Abstract: The latest report by the Smart Water Networks Forum (SWAN) showed that most of main capitals of the world have a level of non-revenue water greater than the maximum 25% recommended by the International Water Association (IWA). There is still no consensus in the literature of universal equations that can be used to quantify and detect water leaks, so more experimental and numerical studies need to be carried out. A systematic literature review conducted based on the Web of Science database indicated that the variation of the discharge coefficient (Cd), presented below in the Torricelli equation, is usually neglected in hydraulic leakage models. Despite this, recent experimental studies indicated a dependence of this coefficient on geometric, hydraulic, and hydrodynamic parameters (Shao et al., 2019; Yu et al., 2019). Then, this work aims to study the variation of the Cd with the above parameters through computational fluid dynamics (CFD). Q = Cd. A. (2g. H) 1/2
