The study of ancient major rock slope instabilities may help in the detection of the conditions leading to their development, so
that consequences and possible prevention and mitigation actions can be envisaged.
In this paper, numerical studies have been carried out to recognize the behavior of a rock slope and the kinematics of a rock
slide/avalanche in the north-eastern Italian Alps. The "La Marogna" rock avalanche, in the Vicenza Province (Venetian Pre-Alps,
North-Eastern Italy), with a volume of about 17*106 m3 still partially dams the narrow valley of the Astico River. Geomorphological
investigations highlight that the whole rock avalanche mass is formed by two distinct overlapping bodies and that apparent poor
stability conditions characterize the slope above the present main scarp.
In order to get indications about triggering factors and present stability conditions, a representative engineering geological
model has been built and analyses of the triggering conditions have been performed using the bi-dimensional continuum (FLAC) and
discontinuum (UDEC) codes UDEC on the re-constructed original slope profile. Different situations have been simulated for gaining
a better understanding of the effect of static and dynamic loads on the modeled rock slope.
The numerical results indicate that the effect of a contemporary dynamic loading and joint friction decrease results in the
instability of a rock mass limited at its bottom by both bedding and a pre-existing discontinuity.

The stochastic models, developed to simulate long-term hydrological data, can be subdivided in "driven data" models, which reproduce the principal characteristics of the available data series, and "physically
based" models, which schematize the generating mechanism of atmospheric precipitation. The initial step of a "driven data" stochastic model, able to adequately simulate the sequences of wet and dry days,
is the definition of the statistics of the model. In this paper, various statistical models for sequences of no-rain days are firstly presented_ the models are based on an approach which considers the arrival of
rainfall events as a Poisson process, homogenous or not. Moreover, the first results of an application of one of these models to the daily rainfall series registered at the Cosenza rain gauge (Calabria, Southern
Italy) are also shown. In particular, the model applied is a non-homogeneous Poisson model which considers the rainfall as a pulse of random duration.

Complex and rugged topography induces large variations in erosion and sediment delivery in the headwaters of alpine catchments. An effective connection of hillslopes with the channel network results in highly efficient sediment transfer processes, such as debris flows. In contrast, morphological conditions producing decoupling of hillslopes from channels (e.g. glacial cirques) may exclude large areas of the catchment from sediment delivery to its lower parts. Moreover, an efficient connection between hillslopes and channel network does not always ensure an effective downstream transfer of sediment. Low-slope channel reaches (e.g. in hanging valleys) cause sediment deposition, which often results in changes of the sediment transport processes, typically from debris flow to streamflow with low bedload and suspended load rates. The availability of high-resolution digital terrain models, such as those derived from aerial LiDAR, improves our capability to quantify the topographic controls on sediment connectivity. A geomorphometric index, based on the approach by Borselli et al. (2008), was developed and applied to assess spatial sediment connectivity in two small catchments of the Italian Alps featuring contrasting morphological characteristics. The results of the geomorphometric analysis were checked against field evidences, showing good performance and thus potential usefulness of the index.

L'utilizzo delle risorse idriche sotterranee è iniziato in Calabria con la progressiva captazione delle numerose sorgenti ed è via via aumentato, a partire dai primi decenni del secolo scorso, mediante la perforazione di numerosi pozzi, oramai diverse decine di migliaia. Oggi la quasi totalità delle acque potabili utilizzate in Calabria, più di quanto accade nel resto della nazione, proviene dalle acque sotterranee.
La Calabria è una regione le cui peculiarità geologiche, idrogeologiche e climatiche la hanno resa ricca di risorse idriche. Tali caratteristiche naturali non sono state però sufficienti a impedire ricorrenti eventi siccitosi, anche nei più recenti decenni. Tali risorse, evidentemente di interesse strategico per la regione, sono soggette a prelievi crescenti, per effetto di una domanda in costante aumento, e a uno stressante e tendenziale calo della ricarica, dovuto alle variazioni climatiche. L'effetto complessivo è che i principali acquiferi risultano, con delle differenze di caso in caso, soggetti agli effetti preoccupanti dell'inquinamento e del sovrasfruttamento.
Ciò premesso, il contributo si pone l'obiettivo, a partire dalla disamina delle condizioni naturali, con particolare riferimento agli aspetti idrogeologici, di descrivere la rilevanza delle risorse idriche sotterranee regionali, di individuare i punti di forza del loro utilizzo e, allo stesso tempo, di focalizzare su i rischi di degrado qualitativo e quantitativo delle risorse stesse.
Descritti i caratteri idrogeologici dei principali complessi idrogeologici e dei principali acquiferi presenti nella regione, si individuano i principali fattori del rischio di degrado delle risorse idriche sotterranee. Gli acquiferi presenti in Calabria sono soggetti a rischi di degrado qualitativo, per l'intrinseca vulnerabilità degli acquiferi e per la rilevanza del carico inquinante antropico, potenzialmente fonte di pericolo, e a rischi di degrado quantitativo, in relazione alla crescente e spesso insoddisfatta domanda idrica, che determina condizioni di sovrasfruttamento delle risorse idriche sotterranee. Nel caso della Calabria, visto che la gran parte degli acquiferi principali sono costieri, il rischio derivante dagli effetti dell'intrusione marina lega in modo duale i rischi di degrado quantitativo a quelli di natura quantitativa. Lo studio delle acque sotterranee della Calabria deve quindi essere contestualizzato in quello più ampio, a scala globale, che affronta la gestione degli acquiferi costieri, il caso più complesso di gestione di risorse idriche sotterranee.

