The assessment of debris flow hazards with Debris-2D of houses and buildings of citizen is presented. The worst scenario of hazard is considered. The input of mass volume and distribution is determined using map of landslide susceptibility. The water input is referred to the daily accumulative rainfall in the past event. We conduct calibration test of rheological parameter, i.e., yield stress. The simulation results show that debris flow has potential impact on the houses and buildings near mountain.
