  报告摘要
  Debris flows that entrain sediment by undermining channel beds or scouring channel banks can become exceptionally mobile and destructive. Therefore, the calculation of entrainment plays an important role in debris flow runout analysis. An analytical entrainment model is proposed that takes into account surface erosional effects by considering progressive scouring and shear failure on the channel surface. To understand the entrainment process in granular flow, a flow channel was setup using a Discrete Element Method (DEM) model. The analytical entrainment model is also incorporated into a runout model to study an extremely large rock avalanche occurred on April 9, 2000 at Yigong Tibet, China. Measurements obtained from site investigation are used to verify the model.
