Hydraulic network simulation models are widely used by planners, water utilitypersonnel, consultants, and others involved in the analysis, design, operationand maintenance of closed-conduit hydraulic systems. Quite possibly the largestapplication of hydraulic network models lies with the municipal water supplyindustry. The results of network models have been used to assist in long-rangemaster planning , short-term project design, fire flow studies, daily operations,emergency response, energy management, and rehabilitation, among others. Clearly,multi-million dollar decisions can be based on the results provided by hydraulicnetwork models. Consequently, the results from the model must bear closeresemblance to the actual performance of the hydraulic system. In other words,the computer model must be calibrated. The purpose of this paper is to presentguidelines for network model calibration. The degree of accuracy needed for modelcalibration is discussed within the context of the intended use of the model. Forexample, a higher degree of calibration is necessary for a model that is used toexamine daily operations than is needed for a model used in long-range planningstudies. The paper also discusses calibration approaches and testing proceduresthat can be used to aid in the calibration effort. Includes 7 references.
