Abstract

Typical distribution system network model calibration approaches adjust roughness coefficient values to match observed pressure and supervisory control and data acquisition (SCADA) equipment data assuming known user demands. Pressure data alone, however, do not contain information related to hydraulic residence time and travel path, making such data less useful for calibrating both the hydraulic and water quality portions of a distribution system network model. This study presents a network-wide dual-tracer field-scale study, coupled with water quality monitoring, to collect a rich data set for evaluating hydraulic and water quality issues. The raw data illustrate the path-specific information that can be generated beyond the use of pressure measurements alone. The observed data are used to minimally calibrate a distribution system model that is provided by the utility, and illustrates the use of tracer data for providing confidence with respect to the predictive ability of the network model. Additional considerations related to automated calibration techniques and the potential benefits of more accurate distribution system models are discussed.
