Moscardo Torrent – rainfall data

prodotti-dati-archivio-Torrente_Moscardo_pluviometro-evidenza This dataset consists of rainfall data 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 Environmental ...

ALMOND-F, an ALarm and MONitoring system for Debris-Flows

The ALMOND-F equipment installed on the left bank of the Gadria torrent. The structure also includes a raingauge, a solar panel and the box containing the data logger ALMOND-F is an innovative unit for the microseismic detection of debris flows using a network of geophones.The microseismic detection of debris flows is more complex than other types of monitoring. Use of the geophones requires: (1) the selection of the level of amplification of the signal, which depends on the distance from the stream; (2) the selection of the sampling frequency of the seismic signal, which must be sufficiently high; (3) ...

Rheology of geological processes

evidenza-roger 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 ...

Cooperative Internet-of-Data Rural/Alpine Community Environment

evidenza-CIRCE-trattointermedio- Environmental sensor monitoring is continuously developing, both in terms of quantity (i.e. measurement sites), and quality (i.e. technological innovation). Environmental monitoring is carried out by either public or private entities for their own specific purposes, such as scientific research, civil protection, support to industrial and agricultural activities, services for citizens, security, education and information. The left Cenischia ...

Kinematic of debris flows using Large Scale Particle Image Velocimetry (LSPIV)

evidenza-KINOFLOW-reprojected Usually the video cameras installed within a debris-flow monitoring site have the role of recording videos to better understand the behavior of the event for an improved interpretation of its dynamic. The use of such cameras for Image Velocimetry purpose is still nowadays a ...

Geomorphometry and sediment dynamics in mountain catchments

evidenza-geomorfometria-dinamica-sedimento 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 ...

Sino-Italian Joint Laboratory on Geological and Hydrological Hazards

evidenza-sino-italian-joint-laboratory Both China and Italy are characterized by large mountainous areas, where natural hazards (e.g., geological and hydrological hazards such as debris flows, landsides, flash floods) are widespread and seriously threatening local society. It is noted that, almost 67% and 76% of the territories are covered by mountains in China and Italy, respectively and the youngest chains in the Eurasia, namely the Alps and the Tibetan Plateau, are characterized ...

Active alluvial fans in Calabria, Southern Italy

Conoide attiva presente allo sbocco del torrente Inerà sul fondovalle della Fiumara di Melito (Calabria ionica meridionale). Ortofoto, maggio 2013. Alluvial fans are known to be areas of high geomorphic activity, where debris flows and flash floods caused by intense and prolonged rainfall are a major hazard. In Calabria, southern Italy, alluvial fans are numerous. The exact age of the alluvial fans is seldom known, but most of the fans in Calabria are considered recent in age (Holocene).Due to the significant increase in urbanization in the last two centuries, many alluvial fans are ...

Debris-flow monitoring in the Alps

monitoraggio_debris_flow-evidenza 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 ...
