A mathematical model is proposed to determine hazard zone of debris flow and debris deposition. Two layer high concentrated model of solid transport is used in cooperation with continuity equation of solid phase for determination of deposition in the model. Transition from supercritical flow to subcritical flow exist from mountainous stream to flood plain. The proposed model simulated well such transition. Here, the simulated deposition bed are compared with experimental ones to verify the model. Simulated results show fairly good agreement with experimental results. The flow properties and deposition of debris flow in the flood plain can also be calculated by suggested model. The optimum value of the parameter α (the parameter of the solid transport equation) is found to be around 0.13 for determination of deposition of debris flow. Simulated deposition and debris flow surface cap be used to determine hazard zone and simulated flow velocity may be applied to decide hazard risks of different areas. In this respect, the hazard zone of debris flow and its deposition can be determined in the different flow conditions of debris flows.
