Flooding is the most common natural disaster in Europe and, in terms of economic damage, the most costly one. To plan an effective flood risk management process, a continuous flow of data about discharge and river water level as well as the capability of forecasting in advance their evolution are needed. Satellite data have been widely used in this field, offering a great support to in-situ measurements, which are often available only at a small spatial scale or, in the worst situation, completely missing. Information about soil moisture variation can provide an indirect estimation of discharge, especially useful in poorly gauged areas. In this paper we investigated such a capability by combining information about soil water content variation, in terms of a Polarization Ratio Variation Index (PRVI), recently implemented on Aqua - Advanced Microwave Scanning Radiometer (AMSRE) data, with discharge measurements of the Danube River Basin collected in a few rain gauge stations in Hungary.

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.

L'obiettivo di questo lavoro di tesi è stato quello di studiare la predisposizione a fenomeni di frana nell'area di Collazzone (Umbria) utilizzando un modello distribuito e fisicamente basato, chiamato TRIGRS 2.0 (Baum et al., 2002, 2008). Il lavoro svolto, oltre a definire il set migliore di parametri geotecnici ed idrogeologici di ciascun litotipo, ha permesso di costruire una mappa delle zone con maggior predisposizione al dissesto nell'area di studio.

Northern Fennoscandia bears witness to the Pleistocene glaciation in the form of a series of large faults that have been shown to have ruptured immediately after the retreat of the ice sheet, about 9500 years ago. The largest one, known as the Pärvie fault, consists of a 155 km long linear series of fault scarps forming north-northeast-trending, that stretch west of Kiruna, Lapland. End-glacial intra-plate faults of this extent are very rare in the continental crust and the Pärvie system represents one of the major fault zone structures of this type in the world. Seismological evidence shows that there is still noticeable seismic activity, roughly one event of magnitude 2 per year that can be attributed to the fault. Nevertheless assessing its state of activity is a difficult task due to the extent and remoteness of the area. This study is aimed at the determination of crustal motion around the Pärvie fault zone using the differential inter-ferometric synthetic aperture radar (DInSAR) technique, based on images acquired with the European
Space Agency (ESA) satellites European Remote Sensing (ERS) 1, ERS-2, and the Environmental Satellite (ENVISAT). We present results achieved in terms of deformation of the crystalline bedrock along different sectors of the fault where high levels of coherence were obtained, even from image pairs several years apart. This finding does not exclude deformation in other segments, as observing conditions are not always as favourable in terms of data availability.

By analyzing recent microscopic many-body calculations of few-nucleon systems and complex nuclei performed by different groups in terms of realistic nucleon-nucleon (NN) interactions, it is shown that NN short-range correlations (SRCs) have a universal character, in that the correlation hole that they produce in nuclei appears to be almost A-independent and similar to the correlation hole in the deuteron. The correlation hole creates high-momentum components, missing in a mean-field (MF) description and exhibiting several scaling properties and a peculiar spin-isospin structure. In particular, the momentum distribution of a pair of nucleons in spin-isospin state (ST) = (10), depending upon the pair relative (krel) and center-of-mass (c.m.) (Kc.m.) momenta, as well as upon the angle ? between them, exhibits a remarkable property_ in the region krel?2 fm-1 and Kc.m.?1 fm-1, the relative and c.m. motions are decoupled and the two-nucleon momentum distribution factorizes into the deuteron momentum distribution and an A-dependent momentum distribution describing the c.m. motion of the pair in the medium. The impact of these and other properties of one- and two-nucleon momentum distributions on various nuclear phenomena, on ab initio calculations in terms of low-momentum interactions, as well as on ongoing experimental investigations of SRCs, are briefly commented.

In processes involving small-x partons, like in deep inelastic scattering and in hadronic collisions at high energy, the final state can be expressed in terms of correlators of Wilson lines. We study such high-point correlators evolving according to the JIMWLK equation and we confirm the results of previous numerical and analytic work, by using an independent method, that the solution to the JIMWLK equation can be very well approximated by an appropriate Gaussian wave function. We explore both fixed and running coupling evolution, where in the latter the scale is set according to various prescriptions. As a byproduct, we also numerically confirm to high accuracy the validity of the law governing the behavior of the S-matrix close to the unitarity limit, the Levin-Tuchin formula. We furthermore outline how to calculate correlators with open color indices.

