Abstract: End-uses at water supply systems typically follow a random pulse behavior, which blurs as consumptions are aggregated upstream, affecting flow rate variability along the spatial scale. Instantaneous variability has impact ...

Abstract: Water demands are the main random factor that conditions flow variability within drinking water supply systems. The importance of using high-resolution demands in distribution mains is already well known, but there is ...

Abstract: Hydraulic state estimation (HSE) can be used to infer the flow and pressure regime in water supply systems based on the available measurements in the network and the associated hydraulic model. Because the inputs involved ...

Abstract: Droughts may be represented by two main characteristics—duration and severity. In this paper, a general methodology to evaluate the frequency and risk of the occurrence of droughts is presented using a bivariate drought ...

Abstract: Sanitary sewer overflows (SSOs) are becoming of increasing concern as a health risk. Utilities and regulators have taken preventive measures but many overflows still occur and are not identifiable, especially in access-challenged ...

Abstract: State estimation (SE) techniques are being applied to different network systems in order to convert system measurements into real information about the network state. SE applications to water systems are relatively novel, ...

Abstract: The drought frequency index (DFI) is employed in this study as a drought indicator and as a trigger mechanism for multireservoir system operations during drought. The DFI characterizes droughts according to their duration ...
