Water Distribution Network's Modeling and Calibration. A Case Study based on Scarce Inventory Data

This paper focuses on modeling and calibration of a small and poorly documented (portion of the) water distribution network (WDN) that shows pressure problems. Field campaigns are conducted to reduce the inaccuracies found in the inventory's drawings and to aid building a first WDN model. A trial and error procedure was then used to produce successive refinements for the desirable WDN's model fit. The paper describes the path followed through the first model to the final calibrated model, including WDN's instrumentation, the definition of network zones and the measures taken to deal with the pressure problems.