Sediment transport rate in mountainousstreams is strongly controlled by sediment yield due to erosion and
landslides, therefore giving a valuable contribution in the definition of the state of activity and potential impact of
active landslides. However, a comprehensive monitoring system of sediment dynamics is usually very expensive,
time consuming and above all technologically complicated. In this paper we compare two different approaches
used in two test sites in Japan and Italy.
The difficulties in directly monitoring of traction processes have been widely recognized and prompted research
towards indirect monitoring techniques, including acoustic and seismic methods.Recently, a new method to
indirectly measure the volume of bedload transport from sound pressure data, provided by hydrophones, was
proposed. The preliminary results of the measurement campaigns in the Japanese test site will be here
presented showing that the bedload transport rate evaluated by hydrophone fit very well with the data gathered
by direct sampling for both long- and short-term time spans.
Inthe Italian test site, a geomorphometric approach, consisting in computing the difference of DTMs derived from
LiDAR data acquired at different times, has been carried out at catchment scale helping assessing the loss of soil
caused by erosion processes and in the identification of areas of sediment deposition during a specified time
span.This approach is suitable for the study of processes with higher magnitude than sediment transport causing
morphological variations higher than the propagated DTMs errors (i.e. debris flow).
The possible integration of these approaches can cover a wide range of sediment transport processes (from
suspended sediment to debris flow) that affect mountain basins. Therefore, the resultsso far obtained clearly
show that these analyses can be functional in establishing a comprehensive management plan for a sustainable
land use, and in designing of mitigation works.

A very detailed geodatabase of floods, landslides and debris flows is available and kept up to date for the
territory of the Autonomous Province of Bolzano, in northeastern Italy (7400 km2). The database is fed by field
surveys carried out after the occurrence of instability phenomena and reports locations and attributes of the
events for the last 15 years. The on-site analysis grants the gathering of important information and
documentation resulting from field measurements and interviews to witnesses of the events. Particular attention
is paid to the recognition of location, magnitude and path of landslides and debris flows.
Data on shallow landslide locations and debris-flow initiation sites have provided the input to a regional-scale
debris flow model aimed at the assessment of debris flow paths and inundation areas. A simple mass
propagation model based on topographic attributes (Huggel et al., 2003) has been applied to simulate mass
movement phenomena for selected basins using initiation sites listed in the regional database. In the model,
debris-flow propagation is given in probability-related values representing the hazard potential for the selected
locations. All the simulations have been carried out using a high-resolution (2.5m) LiDAR-derived Digital Terrain
Model (DTM).
The combination of a georeferenced database of landslides and debris flows and a simple topography-based
model constitutes therefore a reliable tool for a fast and preliminary debris-flow hazard estimate, assessment and
mapping.

The geomorphological change detection through the comparison of repeated topographic surveys is a recent
approach that greatly benefits from the latest developments in topographical data acquisition techniques. Among
them, airborne LiDAR makes the monitoring of geomorphological changes a more reliable and accurate
approach for natural hazard and risk management. In this study, the analysis of multi temporal LiDAR-DTMs
acquired just before and after a complex landslide event (4th November 2010) in the Rotolon catchment (Small
Dolomites, Italy), was used to set up the initial condition for the application of a dynamic model.
The 2010 event detached a mass of 320.000 m3 from the south slope of Mt. Rotolon partially evolving in a debris
flow that stretched for 4.5 km threatening some villages. Pre- and post-event DTMs derived from LiDAR with 2 m
resolution were available. The comparison between the DTMs was carried out considering the error propagation.
The resulting differential DTM was analyzed in order to identify erosion and depositional areas related to the
event and to quantify them in terms of volume.
The knowledge of the dynamics of the phenomenon allowed to back-analyze the event with a dynamic numerical
3D model. DAN3D code was selected because it allows to modify the rheology and the parameters of the moving
mass during the run-out. This behaviour was observed along the path of the debris-flow where the mobilized
mass encountered rheological modifications due to the hydric contribution of tributary streams and the
entrainment of eroded material. Considering these aspects a sound simulation of the 2010 event was computed.
Nowadays some portions of Mt. Rotolon flank are still moving and showing precursor signs of detachment. The
same soil parameters used in the back-analysis model were used to simulate the run-out for three possible
landslides flows allowing to generate reliable risk scenarios that could be used for creating civil defense
emergency plans.

spatial and ...
The description and quantification of landscape changes as modulated by geomorphic processes, at different
spatial and temporal scales, constitute the core of modern geomorphic research. The high resolution and
accuracy of currently available airborne digital terrain models (DTMs) allow the development of new methods for
the quantitative monitoring of geomorphic changes. In this context, DTM of difference (DoD), which can be
created by subtracting one elevation model from another, represents a convenient way to estimate volumetric
changes across landscape components between successive topographic surveys.
In this contribution we quantify the topographic variations associated with the activity of rapid geomorphic
processes (e.g., debris slides and debris flows) in Gadria and Strimm catchments, two adjacent basins, covering
a total area of 14.7 km2, in the Eastern Italian Alps. To this purpose we perform DoD on two LiDAR-derived
DTMs (2 m resolution), acquired respectively in the summer of 2006 and 2011, applying a fuzzy logic-based
method (Wheaton et al., 2010) which considers the uncertainty in the surface representation of the topographic
data.
Results indicate that shallow rapid failures and channelized processes such as debris flows and debris floods
have been by far the dominant processes in both basins over the study period. In particular, we are able to track
the effects of a debris-flow event (July 12th 2010) originating on the western slopes of Strimm basin and that has
been estimated to transport 15,000 m3 of sediment down to the confluence with Gadria Creek. Not surprisingly,
upland terrain characterized by subdued topography and dominated by slow periglacial processes does not
exhibit any appreciable change.

Braided rivers are dynamic and complex environments shaped by the balance of the flow and sediment regimes and by the influence of the riparian vegetation and disturbances such as floods. In particular, the balance between sediment supply and transport capacity can determine the morphological evolution of a river. For instance, aggrading and widening trends are distinctive of reaches where sediment supply is higher than transport capacity. In contrast, incising and narrowing tendencies are dominant. The aim of the present study is to analyze the short-term morphological dynamics and the processes of erosion and sediment deposition along a small reach of a relatively unimpacted gravel-bed braided river (Tagliamento River, northeast Italy) using a terrestrial laser scanner (TLS). The study area is around 23. ha and has been surveyed before after two periods with relevant flood events, two of which were higher than the bankfull level and occurred between September 2010 and September 2011. The very high point clouds density allowed us to derive three high resolution digital elevation models (DEMs) with 0.125. ×. 0.125. m pixel size. Scan data cloud merging was achieved with an overall high degree of accuracy and resolution (subcentimeter). Topographic data were more accurate for exposed surfaces than those collected in wet areas. A detailed net of dGPS control points allowed us to verify the high quality of the DEMs derived from the surveys (RMSE of about 5. cm). Two DEMs of difference (DoD) were computed, revealing different and consistent episodes of erosion and deposition within the analyzed area, and changes in morphology of channel and bars could also be detected, such as bar edge accretion and bank erosion demonstrating a strong dynamicity of the Tagliamento River. Moreover, a very detailed estimation of the surface roughness in the study area has been carried out, permitting a large-scale analysis of the roughness values distribution. The results of the analysis on the TLS collected data show that along a river with a high natural character (i.e., Tagliamento River), the dynamic processes are also common during low magnitude events.

Genetic algorithms (GAs) are general-purpose search algorithms widely employed in different fields of science and engineering
as both optimization algorithms and scientific models of evolution. Theoretical foundations and the success in
first practical applications have stimulated the study on GAs and new classes of algorithms have been proposed in the
literature. In particular, multiobjective GAs are gaining the attention of the scientific community as powerful search
algorithms for complex problems. Applications of GAs in geomorphology are quite recent. The first applications can be
dated back to the late 1990s, whereas applications of multiobjective versions are still more recent. However, this specific
application field is growing and, even if today underutilized, we anticipate it will become significantly more widespread in
the next few years. This chapter provides an overview of GAs, both in their single- and multiobjective versions, and of their
applications through a few meaningful examples, with the aim of providing both a starting reference point and inspiring
new applications of GAs in geomorphology.

