Scenarios induced land use changes and their effects on abiotic and biotic indicators are analysed for a heterogeneous territory in Northern Tuscany.
Results show that under a specific policy scenario the responses are highly variable within a given region depending of the landscape component considered
and that scenarios induced changes result in significant modifications of land use patterns. The changes in crop spatial pattern are clearly
differentiated in three groups of responses depending upon the scenario settings. The spatially explicit approach adopted proved to be necessary to
properly evaluate the impacts of policy scenarios on the environmental services provided by agriculture.

The term "soil erodibility" indicates the aptitude of a soil, based on its properties, to be eroded
by the following processes and exogenous agents_ rainfall, runoff, mass movements and wind.
The concept of erodibility gained in importance during the last 50 years in the field of
soil erosion modelling and applications of soil conservation. However, erodibility is a concept
borrowed from geomorphological literature that was developed and adopted up to the
beginning of the 20th century.
In this context, the concept of erodibility was often used to give a qualitative assessment
of the effectiveness of various forms of erosion caused by exogenous agents such as water, ice
and wind (Davis, 1909). It was used mainly by geologists and geographers for a long time and
related to the processes most effective in the characterization of landform dynamics (Taylor
and Eggleton, 2001; Turkington et al., 2005). It is easy to associate varying rates of erodibility
to compactness of igneous and metamorphic rock masses compared to marls and clay shale,
deeply eroded by gullies. Indeed, the effectiveness of different processes and geomorphic
agents is directly linked to the characteristics of the bedrock in its state of weathering.

Abstract

The Ca' Lita landslide is a large and deep-seated mass movement located in the northern Apennines, about 70 km west of Bologna (Northern Italy). It consists of a composite landslide that affects Cretaceous to Eocene flysch rock masses and chaotic complexes. Many of the sectors making up the landslide have resumed activity between 2002 and 2006, threatening some villages and an important road connecting several key industrial facilities located in the upper watershed. This paper presents the management of the emergency, dealing with the investigation campaigns (geological, geomorphological and LiDAR surveys, borehole drillings, seismic surveys), with the monitoring (in situ instrumentation) and with the design and construction of mitigation measures. The whole process, from landslide reactivation to date, has been modelled on a numerical basis with the finite difference code FLAC 2D, to assess the efficiency of the mitigation system and to propose further countermeasure works in different scenarios.

Persistent Scatterers Interferometry (PSI) and satellite radar imagery can be used to detect very slow displacements (mm-cm per year) of targets (PS) exhibiting coherent radar backscattering properties (mainly man-made structures). Here we present results of the PSI application to the Daunia Apennines, which include many hilltop towns affected by landslides. Examples from the towns Casalnuovo Monterotaro and Pietramontecorvino are used to illustrate that the interpretation of PS data on urbanised slopes can be diffi-cult, because their movements may arise from a variety of processes_ i) volumetric strains within soils, ii) natural or anthropogenic subsidence or uplift, iii) settlement of engineering structures, iv) deterioration of man-made structures, v) extremely slow slope deformations that may or may not lead to failure. Where true landslide movements are detected, they likely regard long-term post-failure displacements involving clay-rich materials.

Abstract

landslides characterized by volumes ...
This study focuses on rock avalanches which are large and very fast
landslides characterized by volumes higher (on average) than two to ten
million cubic metres with velocities of the order of tens of meter per second
and are among the most destructive natural phenomena.
The aim of the research is to increase the knowledge on rock avalanches,
putting at scholars community's disposal a new contribution on some long-
debated questions related to some aspects of their behaviour that have not
been completely understood yet.
In particular the subject of this work is directed to the transport stage of these
phenomena, being the motion characteristics of rock avalanches one of the
most puzzling questions in present days geological debate and none of the
related theories advanced so far has been widely accepted by the scientific
community.
The strangest aspect of the behaviour of fast landslides with a volume of at
least 107 m3 is that they travel much longer than one would expect by normal
Coulomb friction mechanics, which, on the other hand, work rather well for
rockslides of small volumes; this behaviour can be called hypermobility of rock
avalanches.
In the first chapter of this thesis a general introduction to the rock avalanche
theme and related problems is given, followed by the general aims of the
present study and the scheme of the adopted methodology.
The second chapter is dedicated to the review of the international literature on
the long debate on causes, mechanics and characteristics of rock avalanches,
proposed theories for low friction behaviour, stated relations for maximum
runout distance forecast and so on. The aim of this chapter is to give a
general picture of the knowledge state-of-the-art on the matter.
Then an introductory sub-chapter is given on the novel theory of dynamic
fragmentation advanced as an explanation for some geological phenomena
characterized by abnormally low friction, among which the hypermobility of
rock avalanches.
As an example of how dynamic fragmentation can act on rock avalanches and
to give an illustration of the evidence of its effects, three real cases are
presented at the end of this chapter. Two of them regard cases of rock
avalanches, the third refers to a block slide, all three events happened in New
Zealand.
Chapter 3 is on the laboratory part of the present research_ a new concept
rheometer, capable of high pressure and high shear rate, has been designed
and built, in order to obtain an experimental evidence of the effect of the
fragmentation in a shearing sample of rock grains. The main constructive
difficulties, together with the apparatus capabilities and limitations are
9
described. The results of the fragmentation rheologic tests are reported and
commented with special reference to the effects of fragmentation on rock
avalanche behaviour.
The fourth chapter is dedicated to the development of a distinct element
method (DEM) numerical model of the fragmentation rheometer; this model
has been conceived for the purpose of getting a versatile and trustworthy tool
capable to simulate the effects of dynamic fragmentation with reference to
both laboratory rheometric tests (the numerical model does not have the
structural limitations of the real one) and real low friction phenomena. The
numerical model results are presented and commented; pros and cons are
reported as well. The model performances have proved good and worthy of
further developments.
The theses is concluded by a chapter (5) with the final remarks and
conclusions of the whole study, with some future research perspectives
opened by this research.
Two Appendices (A, B) are attached at the end of the Reference listing_
Appendix A contains some more photographs and construction sketches of
the high fragmentation rheometer with an extended set of resulted graphs.
Appendix B contains more information and results of the numerical model of
the rheometer with some examples of PFC (Particle Flow Code) and FISH
(programming language embedded within the code) as it has been used to
build the rheometer model.

