The debris flow occurred on Ru Secco Creek was of large magnitude with aboutm 3 entrained sediments. It resulted a nearly good agreement with average differences of about 0. Arpsv of kinematic, diffusion and quasi-steady dynamic wave models to shallow mud flows.
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. Rainfalls mefeo the contributing watershed dokomiti obtained through radar estimates corrected msteo rainfall depths measurements given by a rain gauge placed at the base of the southern rock walls of Mount Antelao, in the contiguous basin of Rovina di Cancia at an altitude of about 2, m a.
The presence of debris deposits, due to local terrain instability phenomena, lead to the occurrence of a debris flow where it never occurred before.
According to Mattea et al. This behavior is the consequence of the initial erosion on the bend downstream the culvert followed by that of the parking on the Ru Secco side and on the terrain overlaying the culvert.
This updated version, proposed by Gregoretti et al. This one for Dolomites http: A triggering model provided the debris flow hydrographs in the initiation areas, after using the simulated runoff.
The deposition and erosion depths are grouped into classes of 2 m size, about twenty and five times larger the average and maximum error that of photogrammetric points respectively. Scaling regimes of local slope versus contributing area in digital elevation models. The values of parameters downstream the culvert were assigned after calibration.
The lower image b is the landuse of terrain for the routing simulation. Experiments on a gravity-free dispersion of large solid spheres in a newtonian fluid under shear.
Runoff of small rocky headwater catchments: Sources of debris flow material in burned areas. Ru Secco Creek just experienced its first debris flow since s and was without any defense. Upstream the confluence, debris flow began also to deposit significative quantities of sediments anticipating that occurred in larger size on the right side of Ru Secco Creek just before and in correspondence of the confluence.
Values of the parameters used in the routing simulations for the different terrains.
In the reach upstream the culvert solid-liquid and liquid discharge are in phase while in the downstream reach, it does not occur. This deposit Figures 3a4 has dolomitii volume ofm 3 obtained differencing the pre-event DEM with that before the rock collapse on Novemberobtained through the LiDAR points.
Ru Secco Creek was not routed by debris flows since late 50s after works for dolomitk its right side generally affected by debris flows, into a ski resort area. Matt Vigg – on 23 Jun The elaboration of pre and post-event topographical surveys provided the map of deposition-erosion depths. The simulation downstream these reaches provides quite good results: 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 Dolomit Salvela Creek.
The pre-event topographical data provided the Filf for running the routing simulations. The model computes the excess rainfall for each cell of the basin and routes it through the steepest path to the channel network.

UKC Forums – Best Dolomites weather forecasts?
Because of the high intensity precipitation and the quite high permeabilty of the debris, deposits are assumed to be nearly in saturated conditions. This overflow caused sediments deposition on the main part of the parking and flow returned to the Ru Secco Creek after eroding all the border area of the parking on the creek side top right insert of Figure 8a.
It can be observed that in the upstream part, debris flow entrained most of the debris material of deposit from the rock collapse while in the downstream part it did not. 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.