This contribution is based on the analysis of different types of data recorded to provide monthly time series related to climate (rainfall, wet days, rainfall intensity and temperature) from 1877 to 2008, in order to verify the relationship between climate changes and landslide occurrence in Apulia region. Despite the decreasing trend of rainfall and rainfall intensity and the increasing trend of temperatures and wet days, there is an increasing trend of landslide occurrence, highlighting the negative effect of anthropogenic activities in landslide-prone areas.

Mount Rotolon (Eastern Italian Alps) is affected by a complex landslide that, since 1985, is threatening the nearby village of Recoaro Terme. The first written proof of a landslide occurrence dated back to 1798. After the last re-activation on November 2010 (637 mm of intense rainfall recorded in the 12 days prior the event), a mass of approximately 320.000 m3 detached from the south flank of Mount Rotolon and evolved into a fast debris flow that ran for about 3 km along the stream bed. A real-time monitoring system was required to detect early indication of rapid movements, potentially saving lives and property. A web-based platform for automatic and continuous monitoring was designed as a first step in the implementation of an early-warning system. Measurements collected by the automated geotechnical and topographic instrumentation, deployed over the landslide body, are gathered in a central box station. After the calibration process, they are transmitted by web services on a local server, where graphs, maps, reports and alert announcement are automatically generated and updated. All the processed information are available by web browser with different access rights. The web environment provides the following advantages_ 1) data is collected from different data sources and matched on a single server-side frame 2) a remote user-interface allows regular technical maintenance and direct access to the instruments 3) data management system is synchronized and automatically tested 4) a graphical user interface on browser provides a user-friendly tool for decision-makers to interact with a system continuously updated. On this site two monitoring systems are actually on course_ 1) GB-InSAR radar interferometer (University of Florence - Department of Earth Science) and 2) Automated Total Station (ATS) combined with extensometers network in a Web-based solution (CNR-IRPI Padova). This work deals with details on methodology, services and techniques adopted for the second monitoring solution. The activity directly interfaces with local Civil Protection agency, Regional Geological Service and local authorities with integrated roles and aims.

The monitoring of the acoustic emissions (AEs) due to rock fracturing allows the detection of the rockfall precursor signals, leading to a strong improvement of the real time assessment of the induced risk. A network of piezoelectric sensors (PZTs) provides reliable AE data, as testified by a series of applications in non-destructive testing, but PZTs are strongly affected
by lightings and electromagnetic interference. In order to avoid such PZT drawbacks and limitations and therefore to allow the rock fracturing monitoring in unstable slopes, two FOS architectures (referred to as fibre coil sensor and ferrule top cantilever) have been recently proposed in previous works from the same authors. In this paper, the two sensors are tested in a more realistic
scenario, by monitoring AE in a rock block in which crack is induced by highly expansive mortar; complementary activities, mainly aimed at the recognition of the type of expected signals and optimisation of the sensor array in the framework of the monitoring system, are also described here.

This study investigates the capability of the Moderate resolution Imaging Spectroradiometer (MODIS) to estimate river discharge, even for ungauged sites. Because of its frequent revisits (as little as every 3. h) and adequate spatial resolution (250. m), MODIS bands 1 and 2 have significant potential for mapping the extent of flooded areas and estimating river discharge even for medium-sized basins. Specifically, the different behaviour of water and land in the Near Infrared (NIR) portion of the electromagnetic spectrum is exploited by computing the ratio (C/M) of the MODIS channel 2 reflectance values between two pixels located within (M) and outside (C), but close to, the river. The values of C/. M increase with the presence of water and, hence, with discharge. Moreover, in order to reduce the noise effects due to atmospheric contribution, an exponential smoothing filter is applied, thus obtaining C/M*.Time series of hourly mean flow velocity and discharge between 2005 and 2011 measured at four gauging stations located along the Po river (Northern Italy) are employed for testing the capability of C/M* to estimate discharge/flow velocity. Specifically, the meanders and urban areas are considered the best locations for the position of the pixels M and C, respectively. Considering the optimal pixels, the agreement between C/M* and discharge/flow velocity is fairly good with values in the range of 0.65-0.77. Additionally, the application to ungauged sites is tested by deriving a unique regional relationship between C/M* and flow velocity valid for the whole Po river and providing only a slight deterioration of the performance. Finally, the sensitivity of the results to the selection of the C and M pixels is investigated by randomly changing their location. Also in this case, the agreement with in situ observations of velocity is fairly satisfactory (r~. 0.6). The obtained results demonstrate the capability of MODIS to monitor discharge (and flow velocity). Therefore, its application for a larger number of sites worldwide will be the object of future studies.
