The aim of the present research is the study of this debris flow event by means of pre and post-event topographical data, post-event direct surveys and its reproduction by modeling the physical processes associated to its occurrence. Following Gregoretti et al. For this reason, the availability of pre and post-event data becomes fundamental for a reliable understanding of the phenomenon, as for its reproduction by models.

This section concerns the reproduction of the dolomit phenomenon by models. Simulations were carried out using both the radar estimates and the observed rainfall depths. Geomorphometric assessment of spatial sediment connectivity in small alpine catchments.

About deposition, the large deposits at the confluence were not satisfactory reproduced due to missed local bed reproduction of the terrain in the pre-event DEM. The initial solid-liquid surge hydrographs were, then, routed downstream by means of a cell model. Morphometric controls and geomorphic responses on fans in the southern alps, new zealand.

Outdoor Research is combining metro decades of experience building highly dexterous, durable gloves with an innovative new material 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, Semi-quantitative method for the assessment of debris supply from slopes dolomjti river in ungauged catchments. Hyetograph of the rainfall depths from megeo rain gauge and the corrected radar estimates.

Channel network source representation using digital elevation models. Characterization of debris flows by rainstorm condition at a torrent on the mount yakedake volcano, Japan. About m fule the second confluences, the Ru Secco Creek is culverted to allow the joining of a slope ski on the right side with a chairlift located on the left side of the creek Figure 3b.

Deposition and erosion depths map for the two groups of reaches. To admire the splendid rocks dolomitiche of the Crystal mountain is essential to climb to St. Erosion and deposition are computed along the steepest direction, where the maximum value V max of the mean velocities contributing to the discharges Q k is attained.

The Arpav forecast is OK.

The comparison between the simulation results with the deposition-erosion depth map accounts for the reliability of the phenomenon reconstruction, that is the capturing of its main features.

After building the DEMs of all the contributing watersheds, needed for the hydrological simulations, pre and post-event topographical data were used for building the pre and post-event DEMs of the area affected by the occurred debris flow. 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 solid-liquid volume is given by the sum of the solid volume with the volumes of runoff contributing to debris flow and of the interstitial water of the entrained sediments as also proposed by Gregoretti et al. In the same Figure S2the exit of the culvert just after the event appears mainly free.

Ru Secco Creek origins downstream Forcella Piccola Fork and following a quasi straight route reaches the bottom of the Boite Valley where it crosses the village of San Vito di Cadore and flows into the Boite river. In summer, it’s often much more difficult for them to get it right as very often they’re trying to forecast thunderstorms caused by instability and they’re just dealing with probabilities as a percentage. In reply to davkeo: Srpav is divided in three subsections relative to the hydrological modeling, the solid-liquid hydrographs determination and the debris flow routing.

More details are in Boreggio et al. GPS points corresponding to the check dams are also used for the pre-event DEM because they remained substantially unchanged. This reach is in fact protected by check dams and the bed slope diminishes.

In Gregoretti et al. Figure 1 shows the plan view of the sub-basins that provided runoff and the routing paths. Experimental evidences and numerical modelling of debris flow initiated by channel runoff. Upper image a is the map of estimated deposition and erosion fjle the reaches I-III, while the image below b is that simulated.

In Figures 3a4 the debris thick layer covering the Ru Salvela and Ru Secco Creeks aboutm 3 according to the computations of section 3.

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. The mass conservation is stated by means of the meto equations of the mixture and of the solid phase, while the momentum conservation by means of simplified motion equations of the mixture after assuming equal velocities for both the solid and liquid phases according to Rosatti and Begnudelli The original law of Egashira and Ashida was adapted after eliminating the reasons for the equilibrium angle because it can lead to uncorrect results.

Empirical relationships for debris flows. Direct measurement of channel erosion by debris flows, illgraben, switzerland.

In the first case, the exact shape of pre-event debris deposit 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.

The small debris flow routed a new path on the reshaped slope, avoiding, the protection works. The pre-event topographical data provided the DEM for running the routing simulations. An approach for the evaluation of the risk of erosion of the biodiversity to level of community: The Supplementary Material for this article can be found online at: Clicca to open a window with a meteorological updating on the Venetian dolomitis.

The map of Figure 9 allows the computation of the sediment volumes deposited and entrained:
