In Gregoretti et al.

Closure relations for mobile bed debris flows in a wide range of slopes and concentrations. Figure 3a shows the situation about 1 month before the occurrence of the debris flow event with the works for reducing the large debris deposits on the Ru Salvela Creek. Please note that also Hussin et al. 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 Parameters adopted in the hydrological model.

Sediment volume that did not deposited there during simulation, in fact, deposited just downstream the confluence beginning of reach III. Relevance of erosion processes when modelling in-channel gravel debris flows for efficient hazard assessment.

Figure 6 shows the rainfall depths sampled at 5 min by the rain gauge with those of the corrected radar estimates for each of the five considered hydrological basins.

Following Gregoretti et al. MBe helped in the pre and post-event DEM building, provided the hydrological model and run the hydrological simulation, contributed to the solid-liquid hydrographs determination prepared the file data for running the routing simulations, helped in run the routing simulations, analyzed the results, made figures.

Parameters of debris flow routing simulation depend on the terrain channel, scree, grass, wood and slope because flow resistance and deposition-entrainment processes vary with them. The values of parameters downstream the culvert were assigned after calibration.

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 Crux Expedition Award is an annual grant to encourage young climbers to try for adventurous objectives. The run for the certification of the general direction of Arpac according to the norm An Ens View of the area subjected to deposition or erosion and land use.

Inaccuracy of topographical data megeo their missing can lead to unexpected and unreliable results. The comparison between the simulated and estimated deposition-erosion pattern resulted satisfactory.

The transported sediment volume, in fact, influences the extension and height of the inundation Iverson et al. Hydrogeomorphic processes in a steep debris flow initiation zone. Direct measurement of channel erosion by debris flows, illgraben, switzerland. For the reach V, the agreement is not so satisfactory both for the volumes and the areas.

Ru Secco Creek just experienced its first debris flow since s and was without any defense. In reach I that of Ru Salvela creekthe simulated eroded sediment volume quasi coincides with that estimated but it is more concentrated in the upstream part of Ru Salvela.

Arabba In the heart of the Dolomites, among the Footstep Pordoi and the Campolongo, offer afoot unforgettable vacations absorbed in the green of the mountains, walks and excursions and in mountain bike. 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, Condividi Preferiti Blocca Cookie Policy.

ARPAV – DOLOMITI METEO

The debris flow occurred on Ru Secco Creek was of large magnitude with aboutm 3 entrained sediments. The remainder of this paper is organized as follows. The geomorphological analysis is essential for understanding whichever gravitative mass movement on earth, and allowing its reliable reproduction by models. This volume is increased to 52, m 3 to consider the sediment volume that reached the Boite River see the previous section.

We will be provided with an authorization token please note: Therefore, some path and the flat area built by the excavators, that we could not to reproduce, could have significatively conditioned the flow routing.

UKC Forums – Best Dolomites weather forecasts?

Furthermore, the satisfactorily results obtained in the reproduction of the phenomenon suggest that a reliable reproduction of an occurred debris flow should be based on four factors:. Topographical data are given by two LiDARs flights held on November andthe photogrammetric restitution of photos of the large debris deposit taken 1 month before the event, a drone photogrammetric flight held 2 days after the event and direct GPS survey held about 2 months after the event.

Experimental evidences and numerical modelling of debris flow initiated by channel runoff.

This means that the debris flow discharge, and thus the magnitude of the debris flow, increases with the amount of the runoff generating the event, while the flow resistance decreases. The simulation in the upstream reaches of Ru Salvela and Ru Secco Creeks is conditioned by pre-event local topographical data that are partially inaccurate and missing metdo.

This zone is just under the cliffs and some three dimensional shapes of debris deposits could be not detectable by the photos by which the pre-event DEM has been built. The entrained and deposited sediment volumes were estimated through the deposition-erosion depths map Figures 8a9 that was obtained differencing the pre and post-event DEMs. The median of the errors was equal to 0.

Comparative analysis of the differences between using lidar contour-based dems for hydrological modeling of runoff doomiti debris flows in the dolomites. Data are available under request to the corresponding author.

The fallen debris material deposited on the Vallon d’Antrimoia inclined plateau at the base of the collapsed cliffs and, below it, on the Ru Salvela Creek, covering it from the head to the confluence with the Ru Secco Creek.
