Influence 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 کاملAssessing 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 کاملExperimental study on the rheological behaviour of debris flow
A model able to describe all the processes involved in a debris flow can be very complex owing to the sudden changing of the material that turns from solid into liquid state. The two phases of the phenomenon are analysed separately referring to soil mechanics procedures with regard to the trigger phase, and to an equivalent fluid for the postfailure phase. The present paper is devoted to show t...
متن کاملSystems and Sensors for Debris-flow Monitoring and Warning
Debris flows are a type of mass movement that occurs in mountain torrents. They consist of a high concentration of solid material in water that flows as a wave with a steep front. Debris flows can be considered a phenomenon intermediate between landslides and water floods. They are amongst the most hazardous natural processes in mountainous regions and may occur under different climatic conditi...
