Summary on Grant Application Form
Water distribution is the driving force behind many activities in the water industry and central to this is the efficient management of water distribution systems. Whilst the hydraulic performance of a distribution system is related to the magnitude of demands, the extent to which these demands are satisfied is dictated by the available heads. Therefore, what governs the behaviour of water distribution systems is pressure, not demand. Thus leakage, bursts, levels of service, fire-fighting and reliability problems are all manifestations of this.Although computer models to simulate performance are now used in all aspect of water distribution management, these demand-driven models have outlived their usefulness in that they work best only in normal operating conditions. Many critical operational scenarios involve subnormal operating conditions and to simulate these in a realistic way a new approach is needed. This project will develop a new generation of head-driven analysis methods which give pressure primacy. An innovative ouflows-adjustment and equilibrium-restoration technique is proposed. The proposed research is a collaboration between academia and industry involving theoretical, computation and practical aspects including verification and validation with data from real systems. New numerical methods and a prototype head-driven analysis software will thus be developed for practical application.
