Direct measurements of the hydrological conditions for debris flow occurrence and of flow behaviour are of the outmost importance for developing effective flow prevention techniques. An automated and remotely controlled monitoring system was installed in Acquabona Creek in the Dolomites, Italian Eastern Alps, where debris flows occur every year. Its present configuration consists of three on-site stations, located in the debris-flow initiation area, in the lower channel and in the retention basin. The monitoring system is equipped with sensors for measuring rainfall, pore-waterwater pressure in the mobile channel bottom, ground vibrations, debris flow depth, total normal stress and fluid pore-pressure at the base of the flow. Three video cameras take motion picture of the events at the initiation zone, in the lower channel and in the deposition area. Data from the on-site stations are radio-transmitted to an off-site station and stored in a host PC, from where they are telemetrically downloaded and used by the Padova University for study of debris flows. The efficiency of the sensors and of the whole monitoring system has been tested by the analysis of data collected so far. Examples of these data are presented and briefly discussed. New applications of the used technology, derived by the development of this system, if implemented to the numerous debris flows existing in the Dolomitic Region, will provide civil defence and residents of warning of impending debris flows.

Project RUNOUT has investigated methods for reducing the risk from large-volume landslides in Europe, especially those involving rapid rates of emplacement. Using field data from five test sites (Bad Goisern and Köfels in Austria, Tessina and Vajont in Italy, and the Barranco de Tirajana in Gran Canaria, Spain), the studies have developed (1) techniques for applying geomorohological investigations and optical remote sensing to map landslides and their evolution, (2) analytical, numerical and cellular-automata models for the emplacement of sturzstroms and debris flows, (3) a brittle-failure model for forecasting catastrophic slope failure, (4) new strategies for integrating large-area GPS arrays with local geodetic monitoring networks, (5) methods for raising public awareness of landslide hazards, and (6) GIS-based databases for the test areas. The results highlight the importance of multidisciplinary studies of landslide hazards, combining subjects as diverse as geology and geomorphology, remote sensing, geodesy, fluid dynamics, social profiling. They have also identified key goals for improved understanding of the physical processes that govern landslide collapse and runout, as well as for designing strategies for raising public awareness of landslide hazards and for implementing appropriate land-management policies for reducing landslide risk.

Collecting information on landslide occurrence and activity over wide areas is a crucial task for landslide hazard assessment. Field techniques, despite being very precise, are usually not sufficient to achieve this goal, since they mostly provide point-based measurements. Mainly because of its synoptic view and its capability for repetitive observations, optical (visible-infrared) remotely sensed imagery acquired at different dates and at high spatial resolution can be considered as an effective complementary tool to field techniques to derive such an information.
An image processing method to map and monitor landslide activity using multitemporal optical imagery is proposed. The method entails automatic change detection of suitably pre-processed (geometrically registered and radiometrically normalised) sequential images, followed by thresholding into landslide-related change pixels. Subsequent filtering based on the degree of rectangularity of regions can also be considered to eliminate pixel clusters corresponding to man-made land use changes.
The application of this method is illustrated in the complex Tessina landslide, in the Eastern Italian Alps. It has focused on discriminating the effects of a major reactivation occurred in 1992, hence inferring the dynamics of the landslide at that time. Although the method has been devised for optical remote sensing imagery in general, in the absence of high-resolution satellite imagery covering that period, digital images from existing aerial photograph diapositives scanned at 1-m pixel size have been used. The method is able to classify image pixels according to landslide activity conditions.

An innovative technique, based on radar interferometry and implemented using ground-based instrumentation, has been applied for monitoring the Tessina landslide (Italy, Belluno). The technique has allowed us to derive multi-temporal surface deformation maps of the entire depletion zone of the landslide with a high resolution and accuracy. The portable device used in this application is known as LISA (Linear SAR) and it is able to provide measurements at 17 GHz with a synthetic aperture of up to 2.8 m. The results have been validated by comparing the recorded pixel displacements with independent measurements carried out by a motorized theodolite and EDM (Electronic Distance Meter) on two benchmarks.

