Preface

In recent years, the increasing impacts of landslide hazards on human lives and life-line facilities worldwide has advanced the necessity to find out both economically acceptable and useful techniques to predict the occurrence and destructive power of landslides. Though many projects exist to attain this goal, the current investigation set out to establish an understanding of the initiation and propagation mechanisms of landslides via numerical simulations, so that mitigation strategies to reduce the long-term losses from landslide hazards can be made. This book summarizes some of the recent researches on landslides via the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD). These two methods have been used to investigate the mechanical and hydraulic behaviour of granular ma
