quindi, delineato, con la rassegna
dei risultati dei principali studi condotti su detto territorio. Poiché la
gestione del territorio riveste un ruolo importante nell'instaurazione
e nella progressione del fenomeno della desertificazione, vengono,
infine, indicate alcune azioni e procedure che possono contribuire
all'adattamento dei suoli al fenomeno e alla sua mitigazione.

Calabria is one of the Italian regions mostly affected by
mass movements. The case study of a densely populated neighborhood
(Ianò) located in the central-western sector of Calabria is
presented. The several landslides triggered in February 2010
caused heavy damages to the built area, infrastructures and productions
of this neighborhood, and increased the risk for the
inhabitants. The results obtained through field surveys, photo
interpretation, analyses of rainfall data and of the urban fabric
evolution, historical survey on the reports of the damages caused
by landslides, have enabled to formulate hypotheses on the potential
causes that triggered landslide events and produced severe
consequences on the area. These results have revealed that almost
all landslides of February 2010 are partial reactivations of preexisting
landslide deposits. Moreover, the analyses have indicated
a critical role of cumulative rainfalls over an interval of 15 days.
However, the severe damage framework is explained through an
unplanned urbanization which took place across the years on an
area characterized by a high level of instability per se. Some
buildings have been erected in proximity of or within pre-existing
landslide scarps; in other cases, buildings have been constructed
even inside the landslide bodies.

The stochastic models, developed to simulate long-term hydrological data, can be subdivided in "driven data" models, which reproduce the principal characteristics of the available data series, and "physically
based" models, which schematize the generating mechanism of atmospheric precipitation. The initial step of a "driven data" stochastic model, able to adequately simulate the sequences of wet and dry days,
is the definition of the statistics of the model. In this paper, various statistical models for sequences of no-rain days are firstly presented_ the models are based on an approach which considers the arrival of
rainfall events as a Poisson process, homogenous or not. Moreover, the first results of an application of one of these models to the daily rainfall series registered at the Cosenza rain gauge (Calabria, Southern
Italy) are also shown. In particular, the model applied is a non-homogeneous Poisson model which considers the rainfall as a pulse of random duration.

Genetic algorithms (GAs) are general-purpose search algorithms widely employed in different fields of science and engineering
as both optimization algorithms and scientific models of evolution. Theoretical foundations and the success in
first practical applications have stimulated the study on GAs and new classes of algorithms have been proposed in the
literature. In particular, multiobjective GAs are gaining the attention of the scientific community as powerful search
algorithms for complex problems. Applications of GAs in geomorphology are quite recent. The first applications can be
dated back to the late 1990s, whereas applications of multiobjective versions are still more recent. However, this specific
application field is growing and, even if today underutilized, we anticipate it will become significantly more widespread in
the next few years. This chapter provides an overview of GAs, both in their single- and multiobjective versions, and of their
applications through a few meaningful examples, with the aim of providing both a starting reference point and inspiring
new applications of GAs in geomorphology.

Rainfall amounts, directly responsible for the availability of water resources on a specified area, are closely linked to the climate system. To highlight this relationship, the most important teleconnection indexes, based on the difference in sea level pressure between two geographic areas tagged centres of climatic action, have been taken into account. In this study, the relationship between winter precipitation, registered in Calabria (Southern Italy), and atmospheric circulation was examined using a correlation analysis with several teleconnection indexes to find useful predictors. Specific tests on the results obtained were also applied to evaluate the significance of this analysis. These results show significant and good correlations with the North Atlantic Oscillation (NAO), the East Atlantic West Russia (EA-WR), the Mediterranean Oscillation (MO) and the Scandinavian (SCA) indexes. The correlation is low or not significant for other teleconnection patterns. Moreover, a more detailed investigation was carried out considering five Rainfall Zones of the study area, characterised by different climatic conditions, and the correlations between the above mentioned teleconnection indexes and different Precipitation Categories. The results are interesting because they show some indexes closely related to low precipitation and others to severe rainfall.

A deficit of precipitation has different impacts on the ground water, reservoir storage, soil moisture, snowpack, and streamflow. In this study spatial and temporal patterns of drought in a region of southern Italy (Calabria region) have been analysed. First, the original database was homogenised and the gaps filled in for 129 daily rain gauges for the 1916-2006 period. Then both the short-time (3, 6 and 9 months) and long-time (12 and 24 months) Standardized Precipitation Index (SPI) was estimated to analyse drought especially from the agricultural point of view. A time series analysis was performed with the Mann-Kendall nonparametric test to detect possible trends. A generally negative trend has been detected. Running trend analysis, carried out for long-time SPI, revealed that the previously discussed tendencies were not persistent throughout the series length, but depended on the period examined.
SPI data were interpolated and mapped using a geostatistical approach. Moreover, both the short- and long-time SPI data were analysed by using Factor Kriging Analysis (FKA) to identify and map regionalized factors at different spatial scales from the point of view of SPI.

The NW Mediterranean region experiences every year heavy rainfall and flash floods that occasionally produce catastrophic damages. Less frequent are floods that affect large regions. Although a large number of databases devoted exclusively to floods or considering all kind of natural hazards do exist, usually they only record catastrophic flood events. This paper deals with the new flood database that is being developed within the framework of HYMEX project. Results are focused on four regions representative of the NW sector of Mediterranean Europe_ Catalonia, Spain; the Balearic Islands, Spain; Calabria, Italy; and Languedoc-Roussillon, Midi-Pyr´en´ees and PACA, France. The common available 30-yr period starts in 1981 and ends in 2010. The paper shows the database structure and criteria, the comparison with other flood databases, some statistics on spatial and temporal distribution, and an identification of the most important events. The paper also provides a table that includes the date and affected region of all the catastrophic events identified in the regions of study, in order to make this information available for all audiences.

The paper presents a methodology for relative damage assessment for historical Landslide Events, i.e. periods during which damage caused by rainfall-triggered landslide affected wide areas. The approach requires a minimum amount of data and it is based on the assessment of direct, indirect and intangible damage indices at municipal and regional scale. An application to major events which occurred in Calabria (Italy) highlighted roads as the most vulnerable element, even representing the source of intangible damage for people forced to use alternative roads for their daily activities. Indirect costs seems mainly tied to both displacement of people even for short periods.

This paper proposes an approach for the relative assessment of damage caused along roads
by landslides and floods, which are known as Rainfall-Related Phenomena (RRP). The
proposed approach aims to obtain (a) the trend of phenomena occurrences through the
analysed period, classified in terms of both the type of triggering phenomenon and relative
damage; (b) the location of damage data, allowing the creation of a map of critical points
that must either be monitored during rainfall periods or urgently need defensive work; and
(c) a sketch of the primary circumstances that lead to human injuries along the analysed
road. Finally, an application for a road track in Calabria (Southern Italy) is presented.

been performed according to the HyMex (Hydrological cycle in the Mediterranean Experiment)
framework. HyMex is an international project focused on quantifying the hydrological
cycle in the Mediterranean, analyzing high-impact weather events in the context of
global change. According to their approach, the articles have been sorted in three groups_
(a) those that focus on short-to-medium term effects directly involving people and goods
impacted by the disaster; (b) those that focus on medium-to-long-term socio-economic
effects; and (c) those that focus on short-to-long-term physical and physiological effects on
individuals. The aim is to highlight the approaches used to address this issue in various
scientific fields and thereby to promote the sharing of both data and methodologies and
facilitate the use of an advanced multidisciplinary approach to the NDIA.
