SIMULATION BASED ON FINITE VOLUME METHOD OF THE ENTRAIMENT OF DEBRIS FLOW



Abstract:
The mountain hazards like snow avalanches, landslides, rock falls, debris flows all have strong destructive power which seriously threaten human lives and belongings. Therefore, it is necessary to study more about the happenings and developments of these disasters. Among the important and common features of the debris flow, the entrainment is the one that can increase the volume of debris flow and affects significantly the flow motion. These influences usually result in a more harmful and stronger destructive power. With the method of finite volume discretization, the numerical simulation of the entrainment process of debris flow is achieved in this paper. The influences of entrainment capabilities on the motion and deposition of debris flow are mainly studied. The typical engineering examples show and prove the stability and effectivity of numerical methods.
