The identification of pipe roughnesses in a water distribution network is formulated as nonlinear system algebraic equations which turns out to be demanding solve under real-world circumstances. This paper proposes an enhanced technique numerically this problem, extending the conventional Newton–Raphson approach with second-order derivatives determination search direction. Despite requirement e...

The knowledge of the simultaneous nodal pressure values in a water distribution network (WDN) can favor its correct management, with advantages for both utilities and end users, guarantee higher sustainability use resource. However, monitoring all nodes is not feasible, so it be useful to develop methods that allow us estimate whole field based on data from limited number nodes. For this purpos...

Cities rely heavily on the services provided by water distribution networks. These networks are large and complex, consisting of thousands kilometres buried pipes dozens facilities where is treated, pumped stored. Infrastructure managers entrusted with planning execution interventions these assets to ensure that service exceeds minimum levels mandated stakeholders at all times. This a difficult...
