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 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 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 کاملCritical conditions of bed sediment entrainment due to debris flow
The present study describes entrainment characteristics of bed material into debris flow, based on flume tests, numerical and dimensional analyses. Flume tests are conducted to investigate influences of bed sediment size on erosion rate by supplying debris flows having unsaturated sediment concentration over erodible beds. Experimental results show that the erosion rate decreases monotonically ...
متن کاملAcoustic module of the Acquabona (Italy) debris flow monitoring system
Monitoring of debris flows aimed to the assessment of their physical parameters is very important both for theoretical and practical purposes. Peak discharge and total volume of debris flows are crucial for designing effective countermeasures in many populated mountain areas where losses of lives and property damage could be avoided. This study quantifies the relationship between flow depth, ac...