Abstract

The nucleon momentum distribution nA(k) for A=2, 3, 4, 16, and 40 nuclei is systematically analyzed in terms of wave functions resulting from advanced solutions of the nonrelativistic Schrödinger equation, obtained within different many-body approaches based upon different realistic bare nucleon-nucleon (NN) interactions featuring similar short-range repulsion and tensor interactions. Particular attention is paid to the separation of the momentum distributions into the mean-field and short-range correlation (SRC) contributions. It is shown that although at high values of the momentum k different approaches lead to some quantitative differences, these do not hinder the general conclusion that the high-momentum behavior (k?1.5-2 fm-1) of all nuclei considered are very similar, exhibiting the well-known scaling behavior with the mass number A, independently of the used many-body approach and the details of the bare NN interaction. To analyze and understand the frequently addressed question concerning the relationships between the nucleus, nA(k), and the deuteron, nD(k), momentum distributions, the spin (S)-isospin (T) structure of few-nucleon systems and complex nuclei is analyzed in terms of realistic NN interactions and many-body approaches. To this end, the number of NN pairs in a given (ST) state, viz., (ST)=(10), (00), (01), and (11), and the contribution of these states to the nucleon momentum distributions are calculated. It is shown that, apart from the (00) state, which has very small effects, all other spin-isospin states contribute to the momentum distribution in a wide range of momenta. It is shown that for all nuclei considered the momentum distributions in the states T=0 and T=1 exhibit at k?1.5-2 fm-1 very similar behaviors, which represents strong evidence of the A-independent character of SRCs. The ratio nA(k)/nD(k) is analyzed in detail, stressing that in the SRC region it always increases with the momentum and the origin of such an increase is discussed and elucidated. The relationships between the one- and two-body momentum distributions, considered in a previous paper, are discussed and clarified, pointing out the relevant role played by the center-of-mass motion of a correlated pair in the (10) state. Eventually, the values of the the probability of high-momentum components in nuclei and the per nucleon probability a2 of deuteronlike configurations in nuclei are calculated, and the relationship of the present approach with the many-body methods based upon low-momentum effective interactions is briefly discussed.

Color fluctuations in hadron-hadron collisions are responsible for the presence of inelastic diffraction and lead to distinctive differences between the Gribov picture of high energy scattering and the low energy Glauber picture. We find that color fluctuations give a larger contribution to the fluctuations of the number of wounded nucleons than the fluctuations of the number of nucleons at a given impact parameter. The two contributions for the impact parameter averaged fluctuations are comparable. As a result, standard procedures for selecting peripheral (central) collisions lead to selection of configurations in the projectile which interact with smaller (larger) than average strength. We suggest that studies of pA collisions with a hard trigger may allow to observe effects of color fluctuations. (C) 2013 Elsevier B.V. All rights reserved.

Abstract

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.

We are witnessing an increasing concentration of the human population in coastal areas on a global scale. This trend is associated with a growing demand for water, which is satisfied mainly by using local water resources and groundwater in particular. The phenomenon of seawater intrusion is therefore becoming a more serious problem for most coastal aquifers, whose water resources are obviously at risk of being subject to considerable degradation of quality and quantity. The problem is particularly relevant to karst aquifers, prevalent in the entire Mediterranean area and some Italian regions (Friuli, Sardinia, Sicily and Apulia). The purpose of this paper is to describe research that was performed to conceptualise and numerical model a coastal karst aquifer. This research is significant because of the importance of groundwater resources and the high intensity of changes made to well discharge in the absence of scientifically based management when considering effects on quantity and quality. Salento (Apulia) was selected as a case study, and the changes that occurred over 80 years, starting from the beginning of its exploitation, were characterised. Complex acquisitions, together with climatic, hydrological, geological and agricultural data processing, served as the inputs for a numerical model of variable-density flow and transport created using MODFLOW and SEAWAT codes. In particular, groundwater flow under natural conditions was defined using a simulation in a steady-state condition. Through this simulation, it was possible to define the natural resource quantities and the salinity field, or the quality of groundwater that existed when withdrawals were null or negligible (during the 1930s). The transient simulations that we carried out were focused on the twenty years between 1980 and 1999, with the goal of quantifying the effects of the increased discharge used for drinking, industrial and especially irrigation purposes. The validation of the results was accurate due to the availability of high-quality historical piezometric data stemming from the IRPI-BA databases. The overall results demonstrated that the level of groundwater usage from Salento and the increasing discharge trend, due mainly to the global effect of individual water demand, will require a reversal of trends based on management criteria, defined on an aquifer scale and verified with a numerical model, whose potential can be shown by scientific expertise.