The paper focuses on the channel network of alpine basins, attempting to interpret channel reaches in terms of response to erosion and deposition processes. Two basins in the Dolomites (north-eastern Italy) were considered_ the Rio Cordon (5 km^2) and the upper Boite River (163 km^2).The channel network was extracted from raster-type digital elevation models (DEM) using a slopearea threshold criterion. A contribution area index (CAI), which combines drainage area, A , and local slope, S (CAI=A^0.5*S), was used to identify channel heads. The channel network extracted from the DEM was then analysed to recognize cells showing a value of CAI lower than the threshold adopted for channel initiation. Contiguous cells with low values of CAI define channel reaches with low transport efficiency. Field surveys carried out for some selected cases showed a good agreement between prevailing sediment deposition predicted by the analysis of the channel network and observed channel morphological features. Sediment sources mapped in two study basins were also analysed in relation to the location of channels with high potential for sediment deposition_
this made it possible to classify the potential role of different types of sediment sources with regard to basin sediment yield. Topographic characteristics of the channel network, expressed by CAI, were compared with a classification of channel morphology in the Rio Cordon. It was found that cells with low values of CAI frequently occur in the rifflepool reaches, whereas the percentage significantly decreases in steppool and bedrock channels.

Sediment gravity flows are very common sedimentary processes in the Alpine region and are often characterized
by rapid deposition of large amounts of material. Hazard evaluation in such mountainous areas
depends on proper identification of the dominant sedimentary processes, interpreted both from modern and
ancient sedimentary facies and their distribution. Three main groups of alluvial fans, characterized by different
dominant sedimentary processes, have been distinguished on the basis of lithological characteristics of
the catchment area. The dominant catchment lithologies are_
1 massive and/or crudely stratified carbonate rocks (dolomite and massive limestones);
2 fine-grained sedimentary and metamorphic rocks (schists, calc-schists, mica schists, slate, phyllites and
quartzites);
3 massive crystalline rocks (granites, granodiorites).
Their main characteristics are illustrated by three case studies concerning large debris-flow events that
occurred in the recent past. The comparison of sediment texture and grain-size distribution indicates that
important differences in the sedimentological features of debris flows are generated by the three different
rock types in the catchments. Colluvium lithology strongly controls the grain-size distribution of the debris
available on the catchment that is mobilized, transported and accumulated on the fan during catastrophic
flood events. The proportion of fine-grained particles (clay and fine silt) within the colluvium plays a key role
in controlling the dominant primary sedimentary processes. The study of 23 flood events over the past 30 yr
indicates that the catchments of group 1 and 2 fans produce large amounts of clay and fine silt, which
typically can lead to the generation of cohesive sediment gravity flows. Group 3 fan catchments produce
colluvium free of clay and fine silt that can be mobilized and transported by water flow processes, and which
in extreme flood events usually are associated with non-cohesive sediment gravity flows.

Field data on debris flows are of utmost importance for improving knowledge
of these hazardous phenomena and for the development of attenuation
measures. In alpine basins, debris flows generally occur with a frequency
high enough to create serious risk to human settlements and transportation
routes, but too low to justify monitoring activity capable of providing
enough data in a sufficiently short time. The Moscardo Torrent, a small
stream in the Eastern Italian Alps, is an exception to this general
situation since it displays a high frequency of debris flows (commonly at
least one event per year). In 1989, this torrent was instrumented and the
results of the following 10 years (19891998) of debris-flow monitoring are
presented, with an analysis of collected data. The equipment installed
allowed measurement of rainfall, flow stage and ground vibrations caused by
debris flows. Other important debris-flow variables, that is, mean front
velocity, peak discharge and flowing volume were estimated from
instrumental records. Video pictures have proved to be useful for the
visual interpretation of debris-flow waves and have made it possible to
estimate the surface velocity of debris flows. Recorded data are compared
with other experimental data sets collected and documented worldwide.
Advantages and shortcomings of different types of sensors are discussed
with relevance both for research monitoring purposes and for possible use
in debris-flow warning systems.

