Abstract: Modelling water quality in distribution networks is essential for detecting contamination, but currently simplified models are used that neglect diffusion and dispersion. The Peclet number, previously used to evaluate the suitability of one-dimensional advective transport without compromising model accuracy, has been shown to be ineffective for two-dimensional advective-dispersive modelling in real systems. The present study aims to determine a new indicator: to discriminate the dominance of the advective-dispersive process, to have a rapid decision-making tool capable of establishing a priori the behaviour of the distribution network, to use the numerical model more for water quality modelling.
