Evaluation of Reliability Indicators for WDNs with Demand-Driven and Pressure-Driven Models
Liserra, Tonino; Maglionico, Marco; Ciriello, Valentina; … - In: Water Resources Management 28 (2014) 5, pp. 1201-1217
Reliability of water distribution networks (WDNs) has received much attention in recent years due to progressive aging … of infrastructures and climate change. Several reliability indicators, focusing on hydraulic aspects rather than water … quality, have been proposed in literature. Reliability is generally assessed resorting to well established methods coupling …

Optimal Operation of Pressurized Irrigation Networks with Several Supply Sources
García, I. Fernández; Díaz, J. Rodríguez; Poyato, … - In: Water Resources Management 27 (2013) 8, pp. 2855-2869
The evolution of water distribution systems to pressurized networks has improved water use efficiency, but also significantly increased energy consumption. However, sustainable irrigated agriculture must be characterized by the reasonable and efficient use of both water and energy. Irrigation...

Local and Global Leak Laws
Ferrante, Marco; Meniconi, Silvia; Brunone, Bruno - In: Water Resources Management 28 (2014) 11, pp. 3761-3782
The relationship between the functioning conditions of pipe systems and the leakage, or leak law, can be used at two different scales. At a local scale, i.e. for a single leak, it is derived from the classical orifice equation and, basing on experimental data, is modified to take into account...
