Abstract

Main droughts recently occurred in Calabria and regional sectors hardest hit have been
found carrying out an historical research. A regional newspaper has been selected as an
information source and articles concerning drought have been selected for the period
among 1980 to 2004. Data inferred from the articles have been organized in a database
in which both hit areas and damaged sectors have been highlighted.
During the study period, the northern sector of Calabria has been hit the hardest. On
this sector additional data have been found in order to better understand the effects of
drought on groundwater availability, particularly on the Sibari Plain, the main costal
plain of Calabria.
For this reason, the climatic trend and the occurrence/duration of exceptionally dry
periods have been investigated, based on long rainfall and temperature time series. In
addition, in order to characterize the effects of droughts periods on the availability of
groundwater, piezometric data, which had been collected from the thirties, have been
compared to 2002 and 2005 in-situ measurements.
At the end a geo-database has been implemented including too climatic and hydrogeological
data.
The analysis shows a remarkably negative rainfall trend and a widespread piezometric
lowering.

Abstract

Disastrous Hydrogeological Events (DHEs) can be defined as the complex of landslide and flood phenomena induced by either heavy or prolonged rainfall. As these latter can simultaneously trigger different types of phenomena, DHEs represent multiplehazard events, which commonly cause huge economic losses and damage in many areas of the Earth. Owing to its geological, geomorphological and climatic characteristics,
Calabria is frequently hit by disastrous hydrogeological events. The ASICal database (Italian acronym for Historically Flooded Areas in CALabria) has recently been implemented, by collecting historical information on landslides and floods occurred during the past centuries, and on related damage (the database is accessible on-line at http_\www.camilab.unical.it). In the present study, historical and hydrologic information concerning DHEs occurred in Northern Calabria (Cosenza province) have been analysed in detail, aiming at exploring the climatic conditions which characterised the main hydrogeological crises. Rainfall data recorded at n.88 rain gauges, uniformly distributed in the study area, have first been statistically analysed, aiming at characterising the most severe rainfall periods. Moreover, the series of the principal damaging events has been reconstructed, and the spatial distribution of damage plotted. Despite it is only a sub-sample of the "complete" history of damage actually suffered in Northern Calabria, this series can be assumed as representative of the most severe damaging events, and it can be compared with the results of the hydrologic analysis. Events have been classified on the base of the severity of damage; rainfall occurred before each event has then been analysed in terms of cumulative values, in order to assess its exceptionality. By considering the results of historical analyses, villages' territories have been classified on the base of frequency of damage. Rainfall periods responsible of principal damaging events have also been typified (in terms of intensity and duration), and their return periods assessed. For each village, the most recurrent phenomena and vulnerated sites/elements have then been recognised. Performed analyses can be helpful in defining scenarios and strategies for risk management in the study area.

Rainfall is a recognized trigger of landslides in different physiographic and climatic
regions world wide. Various investigators have attempted to determine the amount of
precipitation needed to trigger slope failures, and to establish rainfall thresholds for the
initiation of landslides. Determining the amount of rainfall needed to trigger a landslide
is a problem of both scientific and societal interest, and the literature on the topic
is vast. In this work, we present preliminary results of an attempt to systematically collect,
compare, and analyse published rainfall thresholds for the initiation of landslides.
We consider only empirical rainfall thresholds, i.e., thresholds determined through the
analysis of event or historical rainfall conditions that have resulted (or have not resulted)
in slope failures. Information on the empirical rainfall thresholds was obtained
by searching the literature, including international journals, proceedings of regional,
national and international conferences, and national, regional, and local technical and
event reports.We obtained a catalogue of 70 empirical rainfall thresholds for the initiation
of landslides, including global (i.e., worldwide), regional and local thresholds.We
analysed the obtained thresholds based on the type (i.e., shallow or deep-seated) and
the abundance of the landslides (i.e., lower limit, abundant landslides, or catastrophic
thresholds), and the climatic regime for which the thresholds were proposed. For the
analysis, we subdivided the published thresholds in three main categories_ (i) thresholds
that use precipitation measurements obtained for a specific rainfall event, (ii)
thresholds that consider the local rainfall history and temporal pattern, e.g., through
measurements of the antecedent rainfall or soil moisture conditions, and (iii) other
types of rainfall and hydrological thresholds. We further subdivided the thresholds
that use a combination of precipitation measurements obtained for a specific rainfall
event in four sub-categories: (i) intensity - duration (ID) thresholds, (ii) thresholds
based on event (i.e., storm, critical) rainfall, (iii) rainfall event - duration thresholds
(ED), and (iv) rainfall event - intensity (EI) thresholds.We discuss the results obtained,
with emphasis on the advantages and limitations of the different types of thresholds,
and the possible application of the published thresholds in operational landslide warning
systems, at different geographical scales, from the local to the national scale. The
work was supported by RISKAWARE (Risk - Advanced Weather forecast system to
Advise on Risk Events and management), a research project partly financed by the
European Commission through the Interreg IIIB - CADSES programme.

We describe an attempt to establish rainfall intensity - duration (ID) thresholds for
the initiation of landslides in the CADSES area. The CADSES area extends for more
than 2.7 million square kilometres in central, eastern, and southern Europe, and comprises
regions belonging to 19 European countries. To determine the ID thresholds
we compiled a database of rainfall conditions that resulted in slope failures in the
CADSES area and the neighbouring regions. The rainfall and landslide information
was obtained by searching the literature, including international journals, proceedings
of regional, national and international conferences, and national, regional, and local
technical and event reports describing single or multiple rainfall-induced landslides.
We further obtained climatic information for the areas affected by the rainfall and
landslide events, including values for the mean annual precipitation (MAP) and the
average number of rainy-days (RDs), from the Global Climate Dataset compiled by
the Climate Research Unit (CRU) of the East Anglia University. The dataset is available
through the Data Distribution Centre of the Intergovernmental Panel of Climate
Change (IPCC). Our database lists 663 rainfall events that resulted in landslides, and
190 rainfall events that did not result in slope failures. Collectively, the 853 rainfall
events listed in the database cover the period between 1841 and 2002, with the majority
of the events in the period from 1954 to 2002. For each rainfall event in the
database, the available information includes_ (i) the location of the area affected by
the rainfall and the landslide event, (ii) the rainfall conditions that resulted (or did not
result) in slope failures, including the rainfall intensity and duration, the total event
rainfall, and measurements of the antecedent rainfall, (iii) the type and number of the
triggered landslides, (iv) the main rock types cropping out in the region, and (v) climatic
information for the area affected by the rainfall events, including values for the
mean annual precipitation (MAP) and the average number of rainy-days (RDs), and
a classification of climate based on the Köppen climate classification system. We use
the available rainfall and climate information to determine general ID thresholds, and
normalized-ID thresholds. We perform two types of normalization. The first normalization
consists in dividing the rainfall intensity by the MAP. The second normalization
is performed dividing the rainfall intensity by the rainy-day normal (RDN), i.e.,
a climatic index represented by the ratio between the MAP and the average number
of rainy-days (RDs). To determine the ID and normalized-ID thresholds we adopt a
rigorous procedure based on a Bayesian statistical method. The procedure avoids subjectivity
in the determination of the thresholds, a problem that affects several of the
published rainfall thresholds for the initiation of landslides. The work was completed
in the framework of the RISKAWARE project (Risk - AdvancedWeather forecast system
to Advise on Risk Events and management), a research initiative partly financed
by the European Commission through the Interreg IIIB - CADSES programme.