Abstract
La disponibilità di strumentazioni per il rilevamento su vaste aree come il LIDAR offre, forse ...
La disponibilità di strumentazioni per il rilevamento su vaste aree come il LIDAR offre, forse per la prima volta, la possibilità di realizzare
modelli Digitali del Terreno (DTM) ad alta risoluzione (2 - 8 punti al metro quadrato) di ampie porzioni di territorio tra cui anche i fiumi.
L'elevata complessità morfologica dei corsi d'acqua e la necessità di rilevare anche le porzioni sommerse, rende tale contesto particolarmente
complesso. L'uso esclusivo del LIDAR non è infatti spesso sufficiente per ottenere un DTM completo e devono quindi essere
ad esso abbinati altri sistemi di rilevamento delle porzioni sommerse. Come per tutte le strumentazioni relativamente recenti, anche in
questo caso non esistono ancora delle modalità di rilevamento standard; esiste dunque forse la necessità, a fronte di progetti di ampia
portata, di provare a definire delle possibili combinazioni di più metodi di rilevamento che si adattino alla differenti situazioni riscontrabili
alla scala, per esempio, del Bacino Padano. L'esperienza condotta dal CNR IRPI di Torino in tale ambito ha permesso sin ora di
riconoscere una possibile relazione tra tipologia di corso d'acqua e modalità di rilevamento. Tale ipotesi, ancora sperimentale, è
comunque il frutto di un'esperienza pluriennale nel campo del rilevamento dei corsi d'acqua con tali tecniche, ma anche dell'impiego di
tale tipologia di dati per lo studio dell'evoluzione morfologica. Generato il DTM ad una specifica maglia (la cui densità di punti idonea a
rappresentare fedelmente le discontinuità morfologiche del territorio è anch'essa oggetto di ricerca) sono infatti possibili diverse applicazioni_
dalle più semplici come l'estrazione di sezioni topografiche alle più complesse, che prevedono la comparazione di modelli digitali
realizzati in tempi diversi sui medesimi tratti di alveo. L'obiettivo di tale comparazione è quello di riconoscere e misurare le variazioni
occorse, attraverso la creazione di una metodologia di gestione e trattamento dei dati che presuppone specifiche conoscenze sia in
campo topografico che geomorfologico. Il processo di comparazione proposto non è infatti un mero esercizio informatico, ma un percorso
basato su una serie di tappe alle quali seguono necessariamente un controllo ed una validazione su basi geomorfologiche attraverso
l'impiego di ortofoto digitali rilevate contestualmente al volo LIDAR. I risultati sin ora raggiunti con questa tecnica sperimentale
riguardano sia la possibilità di valutare in modo continuo le variazioni altimetriche occorse che il calcolo delle variazioni volumetriche
del medesimo periodo. In questo modo è forse possibile affiancare agli studi condotti su sezioni topografiche, un nuovo approccio di
tipo areale (attraverso dei grigliati con passo di 1 m2) che prende in considerazione con continuità l'intero corso d'acqua.
Alla luce dei risultati raggiunti ed in parte esposti, tale metodologia sembra essere in grado di evidenziare le variazioni recenti di un
corso d'acqua con un grado di dettaglio estremamente elevato e di creare un nuovo metodo di studio da abbinare a quelli già comunemente
utilizzati dalla comunità scientifica. L'utilizzo poi di sistemi informativi territoriali, consente anche di creare un'unica base di
dati in cui, tenendo conto delle enormi differenze in termini di precisioni, possono essere inseriti i dati provenienti dalle cartografie storiche,
a fianco delle variazioni volumetriche occorse negli ultimi 3-4 anni; l'obiettivo è quello di per poter alla fine ottenere un quadro il
più possibile esaustivo di tutte le informazioni disponibili, in un'ottica di analisi multidisciplinare del contesto fluviale. L'oggetto della
ricerca non riguarda tuttavia solamente la definizione della metodologia di comparazione dei DTM, ma prende in considerazione anche
le modalità stesse con cui essi vengono generati_ la necessità di affiancare al LIDAR altre strumentazioni finalizzate ai rilevamenti
delle aree sommerse (single beam, multibeam, side scan sonar) ha innescato una profonda riflessione circa la necessità di definire
delle linee giuda che mettano in relazione le tipologie di rilevamento con le caratteristiche morfologiche dei corsi d'acqua analizzati.

