Abstract: This paper shows how pipe replacements and control valve installations can be optimized in water distribution networks to reduce leakage, under minimum nodal pressure constraints. To this end, a hybrid multiobjective ...

Abstract: This paper deals with two-phase flow models of transient cavitating pipe flow, showing how bubble-flow models and shallow-water models can be considered in a unitary framework by only changing the geometry of the cross ...

Abstract: Transients in pressurized polymeric pipes are analyzed by means of a two-dimensional (2D) Kelvin-Voigt viscoelastic model, calibrated by means of a microgenetic algorithm on the basis of pressure traces. The reliability ...

Abstract: Traditionally, the design and the rehabilitation of water distribution networks (WDNs) have been addressed as separate problems. Here, a comprehensive approach to address both the design and rehabilitation of WDNs is ...
