This article proposes a four-staged method for a debris-flow hazard analysis which includes design volume assessment, determination of the hydrograph for predefined return periods, numerical simulations to predict the spatial distribution of deposits. A final hazard map, with the delineation of low, medium and high hazard is obtained combining the different hazard classes of the individual rheology-specific hazard maps. This hazard analysis includes both the concepts of intensity and probability of occurrence of debris flow, proving that the use of hydrological analysis implements complex forecasting methods by combining the output data obtained by numerical models.
