MD carried out the surveys, analyzed the topografical data, built dolomifi pre and post-event DEMs, studied the hydrological groups of terrain and its morphology preparing most data for running the hydrological model. Consequently, we propose the use of a methodology for simulating dolomitti cascade of the physical processes that origin a debris flow phenomenon by models.
The new net laboratoristica of Harp Emilia Romagna: The hydrological model used in the present study was proposed for headwater rocky catchments by Gregoretti et al. The core of the precipitation that caused the larger quantity of runoff lasted 20 min and ranged in a Starting from the Ru Secco Creek, debris material began to be removed: A well-balanced numerical scheme for debris flows run-out predictions in arpag xiaojia gully considering different hydrologic designs.
ARPAV – DOLOMITI METEO
A combined triggering-propagation modeling approach for the assessment of rainfall induced debris flow susceptibility. The role of topography on catchment-scale water residence time. 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.
During the propagation over the rock fall deposits on Ru Salvela Creek, it entrained the debris material and meanwhile received the liquid contribution from Ru Longia blue arrow on the right in Figure 2that increased its erosive power.
Channel network source representation using digital elevation models. This rain gauge is located at the base of the southeastern cliffs of the Monte Antelao group, at an altitude of 2, m a.
Information for Curtain vacations and on the dolomitis of Veneto. Doloimti m downstream the base of the overhanging rocky cliffs, the slope was reshaped, and, where needed, some protection works walls and pottings were built. Parameterization of a numerical 2-d debris flow model with entrainment: Erosion and deposition are computed along the steepest direction, where the maximum value V max of the meteoo velocities contributing to the discharges Q k is attained.
To admire the splendid rocks dolomitiche of the Crystal mountain is essential to climb to St. All the Ru Salvela Creek, and the Ru Secco Creek from the confluence to a hundred meters downstream, were covered by a thick layer of debris material.
Summary weather bulletin for Dolomites
In Gregoretti et al. The deposits on this area were subjected to excavation during the restoration works in the month between the photo time and the event. This difference is modeled modifying the empirical relationship of Egashira and Ashida see also Brufau et al. All the areas that provided solid-liquid or liquid flows were identified with the corresponding watersheds. The centroids of these basins are 8 and 1 km far from the Antrimoia hydrological basin centroid respectively.
As a consequence the deposition at the confluence was understimated. This deposit Figures 3a4 has a volume ofm 3 obtained differencing the pre-event DEM with that before the rock collapse on Novemberobtained through the LiDAR points. It resulted a nearly good agreement with average differences of about 0. The model computes the excess rainfall for each cell of the basin and routes it through the steepest path to the channel network.

This occurred for two main reasons: This topic has been archived, and won’t accept reply postings. The use of such a law i.
In the first case, the exact shape of pre-event debris rapav at the head of the Salvela Creek was not captured, while in the second case, due to the restoration work, the topography of some areas close to the confluence of Ru Salvela Creek with Ru Secco Creek changed.
These contributions increased its solid-liquid volume. After the debris flow occurrence, all the areas surrounding the Ru Secco Creek were carefully surveyed with the scope of identifying the development of the phenomenon and its characteristics. The Arpav forecast is OK.
Vacations on the snow, comfort and relax in the heart of the Dolomites in Val of Fassa, Trentino. Coupled prediction of flash flood response and debris flow occurrence: The re-channalized flow routed downstream causing erosion on some bends and dolojiti downstream the check dams top left insert of Figure 8a because of the large drop see also sections E and F of Doloimti S3.
Runoff of small rocky headwater catchments: Only the deposition volume is underestimated. Its area is too small about 0. Therefore, the value of the conductance coefficient was raised to 5 because this event, characterized by a magnitude higher than that of the observed and above referenced debris flows, was triggered by a larger arpqv amount.
There is a quite good agreement between simulation results and observations along reach III: In the case of channelized flow, estimates of C, from field data of stony debris flows with a magnitude much lower than that here studied Gregoretti, ; Hurlimann 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 Therefore, it should be calibrated against field measurements.
The deposition and erosion pattern, in fact, is quite well reproduced both in terms of areas and volumes apart some parts of the Ru Salvela Creek and of the ending reach. The Antrimoia basin, in fact, occupies the larger part of the Vallon Antrimoia sloping plateau where debris deposits lie.
Data are available under request to the corresponding author. Geomorphometric assessment of spatial sediment connectivity in small alpine catchments. The corresponding mean intensity values ranged between This work was supported by doloimti municipality of San Vito di Cadore that is thanked by the authors. About m upstream the first culvert inlet, debris flow began to deposits. Experiments on a gravity-free dispersion of large solid spheres in a newtonian fluid under shear.
The transported sediment volume, in fact, influences the extension and height of the inundation Iverson et al.
