IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Uncertainty Analysis of DO Concentrations in the Buffalo River Using the Perturbance Moments Method
Author : Christina Tsai and Mao Li
A three-point approximation method, the Perturbance Moments Method (PMM), is applied to quantify the uncertainty of predicted dissolved oxygen(DO) concentrations in the Buffalo river that arise from various sources of uncertainty, such as data variability and parameter uncertainty. Numerical investigations reveal that the overall uncertainty of the output DO concentrations does not necessarily equal to the sum of the uncertainties of all individual variables or parameters of interest. Therefore, different sources of uncertainty can have compensative or additive effects on the overall uncertainty of output DO concentrations. In a particular case study of the Buffalo River, the variability of measured concentrations was demonstrated to have the largest influence on the overall uncertainty of predicted DO concentrations.
