The knowledge of soil moisture spatial variability is an important issue for hydrolog-ical and climatic studies. This paper investigates the soil moisture spatial pattern obtained from spot measurements carried out in different experimental plots located in small basins of Cen-tral Italy. The near-surface volumetric soil moisture content was measured using a portable time domain reflectometer (TDR) over regular grids whose areas ranging in extension from 9 to 8800 m2. The sampling in each site was periodically repeated in order to investigate the moisture pattern as function of wetness conditions. The statistical properties of the measure-ments and the relation of the statistical parameters with the field-mean soil moisture content were analyzed. The results states that the probability distribution can be assumed normal for soil moisture in flat areas and for normalized soil moisture in gentle slope areas. A general decreasing trend of variance with increasing mean moisture content was observed. Moreover, considering the relationship between the field-mean water content and the coefficient of var-iation an optimal measurements number ranging from 15 to 35, in the worse case, was found for the study areas. The higher number was required for the site with more significant relief. These results were also confirmed through the geostatistical analysis and the correlation with the topographical attributes. Specifically, the correlation lengths were found increasing with the mean areal slope and the mean drainage direction and ranging between 10 and 15 m. This is corroborated through geostatistical analysis showing that the natural logarithm of the specific
upslope area was the best spatial predictor for near-surface soil moisture when the water vol-ume in the soil is higher. On this basis, the surface and subsurface lateral redistribution of water can be surmised fundamental in spatial organization of soil moisture.

The Sauris reservoir is a hydroelectric basin closed downstream by a 136 m high, double arc concrete dam. The dam is firmly anchored to a consistent rock (Dolomia dello Schlern), but the Lower Triassic clayey formations, cropping out especially in the lower part of the slopes, have made the whole catchment basin increasingly prone to landslides. In recent years, the "La Maina landslide" has opened up several joints over a surface of about 100 000 m2, displacing about 1 500 000 m3 of material. Particular attention is now being given to the evolution of the instability area, as the reservoir is located at the foot of the landslide. Under the commission of the Regional Authority for Civil Protection a numerical modelling simulation in a pseudo-time condition of the slope was developed, in order to understand the risk for transport infrastructures, for some houses and for the reservoir and to take urgent mesaures to stabilize the slope. A monitoring system consisting of four inclinometers, three wire extensometers and ten GPS bench-mark pillars was immediately set up to check on surface and deep displacements. The data collected and the geological and geomorphological evidences was used to carry out a numerical simulation. The reliability of the results was checked by comparing the model with the morphological evidence of the movement. The mitigation measures were designed and realised following the indications provided by the model.

Lo studio della variabilità spaziale delle precipitazioni, soprattutto in aree caratterizzate da un'orografia accentuata come quella calabrese, è importante per la valutazione della disponibilità di risorse idriche e delle conseguenze sull'uso del suolo e sulle attività economiche. La geostatistica è un utile strumento per la caratterizzazione della variabilità e dell'interpolazione spaziale. Oltre alla variabilità spaziale quella temporale è un valido strumento nello studio dei cambiamenti climatici. Lo scopo di questo studio è quello di contribuire ad una migliore conoscenza della variabilità spaziale e temporale delle precipitazioni in Calabria attraverso_ (a) la quantificazione della struttura spaziale delle precipitazioni medie annue e della loro interpolazione spaziale con i metodi della geostatistica; (b) la valutazione della persistenza temporale delle precipitazioni medie annue tramite la differenza media standardizzata calcolata sulle medie decennali. L'analisi effettuata ha permesso di quantificare la variabilità spaziale delle precipitazioni medie annue e di identificare un trend negativo dei valori medi decennali delle precipitazioni con un cambiamento nella loro distribuzione spaziale.

