Differential Synthetic Aperture Radar Interferometry (DInSAR) represents a well-established remote sensing technique for the investigation of ground deformation phenomena. Among the DInSAR techniques, the Small BAseline Subset (SBAS) approach exploits ground surface at two mapping scales, low and high resolution, and allows the detection and monitoring of local deformation processes that may affect single buildings or man-made structures in urban areas. This work investigates the capability improvement of the SBAS-DInSAR technique to analyse deformation processes in urban areas by exploiting SAR data acquired by the Cosmo-SkyMed (CSM) constellation in comparison with the results obtained from data of first generation ERS/ENVISAT radar systems of he European Space Agency. In particular, we extracted mean deformation velocity maps as seen by the three different radar systems and, for each coherent pixel, we retrieved the corresponding displacement time series. Our analysis was focused on the Torrino area where independent studies had already revealed significant deformation signals testified by the serious damages on many buildings in the area. Moreover, in order to understand the causes of the CSM observed displacement rates, reaching few cm per year, we also performed a comparative analysis between DInSAR products and independent information derived from electrical resistivity tomography data and geological maps.

La memoria presenta un'analisi delle potenzialità di sensori satellitari a bassa
risoluzione spaziale per la stima di variabili idrologiche, quali la portata e il
contenuto d'acqua, e per la calibrazione della modellistica idraulica attraverso la
simulazione delle aree allagate. Per quanto riguarda la portata, si è ottenuta una
buona correlazione tra i dati elaborati del radiometro MODIS e la velocità media
per due sezioni del Fiume Tevere che ha permesso quindi di valutare la potenzialità
di tali dati anche per la determinazione della scala di deflusso. L'assimilazione dei
dati di contenuto d'acqua stimati dallo scatterometro a microonde ASCAT nella
modellistica idrologica ha fornito un effettivo miglioramento per la previsione delle
portate. Infine, l'uso di immagini SAR si è rivelato un grande supporto per la
calibrazione della scabrezza nel modello idraulico applicato per un piccolo bacino
dell'Alto Medio Tevere. I risultati sono, quindi, promettenti per l'effettivo utilizzo dei
dati satellitari in condizioni operative.

Abstract

The velocity field in a river flow cross-sectional area can be determined by applying entropy as done in 1978 by Chiu, who developed a two-dimensional model of flow velocity based on the knowledge of maximum velocity, umax, and the dimensionless entropic parameter, characteristic of the river site. This is appealing in the context of discharge monitoring, particularly for high floods, considering that umax occurs in the upper portion of flow area and can be easily sampled, unlike velocity in the lower portion of flow area. The simplified form of Chiu's entropy-based velocity model, proposed in 2004 by Moramarco et al., has been found to be reasonably accurate for determining mean flow velocity along each vertical sampled in the flow area, but no uncertainty analysis has been reported for this simplified entropy-based velocity model. This study, therefore, performed uncertainty analysis of the simplified model following a procedure proposed by Misirli et al. in 2003. The flow velocity measurements at the Rosciano River section along the Chiascio River, central Italy, carried out for a period spanning 20 years were used for this purpose. Results showed that the simplified entropy velocity model was able to provide satisfactory estimates of velocity profiles in the whole flow area and the 95% confidence bands for the computed estimated mean vertical velocity were quite representative of observed values. In addition, using these 95% confidence bands, it was possible to have an indication of the uncertainty in the determination of mean cross-sectional flow velocity as well.

A real-time Flood Forecasting and Warning System (FFWS) is the main nonstructural
measure for reducing risk in flood-prone areas. A model able to provide
reliable stage and discharge forecasts is one of the fundamental FFWS components.
In this context, a simple model for real-time flood forecasting is proposed for river
reaches where significant lateral inflow contributions occur. The model, based on the
real-time Rating Curve Model, allows predicting the discharge hydrograph at a river
site where only the stage is monitored when the flow is known at an upstream
section. The model performance was found satisfactory for two river reaches of the
Tiber river basin, central Italy, characterized by different intermediate drainage areas.
Finally, the forecast uncertainty estimate is addressed through 95% confidence
interval based on the statistical properties of the forecast lateral inflow.