In the recent years a change in the predominant morphology of several river environments has taken place, consisting in a reduction of the braided pattern in favor to wandering or straight configurations. This evolution seems to be due, according to the scientific community, to anthropic causes and, in particular, to the alteration of flow regimes as well as the reduction of sediment transport. Braided rivers are characterized by two or more active channels, separated by bars and fluvial islands and normally feature a high morphological dynamism. This dynamism is the result of the interaction among different elements as sediment supply, flow regime and in-channel and perifluvial vegetation. These factors have a fundamental role in the erosion and deposition processes which are the basis of the morphological changes. The aims of this study are the assessment of the short period geomorphic and volumetric changes occurred along a reach of the Tagliamento River and the comparison between the results obtained from LiDAR (Light Detection and Ranging) and TLS (Terrestrial Laser Scanner) data. The Tagliamento river is a natural gravel-bed river located in the NE of Italy, characterized by a relatively low degree of human disturbances. The analyses were carried out considering two different scales (a reach of about 430 ha and a sub-reach of about 25 ha) and were based on two subsequent datasets in order to investigate the shortterm geomorphic changes due to eight significant floods. The surveys were performed using two different datasets derived from LiDAR and TLS technologies and used to analyze the reach and sub-reach respectively. The short-term estimates of geomorphic and volumetric changes were performed using DEMs of Difference (DoD) based on a Fuzzy Inference System. The results have confirmed the high dynamism of the Tagliamento river, estimating a prevalent deposition at reach and a predominant erosion at sub-reach levels. Finally, a comparative qualitative assessment of the output derived from the different data sources was performed, showing little differences between the two survey methods that proved to be both precise and reliable.

Landslide inventory maps are fundamental for assessing landslide susceptibility, hazard, and risk. In tropical
mountainous environments, mapping landslides is difficult as rapid and dense vegetation growth obscures land-
slides soon after their occurrence. Airborne laser scanning (ALS) data have been used to construct the digital ter-
rain model (DTM) under dense vegetation, but its reliability for landslide recognition in the tropics remains
surprisingly unknown. This study evaluates the suitability of ALS for generating an optimal DTM for mapping
landslides in the Cameron Highlands, Malaysia. For the bare-earth extraction, we used hierarchical robust filter-
ing algorithm and a parameterization with three sequential filtering steps. After each filtering step, four interpo-
lations techniques were applied, namely_ (i) the linear prediction derived from the SCOP++ (SCP), (ii) the
inverse distance weighting (IDW), (iii) the natural neighbor (NEN) and (iv) the topo-to-raster (T2R). We
assessed the quality of 12 DTMs in two ways_ (1) with respect to 448 field-measured terrain heights and (2)
based on the interpretability of landslides. The lowest root-mean-square error (RMSE) was 0.89 m across the
landscape using three filtering steps and linear prediction as interpolation method. However, we found that a
less stringent DTM filtering unveiled more diagnostic micro-morphological features, but also retained some of
vegetation. Hence, a combination of filtering steps is required for optimal landslide interpretation, especially in
forested mountainous areas. IDW was favored as the interpolation technique because it combined computational
times more reasonably without adding artifacts to the DTM than T2R and NEN, which performed relatively well
in the first and second filtering steps, respectively. The laser point density and the resulting ground point density
after filtering are key parameters for producing a DTM applicable to landslide identification. The results showed
that the ALS-derived DTMs allowed mapping and classifying landslides beneath equatorial mountainous forests,
leading to a better understanding of hazardous geomorphic problems in tropical regions.

Optical fiber sensors offer unprecedented features, the most unique of which is the ability of monitoring variations of the observed physical field with spatial continuity along the fiber. These distributed optical fiber sensors are based on the scattering processes that originate from the interaction between light and matter. Among the three different scattering processes that may take place in a fiber--namely Rayleigh, Raman and Brillouin scattering, this paper focuses on Rayleigh-based distributed optical fiber sensors. For a given optical frequency, Rayleigh-based sensors exploit the three main properties of light_ intensity, phase and polarization. All these sensing mechanisms are reviewed, along with basic principles, main acquisition techniques and fields of application. Emphasis, however, will be put on polarization-based distributed optical fiber sensors. While they currently represent a niche, they offer promising unique features worth being considered in greater detail.

Glaciers are widely recognized as the best terrestrial indicator of climate change_ nevertheless, changes occurred
since the end of the Little Ice Age (LIA) are often poorly understood. In Italy, glacier front variations in the last
100 years are quite well documented, thanks to the efforts of the Italian Glaciological Committee, which since
1927 coordinates annual surveys on hundreds of glaciers, to measure the position of glacier fronts. However,
changes in time of front position, even being the easiest measure of glacier evolution to be carried out in the field,
only partially describe changes occurred to the glacial masses. Moreover, the last national glacier inventory was
promoted by CGI on occasion of the International Geophysical Year 1957-1958. In the framework of the Alcotra
2007-13 Project n. 56 GlaRiskAlp, we were able to updated the outlines of the glaciers of the provinces of Turin
and Cuneo (Western Italian Alps), and to reconstruct their limits in specific time steps (end of the Little Ice Age -
from geomorphologic analysis, 30s - from IGM cartography, 50s - from the glacier inventory of CGI, 80s from the
glacier inventory WGI). The values of some basic parameters (area, length, width, slope, max and min elevation,
exposure) of the considered glaciers were assessed for the specified time steps. The present contribution is aimed
to provide some statistical analysis of resulting data, taking into account the role played in glacier evolution by
different factors, like latitude, surface, exposition, elevation, together with a description of the climatic context.

