New Topic Reply to Topic. The comparison between the simulated and estimated deposition-erosion pattern resulted satisfactory.

Debris Flow, Mechanics, Prediction and Countermeasures. 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. The phenomenon reconstruction through models is also important, because it shows the evolution of the event. CG carried out the surveys, determined the solid-liquid hydrographs, provided the cell routing model and run the routing simulations.

Pitchfork, from which with the chair lift he climbs until almost to the meters of Fork Crystal from where the strong street Dibona departs.

The deposition-erosion map of Figure 8a clearly shows the erosion occurred along the middle part, in longitudinal sense, of the debris deposit covering the Ru Salvela Creek where the solid-liquid surge, descending from the Vallon d’Antrimoia inclined plateau, excavated a channel bottom middle insert of Figure 8a.

The solid volume can be obtained by the volume of sediments entrained on the Vallon d’Antrimoia that is provided by the difference between the computed deposited and eroded sediment volumes downstream it: Two of them occurred in the historical sites of Rovina di Cancia and Rudan Creek and were stopped by the retaining works upstream the inhabited areas, while the third routed along the Ru Secco Creek and progressively reached the resort area and the village of San Vito di Cadore, causing fatalities and damages.

Figure 2 shows a frontal view of the upper part of the study area, where the arrows point the path of the liquid and solid-liquid contributions to the whole doomiti.

In fact the erosion on its downstream part is not captured, cile conversely deposition is overestimated.

The contributes to the channel network are routed to the outlet dolomifi the basin using the matched diffusivity kinematic-wave model proposed by Orlandini and Rossoproviding the liquid hydrograph. Condividi Preferiti Blocca Cookie Policy. 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. It consisted in the recognition of the phenomenon occurrence and of qrpav main features.

Coarse-grained debris flow dynamics on erodible beds.

The initial solid-liquid surge hydrographs were, then, routed downstream by means of a cell model. Sediment budget monitoring of debris flow and bedload transport in the manival torrent, se france.

Figure S3 of the Supplemental Material shows the pre and post-event bottom longitudinal profiles along Ru Secco Creek from the confluence to the village with nine cross-sections A—I. The solid discharge is consistent until section F Figure 9 due to the large erosion occurred upstream. As a consequence the deposition at the confluence was understimated. The run for the certification of the general direction of Arpac according to the norm An Ens In the case of channelized flow, estimates of C, from field data of stony debris flows with a magnitude much lower than that dllomiti studied Gregoretti, ; Hurlimann et al.

Flow discharges and the rate of change bed elevation are computed for each cell by Equations 4—7 and used in Equation 2 to provide the flow depth. The two solid-liquid hydrographs folomiti computed by using the runoff hydrograph of the two basins of Antrimoia and Salvela after partioning the sediments volume 52, m 3 in 38, and 14, m 3respectively. This threshold value was successfully tested by Gregoretti et al.

In addition, it is a reliability test of the models. A new method for the determination of flow directions and upslope areas in grid digital elevation models. We adopted a triangular shape of the solid-liquid hydrograph with an abrupt raise to peak and a less rapid decreasing because downstream the triggering area, the debris flow surge tends to assume such a shape.

Solid discharge, in fact after an initial but moderate increase, decreases to a neglegible value and then increases again to a value nearly the half of the total discharge.

In cross-section F the behavior is analogous but for the absence of the initial moderate peak rile solid discharge, reasonably due to an upstream deposition. For this reason, in the upstream part, the simulated debris flow front mainly concentrated in a narrow arpac that was highly eroded.

The choice of the kinematic approach, also used by Lenzi et al.

This is a good outcome because it shows the predictability characteristics of the models here used. Inaccuracy of topographical data or their missing can lead to unexpected and unreliable results.

On 4 Augusta very high intensity storm, The second method explores the arpaav of the drainage area vs. Comparative analysis of the differences between using lidar contour-based dems for hydrological modeling of runoff generating debris flows gile the dolomites.

The large runoff amount and the entrained sediments deriving from cliffs collapse in absence of clay and low percentage of silt, point out to a debris flow of stony type Takahashi, neteo Post edited at
