Abstract
Water distribution networks (WDNs) exhibit nonlinear hydraulic dynamics due to pipe friction, fluid inertia, and water compressibility. This paper evaluates the accuracy of linear and discrete time approximants of a benchmark nonlinear WDN, modelled using the Elastic Water Column (EWC) approach. For this benchmark, three types of approximants are used: a linear continuous-time model, a nonlinear discrete-time model, and a linear discrete-time model. These approximants are compared with the original nonlinear continuous-time model, using the following criteria: the Integral Absolute Error (IAE), the Integral Square Error (ISE), the Integral Time Absolute Error (ITAE), the Integral Time Square Error (ITSE), and the Infinity Norm Error (INE).