A model for the simulation of shallow landsliding triggered by heavy
rainstorms is analysed and discussed. The model is applied in two
mountainous catchments in the Dolomites (Eastern Italian Alps): the Cordon
catchment (5 km^2) and the Vauz catchment (1.9 km^2), where field surveys
provided a description of hydraulic and geotechnical properties of soils
and an inventory of landslide scars is available. The stability mapping
procedure, which is similar to that proposed by Montgomery and Dietrich
(1994 Water Resources Research 30_ 1153), combines steady-state hydrologic
concepts with the infinite slope stability model. The model provides an
estimate of the spatial distribution of the critical rainfall, which is the
minimum steady-state rainfall predicted to cause instability. The
comparison of the landslides observed in the study basins with model
predictions shows that the distribution of critical rainfall obtained from
the model provides a surrogate for failure initiation probability as a
function of topographic location.

This work proposes the study of the sedimentary processes compared with the sedimentary record of the Moscardo Torrent alluvial fan, located in the Eastern Italian Alps. This comparison allows us to better analyze and understand the role that such debris flow events have in building up the fan and reshaping its surface. Given the high frequency of debris flow events (from one to four per year) the Moscardo fan is a very good place where to study fan processes. This basin has been monitored since 1989 yielding a long sequence of events stage data and related rainfall. Facies analysis and sedimentological investigation of the fan deposits have been carried out within
this work in order to determine sediment distribution and define the main sedimentary processes responsible for the sediment transport and deposition on the fan. Utilizing the long series of recorded stage data, different hydrographs features have also been analyzed and compared with related sedimentary processes.

L'article présente quelques aspects

dans différentes zones des Alpes françaises.
Les relations entre, d'une part, la superficie et
la pente des cônes de déjection et d'autre part,
les caractéristiques morphométriques des bassins
versants (superficie et dénivelée spécifique)
ou la typologie des processus torrentiels
(transport solide par charriage, laves torrentielles)
ont été analysées. La superficie des
cônes de déjection est très peu reliée à celle du
bassin versant, alors qu'elle dépend fortement
de la largeur disponible dans le fond de la vallée
principale. La relation entre la dénivelée
spécifique du bassin versant et la pente du
cône de déjection est mieux définie. Les investigations
effectuées permettent, en outre, de
distinguer les cônes de déjection à forte pente,
présents à l'exutoire de bassins versants petits
et à forte dénivelée, où la forme de transport
solide prévalante est représentée par les laves
torrentielles, des cônes à faible pente,
construits par les torrents à charriage, dont les
bassins versants ont des superficies assez étendues
et une dénivelée spécifique relativement
faible. Ces résultats, qui confirment ceux obtenus
dans d'autres régions géographiques,
permettent de classifier les processus torrentiels
sur les cônes de déjection à partir de
simples paramètres morphométriques des bassins
versants et des cônes de déjection.

The Moscardo Torrent is a small mountain stream in the Italian Alps and presents a high frequency of debris flows. The basin has been monitored since 1989 and both rainfall data and debris flow occurrence have been recorded, these latter through ultrasonic gauges. This paper aims at giving a new contribution on the long debated question of the cause-effect link between rainstorms and debris flow triggering. A sample of 73 rainstorms 15 of which caused debris flows is considered in this study. The main characteristics of rainstorms (total rainfall amount, duration, average and 60 minutes maximum intensity) and antecedent precipitation are analysed. In the Moscardo basin comparatively low-intensity storms are sufficient to trigger debris flows. The results are compared with those of some well-known works on this topic and lead to conclude that, even in a single small basin, rainstorm characteristics play an important role but are not exhaustive in defining debris flow initiation conditions.
