Abstract
Equations for debris-flow discharge contain hydro-geological and topographical parameters. Considering the uncertainties of the parameters and using the first-order second moment method (FOSM method), this paper has developed a probabilistic equation of debris-flow discharge. The sensitivity of each parameter in this equation is analyzed, and the relationship of the design debris-flow discharge with the coefficient of variation of parameters, the safety probability and the rainfall return period are also discussed.