This study investigates the potential of the low-resolution images (150m) derived by the Advanced SyntheticAperture Radar onboard
the ENVISAT satellite to calibrate a hydraulicmodel coupled with a semidistributed hydrologicmodel applied to a subcatchment of the
upper-middle TiberRiver,Genna basin (<100 km²), in central Italy,wherein a flood event occurred on 28 November 2010 causing high
damages. Specifically for thisflood event, anAdvanced SyntheticAperture Radar image is available for the peak region of the discharge
hydrograph. Different image processing techniques are used for the assessment of the flooded areas by using both a single image and a
change detection image based on an additional (dry) reference image. The satellite-derived flooded areas are adopted for the calibration
of the channel and floodplain Manning's roughness coefficients of a 'quasi-two-dimensional' hydraulic model applied to the study
basin, which allows to distinguish the main channel from the floodplain. The inflows for the hydraulic model corresponding to each
tributary of the main channel are determined by a semidistributed hydrologic model calibrated by using a set of historical flood events.
The hydraulic model calibration is also carried out by using the same set of historical flood events. For the event of November
2010, the modelled discharge and water level hydrographs obtained with the two sets of Manning roughness (via satellite and
historical calibration) are compared with in situ observations at the outlet of the basin.
This application on a small catchment contributes to strengthen the value of remote sensing data confirming the potential of
synthetic aperture radar imagery to reduce uncertainties in hydraulic modelling calibration.

Rainfall scenarios are of considerable interest for design flood and flood risk analysis. To this end, the stochastic
generation of continuous rainfall sequences is often coupled with the continuous hydrological
modelling. In this context, the spatial and the temporal rainfall variability represents a significant issue,
especially for basins in which the rainfall field cannot be approximated through the use of a single
station. Therefore, methodologies for the spatially and temporally correlated rainfall generation are welcome.
An example of such a methodology is the well-established Spatial-Temporal Neyman-Scott Rectangular
Pulse (STNSRP), a modification of the single-site Neyman-Scott Rectangular Pulse (NSRP)
approach, designed to incorporate specific features to reproduce the rainfall spatial cross-correlation.
In order to provide a simple alternative to the STNSRP, a new method of generating synthetic rainfall
time series with pre-set spatial-temporal correlation is proposed herein. This approach relies on the single-
site NSRP model, which is used to generate synthetic hourly independent rainfall time series at each
rain gauge station with the required temporal autocorrelation (and several other appropriately selected
statistics). The rank correlation method of Iman and Conover (IC) is then applied to these synthetic rainfall
time series in order to introduce the same spatial cross-correlation that exists between the observed
time series. This combination of the NSRP model with the IC method consents the reproduction of the
observed spatial-temporal variability of a rainfall field.
In order to verify the proposed procedure, four sub-basins of the Upper Tiber River basin are investigated
whose basin areas range from 165 km² to 2040 km². Results show that the procedure is able to preserve
both the rainfall temporal autocorrelation at single site and the rainfall spatial cross-correlation at
basin scale, and its performance is comparable with that of the STNSRP model for rainfall field generation.
Given its simple formal structure (based on well established methods_ i.e. NSRP and IC), we believe that
the proposed approach can be conveniently utilized to generate spatially and temporally correlated rainfall
scenarios.

Abstract

Water erosion is one of the major causes of soil loss, and consequently one of the most important causes of economic
loss for a region. Water erosion includes sheet, rill, gully and channel erosion, and contributes significantly
to sediment delivery to permanent drainage network. Soil erosion is due to detachment and transport of soil particles
by the direct action of raindrops and runoff water. When runoff concentrates soil erosion may locally peak
with the formation of rills and gully channels. Direct measurements of soil loss during episodes of ephemeral gully
formation are rare. Generally, gully erosion is measured by an a posteriori field survey, through the assessment of
the eroded volumes. Hence, spotting gullies and large rills is extremely important to evaluate erosion on a slope.
Field survey tends to underestimate channel erosion. Several studies attempted to determine length and depth of
rills and gullies using stereoscopic aerial photographs in small areas. Very High Resolution (VHR) satellite images
can allow mapping these features over larger areas. This work exploits the use of VHR stereoscopic satellite images
in the Collazzone study area (Central Italy): (i) to identify and map erosion forms, (ii) to extract the relative
channel morphometric parameters (i.e. length, width and depth), and hence (iii) to evaluate the eroded volumes.
We estimated the power law fitting parameters correlating length and channel volumes, and we compared them to
those in the literature estimated from field survey data. Finally we analyzed the density distribution of gully and rill
channel length. Results show that rill-gully segments (a segment being the part of channel between two successive
tributaries) follow an exponential distribution. This result can be used to simulate eroding network formations and
hence to estimate their impact on a slope. Such a characteristic distribution complements the existing set of relationships
which includes relations_ (i) between the angles among tributaries and main channel and the local slope
gradients, (ii) between channel width, channel bed roughness and formative peak discharge, and (iii) topographical
thresholds for rill and gully formation.

