ABSTRACT Water hammer in pressurized water hammer networks is one of the most critical aspects in the design and management of distribution systems. Sudden changes in flow rate, caused by the fast closure of a valve, the shutdown of a pump, or accidental events, generate pressure waves that propagate along the pipelines, producing overpressures and depressions that can be harmful to the structural integrity and reliability of the system. A correct analysis of transients is therefore essential not only to ensure the hydraulic operation of the network, but also to ensure adequate safety margins in exceptional operating conditions. The present work analyzes the transient behavior of a real water network, with particular attention to the propagation, reflection and interference effects of pressure waves at nodes and geometric discontinuities.
