Random hydrologic data are used in frequency analysis to estimate the probability distributions and the parameters of hydrologic events. The estimated distributions and parameters, which are subject to uncertainty, are used in optimal risk-based design procedures to compute the expected damage cost. Therefore, the solutions from an optimal risk-based design procedure are also subject to uncertainty. This paper applies the bootstrap resampling technique to assess the degree of uncertainty of the optimal solutions from an optimal risk-based design procedure. The method was applied to the optimal risk-based design of pipe culverts.
