Probabilistic Zoning of Hydraulic Performance of Water Distribution Network by Applying Key Parameter Uncertainty

Generally, the modeling of the Water Distribution Networks (WDNs) is done by the conventional methods that cause the outputs of the network are normally deterministic value by assuming certain inputs and parameters. But, in real ones, there are many uncertainties in model parameters. which causes, the results obtained by the conventional methods may not be satisfactory in practice, Therefore, the variation of key parameters in WDNs such as pipe roughness and diameter and also nodal demand can change nodal pressure and pipe flow that affected the performance of the network. However, by understanding the parameter uncertainties and how the uncertainties affect the accuracy of the model, the decision-makers can make the best decision that can prevent the WDNs from the unreliable events.
