The presence of excavator tracks and flat areas due to the debris deposits reworking could have significatively conditioned the local routing simulation.
Top right insert shows the debris material covering the Vallon d’Antermoia rocky surface at the base of the collapsed cliff flight of 1 July This is coherent with the initial moderate solid discharge peak in cross-section E Figure For these reasons, the properties and the characteristics of the debris material are assumed to be quite the same. According to Mattea et al.
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.
Sediment budget monitoring of debris flow and bedload transport in the manival torrent, se france. The channel network cannot be provided by cells with a drainage area larger than 0. This threshold value was successfully tested by Gregoretti et al. This value was also confirmed by the field observations of Jordan Gis-based cell model for simulating debris flow runout on a fan. The uniform flow Equation 4 can be straightforwardly derived by integrating along the flow depth the dispersive normal stress given by Bagnoldtypical of a grain-collision dominated rheology that rules the stony debris flows dynamics Takahashi, Objective delineation of lahar-hazard zones downstream from volcanoes.
Using the rainfall estimated by weather radar and corrected by the nearest rain gauge, about 0. No use, distribution or reproduction is permitted which does not comply with these terms. Filf the conductance coefficient, Crespect to Gregoretti et al.
Its area is too small about 0. The use, distribution or reproduction in other forums is permitted, provided the original author s and the copyright owner s are credited and that the original publication in this journal is cited, in accordance with accepted academic practice. A geomorphological analysis was initially carried out after surveying the dolimiti basin.
Evaluating the influence of gridding techniques for digital elevation models generation on debris flow routing modelling: Kean – on 25 Jun An explicit scheme is used to solve numerically the model equations with the time step computed according to the Courant-Friedrichs-Lewy stability condition. These results were used for identifying the watersheds where modeling runoff and solid-liquid hydrographs as well the debris flow routing.
This analysis provides a guide for the implementation of the models simulating the physical processes concurrent to its development as well as the initial conditions. Figure S6 shows the results of the two methods. The peak solid-liquid discharge, Q Pis computed following the relationship provided by Lanzoni et al.
This topic has been archived, and won’t accept reply postings. Section 5 discusses the results and, finally, section 6 reports the conclusions.

The main triggering factor of the Ru Secco debris flow was a large rock collapse on the northern cliffs of Mount Antelao occurred the previous autumn. Flie can login by mefeo one of your existing accounts. Bottom right insert shows the Ru Salvela creek covered by debris material till the confluence with Ru Secco creek that was obstructed picture taken on November Modeling of debris flow depositional patterns according to the catchment and sediment source area characteristics.
Upstream the culvert, the bottom is in general raised up respect to the pre-event situation. New Topic Reply to Topic.
Sediment volume that did not deposited there during simulation, in fact, deposited just downstream the confluence beginning of reach III. In the present case, the inaccessibility of the triggering site prevented direct measurements, and the unit width triggering discharge was estimated as 0.
