Hydraulic designs are subject to uncertainties due to randomness of natural phenomena, data sample limitations and errors, modeling reliability, and operational variability. Uncertainties can be measured in terms of the probability density function, confidence interval, or statistical moments, such as standard deviation, or coefficient of variation, of the stochastic parameters. Analysis of parameter uncertainties is essential for a satisfactory reliability analysis of a hydraulic design. In this paper, several methods that are useful for uncertainty analysis in hydraulic design are briefly introduced. They include first-order variance estimation method, Rosenblueth two-point procedure, simulation, and integral techniques.
