A corrected smooth particle hydrodynamics method for the simulation of debris flows

This article presents the development and application of a corrected smooth particle hydrodynamics (CSPH) code to the simulation of debris flow and avalanches. The advantages of a mesh-free method over other traditional numerical methods such as the finite element method are discussed. A new frictional approach for the boundary conditions and modified constitutive equations are introduced in the SPH method. The resulting technique is then applied for the simulation of debris flows, comparing the results with those obtained from experiments reported by other researchers. (C) 2003 Wiley Periodicals, Inc.