Persistent Scatterers Interferometry (PSI) techniques allow to detect and monitor millimetric displacements occurring on selected ...
Persistent Scatterers Interferometry (PSI) techniques allow to detect and monitor millimetric displacements occurring on selected point targets exhibiting coherent radar backscattering properties (mainly buildings and other man-made structures). The technique is sensitive to the number and spatial distribution of point targets and, therefore, particular care must be used when dealing with scarcely-urbanized areas.
In the present work we apply the SPINUA (Stable Point INterferometry over Un-urbanised Areas) PSI processing technique [1] to the Daunia region located in Southern Apennines, Italy. This region includes several isolated small hill-top towns affected by slope instability problems. We selected for the analysis an area of 25×25 km2, enclosing 10 urban centres. A dataset of both descending (84) and ascending (51) ERS-1/2 acquisitions has been processed to allow investigation of slopes with a wide distribution of facing directions. In order to ensure an adequate distribution of coherent points for a reliable estimation of the atmospheric signal, the analysis has been limited to small image windows which enclose urban areas. This strategy, which has been also applied to other similar test sites [2], is justified by the fact that landslides with the highest socio-economic impact are those involving the urban centres.
The density of the detected stable targets resulted suitable for 8 of the 10 investigated town areas, with a very good coverage of urban structures in 5 cases. The remaining 2 towns show a low number of PS, making difficult the detection of displacements. These outcomes could depend on the geometrical distribution of the coherent structures potentially corresponding to the PS. Although in several cases the displacement fields show clear evidence of moving objects located on urban and peri-urban areas, local knowledge of the investigated area and in situ inspections are required in order to interpret correctly the significance of PS motion data and to identify the main mechanism of the detected deformations.

We present two case studies regarding the application of Synthetic Aperture Radar (SAR) Persistent Scatterers Interferometry
(PSI) techniques to landslide-prone slopes situated in the municipal territories of Caramanico Terme and Volturino (Italy). The
analysis of satellite SAR data with PSI techniques poses often problems on sites where, due to the scarcity of human artefacts and the
presence of vegetation cover, density of coherent points (PS) is low (b10 per km2). Moreover, the steep and rough topography typical
of landslide-prone areas hamper the interferometric pre-processing, making more difficult the joint estimation of displacements and of
DEM errors. Under these conditions the significance of temporal interferometric phase trends can be uncertain and conservative
assumptions, necessary to ensure low false detection probabilities, need to be coupled with innovative processing strategies to
increase the detection efficiency of PS objects. Here, the SPINUA (Stable Point Interferometry over Un-urbanised Areas) processing
technique is applied together with an alternative PS Candidate (PSC) selection procedure based on the use of pixels classified as urban.
The cases of Caramanico and Volturino are representative, respectively, of harsh and favourable conditions for PSI applications. The
results from Caramanico show clusters of PS exhibiting similar line-of-sight (LOS) deformation behaviour in the period 19952000. The
locations ofmoving PS often coincidewith distressed buildings and appear consistent with the areal distribution of recent and past landslide
activity. The temporal displacement trends, however, are characterised by very low annual average velocities (from 3 to 7 mm/y) and it is
uncertain to what extent the PS data reflect true slope movements, local deformations (e.g. settlement of engineering structures) or both.
Thanks to the more favourable conditions, the application of the standard SPINUA approach in the Volturino area was sufficient to
obtain suitable densities of PS, as well as spatially and temporally consistent displacement results for a period 19922000. In
particular, a group of moving PS was identified in a peri-urban area, known for the past and recent slope stability problems. The slowly
moving PS (from 3 to 5 mm/y) fall in a location that, unlike the remaining part of the town, is characterised by the presence of many
distressed buildings and structures. Although the site information confirms the reliability of PS data, in the absence of ground
monitoring and detailed records of landslide movements, it is difficult to identify the main mechanism of the detected deformations. In
general, in geologically and topographically complex urban/peri-urban settings, the significance of very low-velocity PSI surface
displacements should always be considered together with in situ geotechnical controls and ground monitoring data.

