Vacations on the snow, comfort and relax in the heart of the Dolomites in Val of Fassa, Trentino. The debris flow of August started, in fact, on the opposite side because of the presence of very large debris deposits at the base of northeastern cliffs of Mount Antelao after a rock collapse occurred on November This topic has fike archived, and won’t accept reply postings. Therefore, as only a part of the surface of the Vallon d’Antrimoia changed after the event due to the erosion, with no significative influence on the hydrological simulation, we used the LiDAR Section 2 describes the materials and methods, divided in four sub-sections concerning: In this section, the models used for modeling rainfall-runoff and debris flow routing are presented.

The Arpav forecast is OK.

The storm event of the 4 August hit all the areas contributing to Ru Secco Creek. Both the historical basins where debris flows formed until ’50s and the new one of Arpv Salvela are debris flow dominated according to the geomorphic indexes: The Crux Expedition Award is an annual grant to encourage young climbers to try for adventurous objectives. GPS points corresponding to the check dams are also used for the pre-event DEM because they remained substantially unchanged. In cross-section F the behavior is analogous but for the absence of the initial moderate peak of solid discharge, reasonably due to an dolomti deposition.

The model computes the excess rainfall for each cell of the basin and routes it through the steepest path to the channel network. The photogrammetric restitution through the photos relative to the Ru Salvela Creek after the rock fall of November and before the debris flow event one is that shown in Figure 3awas carried out by using the software 3DF Zephyr Lo Brutto and Meli, About the characteristics of sediments forming the debris deposits that were eroded by runoff and debris flows, we can refer to the grain size analysis carried out through the frequency-by-weight method, folomiti five samples taken on the channelized initiation area of Chiapuzza debris flow about 1 km north located on the scree of Cadino dei Ross formed by the rocks collapsed from the overhanging rocky walls of Punta Ross Top.

The abundant runoff, caused by the high intensity rainfall on 4 Augustentrained about 52, m 3 of the debris material laying on the Vallon d’Antrimoia forming a debris flow surge that hit and eroded the debris deposit covering the downstream Ru Salvela Creek, increasing its volume, aboutm 3 of mobilized sediments.

If the valley is approaching 25 degrees by 10am you can almost guarantee that it will rain and storm in the afternoon for maybe hours.

Ru Secco Creek was not routed by debris flows since late 50s after works for transforming its right side generally affected by debris flows, into a ski resort area. This section concerns the reproduction of the entire phenomenon by models.

Mark Bull – on 23 Jun An explicit scheme is used to solve numerically the model equations with the time step computed according to the Courant-Friedrichs-Lewy stability condition. Kean – on 25 Jun Simulated hydrographs of solid-liquid a and solid discharge bQ and Q S respectively, corresponding to the the traces of the six sections of Figure 9.

This means an increase of the conductance coefficient and a decrease of the limit values of angle and velocity both for deposition and entrainment because the transported solid concentration decreases Armanini, In the reach from a location about m upstream the culvert to the inhabitated of San Vito di Cadore, the bed of the Ru Secco creek is protected by a series of check dams. This area, located in the Venetian Dolomites, is dominated by carbonatic Platform formations.

This debris flow routed downstream the confluence, flooding the parking of a resort area where three people died, and reached the village downstream damaging some buildings. Their difference 51, m 3 is the sediment volume that runoff entrained on the Vallon d’Antrimoia sloping plateau, upstream the Ru Salvela head. In the following 20 min the deposition and erosion on parking become consistent with the excavation of the channel just over the culvert Figures 12d—f that is responsible of the second solid discharge peak in cross—section E Figure 11b.

Consequently, the debris flow flooded from it causing three deaths in the parking of a resort area and partially damaging some buildings of the village of San Vito di Cadore downstream. The rainfall-runoff modeling for the five basins depicted in Figure 1 was carried out by the model of Gregoretti et al.

It initially flows between two rocky walls and after a drop, it runs on the bottom of the valley between the northern rocky slopes of Mount Antelao, where Ru Salvela Creek origins Figure 1and the slopes starting at the feet of the rocky massif between Bel Pra and Scotter tops along Northwest-Southeast direction.

In the same Figure S2the exit of the culvert just after the event appears mainly free. About m downstream the base of the overhanging rocky cliffs, the slope was reshaped, and, where needed, some protection works walls and pottings were built.

The values of these parameters are shown in Table 1 with those of CN and f C for rocky soil updated by Bernard A triggering model provided the debris flow hydrographs in the initiation areas, after using the simulated runoff.

Dolomites From the site of the Regional agency of Prevention and Protection of the environment of Dolomiri. In Figures 3a4 the debris thick layer covering the Ru Salvela and Ru Secco Creeks aboutm 3 according to the computations of section 3. This one for Dolomites http: Consequently, we zrpav the use of a methodology for simulating the cascade of the physical processes that origin a debris flow phenomenon by models.

This updated version, proposed by Gregoretti et al. The second method explores the behavior of the drainage area vs.

For these reasons, the properties and the characteristics of the debris material are assumed to be quite the same. Direct field surveys and the analysis of pre and post-event topography allowed the recognition of liquid and solid-liquid contributions to the occurred phenomenon and its main features, as well as the map of deposition and erosion depths.

Runoff of small rocky headwater catchments: Post edited at The discharges are expressed by the following relationships:. According to Mattea et al. The in general satisfactory reproduction of the phenomenon by models proved the reliability of both the used methodology and single models. The original law of Egashira and Ashida was adapted after eliminating the reasons for the equilibrium angle because it can lead to uncorrect results.

Park national Dolomites Bellunesi Nasce born to protect a territory of extraordinary landscape and naturalistic value between the Peaks of Feltre and the Mountain Serves. The flow pattern, for a better comparison between simulation and estimate of the deposited and eroded sediments volume, has been divided in five reaches: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

This field survey gave the general view of all the single phenomena that contributed to the formation and routing of the solid-liquid surge along the Ru Secco Creek. Experimental evidences and numerical modelling of debris flow initiated by channel runoff. Outdoor Research is combining its decades of experience building highly dexterous, durable gloves with an innovative new material The upper image a is the general view of the areas routed by debris flows and subjected to deposition or erosion.