La Regione Umbria con DGR n. 1175 del 01/10/2012 ha costituito un gruppo di lavoro ...
La Regione Umbria con DGR n. 1175 del 01/10/2012 ha costituito un gruppo di lavoro finalizzato alla valutazione degli effetti degli incendi boschivi sulla suscettibilità da frana occorsi lungo la SS 3 "Flaminia" nei pressi di Molinaccio (TR) nei giorni 20-23 luglio 2012 e lungo la SP 418 "Spoletina" in località Acquasparta il 19 luglio 2012. Il dott. Dino Torri e il dott. Mauro Rossi dell'Istituto di Ricerca per la Protezione Idrogeologica del Consiglio Nazionale delle Ricerche (IRPI CNR) sono stati individuati dalla delibera quali esperti di rischio idrogeologico da frana.
In tale rapporto sono riportati i risultati dell'analisi preliminare delle variazioni della propensione al dissesto delle zone interessate dagli incendi oggetto di studio.
Frane e processi di erosione controllano l'evoluzione morfologica dei versanti. Tali fenomeni innescati in genere da forzanti meteorologiche o sismiche, sono dipendenti da tutti gli elementi che coesistono nel versante.
Particolarmente significativo è il ruolo svolto dalla vegetazione che controlla direttamente e indirettamente i processi di formazione del suolo e le sue caratteristiche fisico chimiche. Ad esempio la resistenza al taglio, la porosità, o la permeabilità di un suolo possono essere fortemente modificate dalla vegetazione. Le diverse specie vegetazionali, ma anche la loro frequenza e distribuzione spaziale possono far variare localmente le caratteristiche del suolo e modificare i processi di infiltrazione del versante influenzando direttamente i processi di frana e di erosione superficiale. Nel caso di frane di crollo la vegetazione costituisce un ostacolo naturale al movimento dei massi sulla superficie agendo come un'opera di protezione naturale.
Gli eventi naturali che modificano la distribuzione e le comunità vegetali di un versante possono quindi avere un'influenza diretta sui processi di frana ed erosione superficiale. Tra questi gli incendi possono modificare fortemente nel versante sia la vegetazione che la parte di suolo più superficiale con conseguente variazione delle condizioni locali di innesco di frana e processi erosivi canalizzati. Di fatto determinare le mutue relazioni dei vari elementi che costituiscono un versante e ricostruire come esse interagiscono anche sotto la forzante di eventi naturali esterni è complesso. Tale complessità si riflette nella determinazione degli effetti a loro volta indotti sulle dinamiche del versante, anche per le diverse interazioni da analizzare considerando diverse tipologie di fenomeni di instabilità.
Per tali motivi la valutazione della risposta del versante in termini di aumento della suscettibilità idrogeologica indotta dagli incendi boschivi è stata affrontata analizzando specifici tipi di modellazione per i diversi fenomeni di instabilità quali_
oFrane superficiali;
oProcessi di erosione canalizzati;
oCadute massi.
Tale suddivisione è stata dettata sia dalla diversità dei fenomeni individuati, ma anche in considerazione dei diversi inneschi che causano preferenzialmente tali fenomeni. Infatti le frane superficiali e i processi erosivi canalizzati sono preferenzialmente innescati da piogge intense e/o prolungate, mentre le cadute massi occorrono con maggior frequenza durante gli eventi sismici.
I modelli individuati per le varie tipologie di fenomeno sono differenti e contemplano diverse strategie di inclusione degli effetti indotti dagli incendi.
Per le frane superficiali saranno utilizzate le soglie pluviometriche di innesco di frana che sono modelli empirici basati sulla ricostruzione delle relazioni esistenti tra la pioggia e il tempo di innesco delle frane. Tali soglie sono definite come minime condizioni pluviometriche di innesco, caratterizzate dalla cumulata (o dall'intensità media) e dalla durata di pioggia, oltre le quali le frane possono occorrere. La determinazione della variazione di tali soglie a seguito di incendi è possibile solo dove si hanno informazioni sui tempi di innesco di frane per aree incendiate. Essendo modelli di tipo empirico, l'incertezza legata a tale determinazione è funzione della numerosità/qualità delle informazioni disponibili. Un'analisi più completa in materia di soglie empiriche di pioggia è riportata nel Capitolo 4.
Per i processi di erosione canalizzati sono invece utilizzati modelli basati su soglie morfometriche, che determinano i valori minimi di area contribuente e pendenza oltre le quali è possibile l'innesco di tali fenomeni erosivi. Tali modelli possono integrare il ruolo svolto da dai diversi tipi di suolo e delle relative condizioni idrologiche. La determinazione della variazione delle condizioni di innesco di tali fenomeni a seguito di incendi è possibile quindi introducendo le modifiche di uso del suolo e delle relative caratteristiche osservate nelle aree incendiate.
Per le cadute massi saranno utilizzati modelli fisicamente basati che descrivono i movimenti di massi lungo un versante includendo direttamente o indirettamente la vegetazione. La determinazione della variazione delle condizioni di innesco di tali fenomeni a seguito di incendi è possibile quindi modificando i parametri di input dei modelli relativi alla vegetazione così some osservati nelle aree incendiate.
Nel presente documento sono descritti in particolare_
ogli effetti del fuoco sugli elementi che coesistono nel versante (Capitolo 2);
ogli effetti del fuoco sulle dinamiche di versante, considerando in particolare frane di tipo superficiale e processi di erosione (Capitolo 3);
ole soglie di pioggia per il possibile innesco di frane nelle aree in esame (Capitolo 4);
oi risultati dell'analisi preliminare della variazione delle condizioni di innesco di frane superficiali e delle relative soglie (Capitolo 5).
Infine nel Capitolo 6 sono riportate alcune considerazioni su quanto precedentemente descritto.