Abstract

Calabria is the southernmost part of the Italian peninsula. Its climate is Mediterranean with
arid conditions along spots of the Ionian coast and montane modifications. Its morphology is dominateci
by tectonics, with mountains and valleys corresponding to uplifted blocks and intervening grabens, respectively.
Most of the streams in Calabria are fiumara torrents with very steep slopes and riverbeds; the latter
are usually flat, braided and wide, covered with coarse-grained alluvium. Alternating predominance of
debris production by mass-movement and erosion on slopes, and of the transport capacity of fiumara torrents,
gives rise to their typical strong aggradation/degradation cycles which may last from years to centuries.
Factors of fiumara generation are essentially four_ geodynamics, lithology of the drainage basins, climate
and human pressure. Geodynamics, in particular tectonic uplift, is the generator of relief energy
keeping the morphogenetic processes at a high magnitude and in a relatively stationary condition since
the end of the Early Quaternary. Occasionally, earthquakes act as landslide trigger events. Widespread
diffusion of lithic rocks is the origin of coarse-grained alluvium. Aggressive clima te with intense storms
and high variability is the cause of widespread mass-movement reactivation. Human pressure acting either
directly on riverbed stocks, or indirectly on climate changes, may strongly influence the degradation/
aggradation regime of fiumara torrents that, in turn, is reflected in the beach aggradation/degradation
regime.
Hypsometric curves of fiumara basins are predominantly concave, even though departures from this
form are numerous; the average value of the hypsometric integrai, however, indicates equilibrium conditions.
This may explain why riverbeds of fiumara, though presenting aggradation/degradation cycles, are
essentially stationary forms since a t least the Holocene. The drainage network is characterised by a high
number of anomalous branches. The hydraulic regime of fiumara is typically torrential as regards surface
runoff, but a relatively regular ground-water flux in the alluvial bed is a common feature.
In comparison to other Mediterranean ephemeral streams, Calabrian fiumara streams are characterised
by an extremely high rate of mass-movement on the slopes, by a high solid/liquid discharge average
rate, by the scarcity of evidences of discontinuous gullying to accommodate for stages of reduction in
solid/liquid discharge rate, and by the neat prevalence of fiumara torrents on the Ionian side of Calabria,
due to the geologica! and climatic peculiarities of this side of the peninsula ..

Abstract
The standard application of multi-temporal, Persistent Scatterer (PS) synthetic aperture radar differential interferometry (DInSAR) techniques ...
The standard application of multi-temporal, Persistent Scatterer (PS) synthetic aperture radar differential interferometry (DInSAR) techniques to the Caramanico area posed considerable problems linked to the low density of PS [1]. The application of an optimised PSI approach [2], together with an alternative, classification-based PS candidate detection method [3,4], allowed obtaining sets of PS with more stable targets and higher average inter-image coherence, and thus a lower probability of detecting false displacements. Although the harsh conditions encountered in Caramanico confer some uncertainty to the exact significance of the SAR target displacement results, the reliability of the SAR interferometry results is supported by the presence of PS groups exibiting similar deformation behaviour. Furthermore, the locations of the groups of moving PS appear consistent with the areal distribution of recent and past landslide activity in Caramanico. The moving PS also tend to coincide with places including distressed buildings and structures. In general, however, some variability in the local ground surface displacement patterns is to be expected in manmodified, geologically and geomorphologically complex hillslope settings like that of Caramanico. The variability may be related not only to landslide processes but also to other more or less local ground deformation phenomena such as subsidence (whether natural or man-made), settlement of engineering structures, volumetric changes of geological materials. It follows that in situ data and monitoring controls will usually be needed to discriminate the exact cause of very slow ground surface deformations detected on the basis of PS analysis.

A landslide affecting two small villages located on the Northwestern Italian Apennines has been investigated since the year 2000 through the use of different equipment.
A complex monitoring system has been installed in the area. The system includes several inclinometers, piezometers and a raingauge. An Automatic Inclinometric System (AIS) has been also installed that automatically performs measurements, twice a day, along the entire length of a pipe that is 45m deep. This monitoring system has been set up to identify a methodology that allowed to deal with landslides, trying to predict their behaviour beforehand for warning purposes. Previous researches carried out in the same area for a period of about 7 months, in the year 2000, have allowed to identify a correlation between deep slope movements and rainfalls. In particular, it has been possible to determine the time lag needed for a rainfall peak to produce a corresponding peak of the landslide movements; this time lag was of 9 days. This result was possible because the AIS allows toobtain, as mentioned, daily inclinometric measurements that can be correlated with the recorded rainfalls. In the present report we have extended the analysis of the correlation between deep slope movements and rainfalls to a greater period of observation (2 years) to verify over this period the consistency of the time lag mentioned above. The time lag previously found has been confirmed. We have also examined the possibility to extend to the entire landslide body the correlation that has been found locally, analyzing the results of the remaining inclinometric tubes with traditional reading installed on the landslide and comparing them with the results of the AIS. The output of the tubes equipped with piezometric cells has also been analyzed. The relations existing among rainfalls, ground water level oscillations and the related slope movements have been explored.

