Abstract

Often the modelling approach is considered as a 'final' tool which is used when all the data are already collected in order to integrate all of them in the model. Another approach is to use simulations as an intermediate tool providing informations on the necessary data and investigations to be made in order to reach a better accuracy with regard to the real processes occurring in the aquifer. This methodology has been applied on a particular case study, involving a gallery of about 3 km length, collecting 900 m^/hour of drinking water in a chalky aquifer. Results of the simulations provi
