DigitalWaterMassCalibration

The mass calibration approach allows to calibrate hydraulic network models that incorporate existing DMAs based on the concept of mass balance, which separates the deterministic component (i.e., volumetric leakages) from the stochastic demand component (i.e., water request of consumers). Hence, this allows to identify the demand pattern and the parameters of the pressure-dependent background leakages model. It allows to visualize the calibrated customers’ demand and linear leakage index (M1a) patterns, as well as the linear leakage index (M1a), the average pressure from the model (AvgPress), the asset management indicator (C) as the ratio M1a/AvgPress and key DMA features.
