Governing equations for 2-D debris flow are physically divided into two steps: an advection step and a propagation step. The ADI factorization operation is performed to split each step scheme into one-dimensional equations. The difference operators in the equations are discretized by the finite volume method and this yields equations having coefficients in tridigonal matrix forms. The Bingham model is used to express the rheological behavior of debris flow. The routing model was used to simulate debris flow in inclined channels having a constant bottom slope as well as a gradually varying slope, and over an inclined plane.
