Abstract: From a linearized form of the equations of unsteady (transient) motion in an open channel of uniform cross section using the well-known technique of the characteristic lines, it is shown that under a set of not-too-restrictive ...

Abstract: This paper presents the energy audit of a water network, which is obtained from the energy equation in integral form, and its time integration extended over a given period (day, month, or year). The analysis allows accounting ...

Abstract: Presented herein is a methodology for evaluation of water losses based on discrimination of the two components of uncontrolled water in a water distribution network: physical losses in mains and service connections, and ...

Abstract: Assuming 1D flow in pressurized systems, transient analyses can be performed using a number of well-established models. In the short-term timescale, practical problems are solved using either elastic or rigid models, whereas ...

Abstract: When a problem of hydraulic transients with entrapped air in pipelines and/or with water‐column separation is tackled, the variation of the length of the liquid column is not usually taken into account. In this paper (due ...

Abstract: The analysis and modeling of water distribution networks has been a well established engineering field for many years. However, important questions remain concerning the correct assessment of the spatial and temporal ...

Abstract: Aligned with the goals of achieving higher sustainability in water systems, the minimization of energy costs is a top priority for the operators and owners of such systems. Early research contributions on the rate of energy ...
