Pressure-dependentleakage Splittingmethod p-Laplacian Newtonmethod a b s t r a c t The objective of this paper is to present and validate an improved formulation of the hydraulic network equations that incorporate pressure-dependent leakage in Water Distribution Systems. The formulation is derived from the NavierStokes equations and solvedusinganadequatesplittingmethod.Animplicitnumericalschemeisusedtosolve thep-Laplacianequation.Themodelisvalidatedonabenchmarkpipenetwork. ’2009PublishedbyElsevierLtd
