Summary A class-A prediction of debris flow impact against rigid obstacles is presented in this paper. The granular material, defined as the non-Newtonian fluids, is described by the Bingham model. A case of the three-dimension dry granular flow down an inclined channel is simulated by the weakly-compressible SPH method. Features such as particle accumulation, the interface between inflows and quasi-static regimes during flow are well-captured.
