What’s underneath?
When soil behaviour is studied, whether landslide soils are concern, levee materials or foundations, the problem regarding how much and how reliable information about the soil properties we have available has to be addressed.
Understanding “what’s beneath” the visible surface is fundamental, yet complicated. Drillings are performed to analyse the stratigraphy of soils (the order and the thickness of the different soil levels) and ... Debris-flow monitoring in the Alps
Not all that flows in creeks is water. Debris flows i.e., surges in which solid particles move together with little water, may occur in steep mountain streams, mainly as a consequence of intense rainfall. Debris flows have a high kinetic energy, and may cause major damage if they encroach buildings, roads and bridges. They are also a primary cause of landslide casualties. The video below shows an example of debris flows.
The low ... Landslide susceptibility models and maps
Landslide susceptibility is the likelihood of a landslide occurring in an area, given the local terrain conditions. It is the degree to which an area can be affected by future landslides i.e., an estimate of “where” landslides are more likely to occur.
Landslide susceptibility does not consider the temporal occurrence or the magnitude of the expected landslides. In mathematical language, landslide susceptibility can be expressed as the ... Role of climate change in the morphogenesis of glacial-periglacial environments and analysis of associated risks
Climate change in the Greater Alpine Region is seriously affecting glacial and periglacial areas, especially for the presence of snow, glaciers and permafrost (cryosphere), with relevant consequences on slope stability. Cryosphere degradation, changes of the precipitation and temperature patterns and of the hydrological regimes, are some of the main terrestrial indicators of climatic change. Moreover, the increasing number of tourists and human ... Geological investigations in the catchment of the Rio Kortol
Past debris flows in the Rio Kortol catchment arise concerns for the safety of the village of Sauris di Sotto, and urge new studies for the assessment of hazard and the choice of risk mitigation ... Rheology of geological processes
Critical and depositional friction angles are characteristic for the deposition of a granular mass; the wrong angle adoption determines the ineffectiveness of a containment basin. The term is used with different meanings and measured by various procedures. The numerical simulation is a useful tool for the hazard assessment, but the definition of friction needed parameters requires insights on their ... Landslides investigation and mitigation at Passo della Morte (UD)
L’area del "Passo della Morte" (UD) è interessata da una situazione di grave dissesto a causa della presenza di più movimenti franosi. Questi sono caratterizzati da elevata pericolosità in relazione alle caratteristiche intrinseche dei fenomeni (volumetrie e velocità di spostamento), alla morfologia del versante ed alla geologia dell'area. La loro presenza mette a rischio la rete stradale che collega la Carnia con il Cadore e l’asta ... Large landslides: Monitoring, Modelling and Mitigation
The study of the dynamics of large landslide is a heuristic process based on the integration of multiple investigation techniques: geological and geomorphological analysis, monitoring systems (traditional and innovative) and numerical models. Risk mitigation may require major interventions that call for detailed studies on the specific ... Geomorphometry and sediment dynamics in mountain catchments
The aim of the geomorphometric analysis is to derive indices capable of characterizing the spatial variability of specific hydro-geomorphological processes (e.g., sediment connectivity, erosion and deposit). The growing availability of high-resolution topographic data has increased the interest in geomorphometry and its applications. Debris-flow monitoring in instrumented areas and flash-flood documentation are invaluable ways to gather field ... Moscardo Torrent – rainfall data and debris flow hydrographs
This dataset consists of rainfall data and debris-flow hydrographs recorded in the Moscardo Torrent (Carnic Alps, northeastern Italy).
The Moscardo Torrent was instrumented for debris-flow monitoring by CNR IRPI (Torino office) in 1989; the research was then continued in collaboration with the Padova office. Since 2010 the monitoring activities are carried on in collaboration with the University of Udine (Dept. of Agricultural and ... Rischio frana due accordi per nuovi studi
Breve articolo dell'1 luglio 2015, scritto sul Messaggero Veneto, in cui si parla dell'IRPI CNR impegnato in due accordi per la prevenzione del rischio frana nella Valle del ... Data on maximum annual rainfall in north-eastern Italy
The database includes annual maximum rainfall corresponding to durations of 1, 3, 6, 12, 24 hours and 1, 2, 3, 4, 5 days for approximately 800 raingauges in north-eastern Italy (Trentino, Alto Adige, Veneto and Friuli Venezia Giulia). The database contains data until 1997 for the Autonomous Province of Bozen-Bolzano, 1990 for the Autonomous Province of Trento, and 1996 for Veneto and Friuli Venezia ... Aerofototeca
The CNR IRPI archive preserves 170.000 aerial photographs useful for stereoscopic applications. Most part of those photographs were taken during a number of surveys carried out between 1954 and 2005 in tha Padan Plain, Triveneto and Liguria (Northern Italy) but some examples date from the 1920s, 1930s and 1940s.
In this documentation the effects of many floods and landslides events can be observed. In particular, we would mention the aerial ... Real-time monitoring of the “San Lorenzo” tunnel, Passo della Morte
The entrance of the tunnel "San Lorenzo" in Forni di Sotto (UD) has built over a an active landslide body. The gravitational deformations of the slope are damaging the lining of the tunnel and creating a hazardous ... Changing Hydro-meteorological Risks as Analyzed by a New Generation of European Scientists
The European Commission has identified the need for adaptations in risk management as a consequence to climate and environmental changes in several documents. The implementation of risk management measures such as disaster preparedness programmes, land-use planning, regulatory zoning and early warning systems are considered essential. Further, multi-risk assessment approaches are not used in planning practice: risk indicators are hardly used ... Study of the riverbeds morphological evolution through the digital terrain models multi-temporal analysis
The study of the evolution of the watercourses is traditionally based on the use of historical maps and aerial photographs for the comprehension of the planimetric changes and on the use of topographical sections in order to have also the measure of the altimetric change occurred in the considered time interval.
Through this approach it is possible, for the Po basin, to have the first indications of the main watercourses evolution starting ...