Early warning systems can predict rainfall-induced landslides by comparing rainfall data with landslide rainfall thresholds. These systems are based on empirical rainfall thresholds defined using rain gauges data. Despite quantitative satellite rainfall estimates are currently available, limited research has compared satellite estimates and rain gauge measurements for the forecasting of possible landslide occurrence. In this work, we validate satellite estimates obtained for Italy by the NASA Tropical Rainfall Measuring Mission (TRMM) against rainfall measurements from the Italian rain gauge network (< 1950 rain gauges), in the period from 1 September 2009 to 31 August 2010. Using cumulative rainfall measurements/estimates, we_ (i) evaluate the correlation between the rain gauge measurements and the satellite estimates in different morpho-climatological domains, (ii) analyse the distributions of the ground-based measurements and the satellite estimates using different statistical approaches, and (iii) compare rainfall events derived automatically from satellite and rain gauge rainfall series. We observe differences between satellite estimates and rain gauge measurements in different morpho-climatological domains. The differences are larger in mountain areas, and collectively reveal a complex relationship between the ground-based measurements and the satellite estimates. We find that a power law correlation model is appropriate to describe the relation between the two rainfall data series. We conclude that specific rainfall thresholds must be defined to exploit satellite rainfall estimates in existing landslide early warning systems.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

In the framework of the European Soil Thematic Strategy and the associated proposal of a Framework Directive on the protection and sustainable use of soil, landslides were recognised as a soil threat requiring specific strategies for priority area identification, spatial hazard assessment and management. This contribution
outlines the general specifications for nested, Tier-based geographical landslide zonings at small spatial scales to identify priority areas susceptible to landslides (Tier 1) and to perform quantitative susceptibility evaluations within these (Tier 2). A heuristic, synoptic-scale Tier 1 assessment exploiting a reduced set of geoenvironmental factors derived from common pan-European data sources is proposed for the European Union and adjacent countries. Evaluation of the susceptibility estimate with national-level landslide inventory data suggests that a zonation of Europe according to, e.g. morphology and climate, and
performing separate susceptibility assessments per zone could give more reliable results. To improve the Tier 1 assessment, a geomorphological
terrain zoning and landslide typology differentiation are then applied for France. A multivariate landslide susceptibility
assessment using additional information on landslide conditioning and triggering factors, together with a historical catalogue of
landslides, is proposed for Tier 2 analysis. An approach is tested for priority areas in Italy using small administrative mapping
units, allowing for relating socioeconomic census data with landslide susceptibility, which is mandatory for decision making regarding
the adoption of landslide prevention and mitigation measures. The paper concludes with recommendations on further
work to harmonise European landslide susceptibility assessments in the context of the European Soil Thematic Strategy.

