Bridge obstruction caused by debris flow: A practical procedure for its management in debris-flow simulations
نویسندگان
چکیده
Bridge clogging due to a debris flow is phenomenon scarcely studied but critical in hazard mapping the mountain area. Since rational and systematic approach still missing, we propose practical method deal with this numerical framework. We tested methodology by using, as model, two-phase, mobile-bed model TRENT2D and, site test case, village of Voueces north-west part Italian Alps. The application shows reasonable results highlights importance approach.

Assessing Debris Flow Hazard by Credal Nets
Debris flows are among the most dangerous and destructive natural hazards that affect human life, buildings, and infrastructures. Starting from the ’70s, significant scientific and engineering advances in the understanding of the processes have been achieved [4, 7]. Yet, human expertise is still fundamental for hazard identification, as many aspects of the whole process are poorly understood; a...
متن کامل[Research progress in post-fire debris flow].
The occurrence of the secondary disasters of forest fire has significant impacts on the environment quality and human health and safety. Post-fire debris flow is one of the most hazardous secondary disasters of forest fire. To understand the occurrence conditions of post-fire debris flow and to master its occurrence situation are the critical elements in post-fire hazard assessment. From the vi...
متن کاملInfluence of rheology on debris-flow simulation
Systems of partial differential equations that include the momentum and the mass conservation equations are commonly used for the simulation of debris flow initiation, propagation and deposition both in field and in laboratory research. The numerical solution of the partial differential equations can be very complicated and consequently many approximations that neglect some of their terms have ...
متن کاملSelecting a Temporary Debris Management Site for Effective Debris Removal
The overall debris removal after disasters is often prolonged due to the huge amount of debris and lack of capacities such as a Temporary Debris Management Site (TDMS) in the community. This results in a delay of overall recovery and increases the total recovery cost. Strategic planning and building a TDMS will help in providing extra time for proper disposal of debris and clearing a disaster-i...
متن کاملDebris Flow as a Mechanism for Forming Martian Gullies
The current low temperatures and pressures at the martian surface are not conducive to the stability of liquid water; hence the discovery of recently active, fluvial-like gullies [1, 2] presents an apparent paradox: how can these fluvial landforms have occurred if water is not stable at the surface? To approach this problem we have compared the morphometric properties of gullies in various sett...