Floods are a very common natural process in Italy. In the 20-year period from 1980 to 2000 the State set aside 7.400 million euro for flood damage. or roughly
one million euro per day. With this study we developed a flood damage estimation model which land administration bodies and insurance companies could find useful
in the management of flood-related damage data. The model simulates event scenarios and evaluates expected economie losses. Potential
economic loss assessment implics knowledge of the event exposed asset values and the degree of damage. Following a widely shared simplifying assumption.
flood water level was taken as the only factor indicating event magnitude. The model incorporates the following steps_ a) event description_ definition of flood parameters
(flooded area and water level), utilizing real-time measurements or data from event simulation with a hydraulic model; b) asset damage and identification oft he affected popu!ation;
c) evaluation of the degree of damage as a function of event magnitude; d) attribution of an economic value to different exposed assets; e) quantification of economie loss by multiplying economic losses and damage severity.
Thc method could be used either as a forecasting tool to define event scenarios or for "real-time" damage assessment after a catastrophe. The approach is suitable primarily to large-arca damagc assessment
but could also be appropriate for landuse planning. civil protection and risk mitigation.

The quality and quantity of groundwater flow is very important for hydrological and ecological equilibrium where groundwater discharge into the sea and transitional environments is higher than river discharge. This is the case of the Murgia Plateau (Murgia) and of the Salentine Peninsula (Salento), located in the Apulian Region, southeastern Italy, selected as the study area for this research. Data collected by many surveys in which wells and coastal springs were sampled are discussed. Many physical, chemical and bacteriological
parameters are considered. A quality classification partially based on Italian and European laws is defined to classify and compare groundwater quality. The groundwater pollution is quite absent only in the inner areas of the Murgia and the Salento, constituting portions of the recharge zone. Groundwater flowing from these areas to the sea is progressively polluted. This pollution load discharges into the sea or into wetlands and lagoons, constituting a huge hazard for the ecological equilibrium of valuable sites.

The autumn of 2004 was particularly wet in Umbria, with cumulative rainfall in the period from October to December exceeding 600 mm. On 4-6 December and on 2527 December 2004, two storms hit the Umbria Region producing numerous landslides, which were abundant near the town of Orvieto where they affected volcanic deposits and marine sediments. In this work, we document the type and abundance of the rainfall-induced landslides in the Orvieto area, in south-western Umbria, we study the rainfall conditions that triggered the landslides, including the timing of the slope failures, we determine the geotechnical properties of the failed volcanic materials, and we discuss the type and extent of damage produced by the landslides. We then use the recent event landslide information to test a geomorphological assessment of landslide hazards and risk prepared for the village of Sugano, in the Orvieto area. Based on the results of the test, we update the existing landslide hazards and risk scenario for extremely rapid landslides, mostly rock falls, and we introduce a new landslide scenario for rapid and very rapid landslides, including soil slides, debris flows and debris avalanches.

We describe daily rainfall occurrence at five gauge stations in southern Calabria Ionica during the October-April wet season 1971-2000. A hidden Markov process is then used to model such a phenomenon.

We present the results of the application of a recently proposed model to determine landslide hazard. The model predicts where landslides will occur, how frequently they will occur, and how large they will be in a given area. For the Collazzone area, in the central Italian Apennines, we prepared a multi-temporal inventory map through the interpretation of multiple sets of aerial hotographs taken between 1941 and 1997 and field surveys conducted in the period between 1998 and 2004. We then partitioned the 79 square kilometres study area into 894 slope units, and obtained the probability of spatial occurrence of landslides by
discriminant analysis of thematic variables, including morphology, lithology, structure and land use. For each slope unit, we computed the expected landslide recurrence by dividing the total number of landslide events inventoried in the terrain unit by the time span of the investigated period. Assuming landslide recurrence was constant, and adopting a Poisson probability model, we determined the exceedance probability of having one or more landslides in each slope unit, for different periods. We obtained the probability of landslide size, a proxy for landslide magnitude, by analysing the frequency-area statistics of landslides, obtained from the multi-temporal inventory map. Lastly, assuming independence, we determined landslide hazard for each slope unit
as the joint probability of landslide size, of landslide temporal occurrence, and of landslide spatial occurrence.