This paper shows an investigation on temporal and spatial variability of annual maxima of short duration rainfalls (1, 3, 6, 12 and 24 hours) ranging from 1916 to 2000, selected from the rainfall data set of Calabria (southern Italy). To detect changes in the extreme rainfall series the Mann-Kendall non-parametric test has been used at local scale, considering all the stations involved in the region. Moreover the variability of both parameters and quantiles of empirical intensity-duration-frequency relationships for short duration rainfalls has been explored for different time periods. Finally the monthly distribution of the occurrence process of annual maxima of short duration rainfalls has been statistically analysed.

The following work presents a trend analysis of precipitation observed in Calabria through the Mann-Kendall non-parametric test and a correlation study between rainfalls aggregated at different time scales and two global scale indexes. The results show a general negative trend in precipitation, with the exception of summer season, and links of NAO index with autumn and winter rainfalls, observed in the north-western part of Calabria, and of MO index with winter precipitation, revealing a more uniform distribution throughout the region. Moreover, the NAOI and the MOI, calculated both in autumn and winter periods, have been correlated with precipitation aggregated in enlarged periods, obtaining good correlations for both the indexes with particular reference to the decade 1990-1999. The correlations provide a possible link for water resources
availability when NAOI and MOI are known for the previous periods.

In the past decades, several studies were aimed at defining the relationships between neotectonics and seismicity, and between neotectonics and morphoevolution in Calabria (Southern Italy). More recently, also in cooperation with other colleagues of the CNR-IRPI, our group performed a "combined" analysis of deep-seated morphoevolution, neotectonics and seismicity, and soil-gas radon concentrations in the Crati Graben (Northern Calabria). Similar combined analyses have recently been extended along the NE border of the Sila Massif (again in Northern Calabria), and in the "Stretta di Catanzaro" area (Central Calabria). A more detailed analysis has also been per¬formed in the vicinity of the Acri (CS) village, in the Sila Massif, a study site located on the right flank of the Crati Graben. In the mentioned study areas deep-seated grav¬itational deformations and large-scale landslides, and tectonic structures have been mapped in scale 1/10,000, by means of air-photo interpretation and field examinations. Successively, geological features have been compared with values of soil gas radon concentration, which have been sampled and analysed for the same sectors through geostatistical methods. By cross-analysing the above mentioned geo-environmental items, new insights have been gained into geological hazards related to slope-stability, seismogenesis, and radon emission, and on their mutual relationships. In the present study, the main results of the cited analyses are described, with comparisons of the results obtained in the different study areas. In brief, we found that radon anomalies generally correspond to sectors of severe crustal deformation -i.e. where either neotectonic features or gravitational-tectonic processes, deep-seated gravitational deformations, or large-scale landslides are to be found. Highest radon values match well with active faults, and with macroseismic areas of the main historical earthquakes. On the contrary, large non-diastrophic deformations generally tend to conceal geomorphologic evidence of recent faults, as well as associated Radon anomalies.

Soil slips affect essentially the degraded or weathered covers of soil, and could be particularly
dangerous because of their kinematic mechanism and their spreading over wide areas during rainstorms. The
high incidence of soil slips in an area of Central Calabria (Southern Italy) prompted a research aimed at geotechnical
characterisation of fine-grained soils involved in this kind of instability. This paper illustrates the
geotechnical and the mineralogical characterization carried out on samples coming from three sites representative
of the wider study area, where sedimentary terrain (Plio-Pleistocene) crops out. Classification and direct
shear tests have been conducted on undisturbed specimens and artificially degraded specimens. The results
supply a reference frame of the soils physical-mechanical characteristics. Correlating the geotechnical analysis
with the mineralogical-geochemical investigations allows a wider characterization of the sediment properties.

During the APE-THESEO mission in the Indian Ocean the M-55 stratospheric research aircraft performed a flight over and in the inner core region of the tropical cyclone Davina. Measurements of total water, water vapour, temperature, aerosol backscattering, ozone and trace gases were made and are here discussed in comparison with averages of those quantities acquired during the campaign timeframe.
Temperature anomalies in the TTL, warmer than average in the lower part and colder than averages in the upper part of the TTL were observed; Ozone was strongly reduced compared to its average value, and thick cirrus decks were present up to the cold point, sometimes topped by layer of very dry air. Evidences for meridional transport of trace gases in the stratosphere above the cyclone, and perturbed water distribution in the Tropical Tropopause Layer, are illustrated.