Climate changes are more and more attracting the attention of the scientific community because of their direct impacts on geomorphic systems and human activities. A number of studies are currently under way to investigate the evolution of high elevation environments, which proved to be particularly sensitive to climate changes and point to increased in instability in areas of cryosphere occurrence. The here presented research has been developed in the framework of the Alcotra project n.56 "GlaRiskAlp", by CNR-IRPI Torino in collaboration with the DST Torino - GeoSitLab laboratory and is aimed to the validation of an integrated geomatic approach for the evaluation of geomorphologic changes, and related hazards, in glacial and periglacial areas, in the contest of present climatic trends. The proposed approach is based on the coupling of remote sensing techniques and field surveys, in particular digital aerial photogrammetry and satellite imagery, terrestrial scanning LiDAR, and GNSS survey. High-resolution terrestrial LiDAR acquisition, processing and interpretation are used to map periglacial areas in the three dimensions. Laser-generated models offer a visualization tool that, through the comparison of DEMs of different years, allow to detect and to interpret even small geomorphologic changes in time. GNSS-networks are suitable tools for detecting changes over larger surfaces, or horizontal ones. Digital aerial photogrammetry and satellite images can be used to create ortophotos and DTMs of different years, allowing the reconstruction of main geomorphologic changes over the last 50 years. The proposed approach has been applied to case studies of the Piemonte region (Western Italian Alps).

We report on new developments in the application of ambient noise analysis applied to investigate the dynamic response of landslide-prone slopes to seismic shaking, with special attention to the directional resonance phenomena recognised in previous studies. These phenomena can be relevant for seismic slope susceptibility, especially when maximum resonance orientation is close to potential sliding directions. Therefore, the implementation of an effective technique for site response directivity detection is of
general interest. In this regard methods based on the calculation of horizontal-to-vertical noise spectral ratio (HVNR) are promising. The applicability of such methods is investigated in the area of Caramanico Terme (central Italy), where ongoing accelerometer monitoring of slopes with different characteristics offers the possibility of validation of HVNR analysis. The noise measurements, carried out in different times to test the result repeatability, revealed that sites affected by response directivity persistently show major peaks with a common orientation, consistent with the resonance direction inferred from accelerometer data. In some cases such a directivity turned out parallel to maximum slope direction, but this cannot be considered a systematic feature of slope dynamic response. At sites where directivity is absent, the HVNR peaks do not generally show a preferential orientation, with rare exceptions that could be linked to the presence of temporarily active sources of polarised noise. The observed variations of spectral ratio amplitude can be related to temporal changes in site conditions (e.g. groundwater level/soil water content variations affecting P wave velocity and Poisson's ratio of surficial layer), which can hinder the recognition of main resonance frequencies. Therefore, we recommend conducting simultaneous measurements at nearby sites within
the same study area and repeating measurements at different times in order to distinguish significant systematic polarisation caused by site-specific response directivity from polarisation controlled by properties of noise sources. Furthermore, an analysis of persistence in noise recordings of signals with systematic directivity showed that only a portion of recordings contains wave trains having a clear polarisation representative of site directional resonance. Thus a careful selection of signals for HVNR analysis is needed for a correct characterisation of site directional properties.

An important factor in the dynamic equilibrium of the coasts, is human interventions in the
watershed, deltas and coastal zone. These interventions in many cases are intensive and create
serious environmental impacts and dramatic geomorphological changes, related to erosional and
depositional processes, controlling landscape development. Some "dynamic" coastal zones in
Mediterranean Sea, such as that in northern Adriatic coast in Italy and Western Greece coast, are in
a fragile equilibrium. Some segments of these coastal areas, are in a dangerous situation, mainly
because of the anthropogenic influences and especially the construction and operation of large dams
and reservoirs, river diversion projects, motorways and railways, sand and gravel extraction from
river beds, intense construction of coastal defense works and urbanization of large coastal zones,
etc.This paper, attempts to determine the individual human activities that cause the destabilization
of proper geomorphologic evolution of the coastal areas under study, which are located in the
Northern Adriatic coast of the Marche region (Italy) and the Western Greece coast and Epirus
(Greece).