Contractional architecture within the compressive edges of mountain
belts is dominated by thrust faulting. Thrust faults of regional extent
produce the emplacement of thrust nappes along low angle faults spanning
for of kilometres. The erosion, and related removal, of connecting
portions of a nappe may isolate remnant portions of the nappe, or
klippen. The process results in exotic rock blocks of different sizes
resting on the hanging wall of low angle faults. This simple structural
architecture may be misinterpreted because as the result of a more
complex deformation history. Studying the meaning of exotic rock blocks
along a thrust fault of regional extent in the Southern Apennines,
Italy, we show that previously interpreted thrust-related klippe are the
products of a subsequent deformation stage overprinting the thrust
features. A suite of low angle, foreland direct, brittle faults
developed during the younger deformation stage were recognised in the
studied exotic rock blocks. Low angle faults merge at the basal tectonic
contacts of the rock blocks, and truncate thrust-related structures in
the footwalls. The low angle faults cut down-section into the footwalls,
and appear extensional. The meaning of the low-angle extensional faults
is discussed in the framework of the transition tectonics from
syn-orogenic contraction to late/post orogenic extension, accompanied in
the Southern Apennines by intense uplift. We interpret the extensional
tectonic fabrics as the products of a heterogeneous deformation
resulting in progressive tilting of weak interfaces. In the structures,
gravity sliding processes can induce normal faulting compatible with a
thrust regime. The findings has implications for the reconstruction of
the history of deformation of a large sector of the Southern Apennines,
Italy.

Landslides are present in all continents, and play an important role in the evolution of landscapes. They also
represent a serious hazard in many areas of the world. Despite their importance, we estimate that landslide
maps cover less than 1% of the slopes in the landmasses, and systematic information on the type, abundance,
and distribution of landslides is lacking. Preparing landslide maps is important to document the extent of
landslide phenomena in a region, to investigate the distribution, types, pattern, recurrence and statistics of
slope failures, to determine landslide susceptibility, hazard, vulnerability and risk, and to study the evolution
of landscapes dominated by mass-wasting processes. Conventional methods for the production of landslide
maps rely chiefly on the visual interpretation of stereoscopic aerial photography, aided by field surveys.
These methods are time consuming and resource intensive. New and emerging techniques based on satellite,
airborne, and terrestrial remote sensing technologies, promise to facilitate the production of landslide maps,
reducing the time and resources required for their compilation and systematic update. In this work, we first
outline the principles for landslide mapping, and we review the conventional methods for the preparation of
landslide maps, including geomorphological, event, seasonal, and multi-temporal inventories. Next, we
examine recent and new technologies for landslide mapping, considering (i) the exploitation of very-high
resolution digital elevation models to analyze surface morphology, (ii) the visual interpretation and semi-
automatic analysis of different types of satellite images, including panchromatic, multispectral, and synthetic
aperture radar images, and (iii) tools that facilitate landslide field mapping. Next, we discuss the advantages
and the limitations of the new remote sensing data and technology for the production of geomorphological,
event, seasonal, and multi-temporal inventory maps. We conclude by arguing that the new tools will help to
improve the quality of landslide maps, with positive effects on all derivative products and analyses, including
erosion studies and landscape modeling, susceptibility and hazard assessments, and risk evaluations.

During the 20th century, floods in Italy have killed or injured more than 4750 people in
at least 916 fatal flood events, at 739 different sites (Salvati et al., 2010). In the same
period, the number of homeless and evacuees caused by inundations exceeded 530 000.
These figures indicate that flood risk to the population is severe and widespread in
Italy. Consequently, establishing flood risk levels is a problem of both scientific and
societal interest.
Estimates of individual and collective risk levels in Italy were first determined by
Salvati et al. (2003), and were revised by Guzzetti et al. (2005a,b) and by Salvati et al.
(2010). In this Chapter, we use an improved version of the catalogue of flood events
with human consequences in Italy (Salvati et al., 2003, 2010; Guzzetti et al., 2005b) to
update the existing estimates of individual and societal flood risk in Italy and in the 20
Italian regions. Next, we investigate the temporal and the geographical variations of
flood risk in Italy, and we compare the national flood risk levels to the levels of risk
posed by other natural hazards, including landslides, earthquakes and volcanic activity.
Here, we use the term fatalities to indicate the sum of the deaths and the missing
persons caused by a harmful flood event. Casualties indicate the sum of fatalities and
injured people. Evacuees are people forced to abandon their homes temporarily, while
the homeless are people that lost their homes. Human consequences encompass
casualties, homeless people and the evacuees. A fatal event is an event that resulted in
fatalities. Individual risk is the risk imposed by a hazard to any unidentified individual.
Societal (or collective) risk is the risk imposed by a hazard on society as a whole.
