AWWA JAW68590

A hydraulic network model provides an importantperspective on water system performance that is simplyunavailable by any other means. Through mathematicalsimulations, a model can provide information aboutpressures and flows both for locations that are notreadily accessible and for scenarios that have not yetoccurred or that occur with low frequency and highconsequence.However, some of the input parameters required forhydraulic network modeling are not knowable with ahigh degree of accuracy. The temptation to adjust theseparameters so that model results match commonlyavailable field data cannot be justified mathematicallyand should not be considered for calibration. The reconciliationof model results and field data may includea sensitivity analysis of input parameters and the considerationof possible network anomalies, such asclosed valves. The techniques recommended here canallow for more effective use of a model within theinherent limitations of input accuracy. Includes 9 references, table, figures.
