Abstract: The stochastic analysis of radionuclides migration through groundwater is approached by means of the study of multiple paths corresponding to multiple simulated transmissivity fields. In order to obtain travel times and trajectories as realistic as possible, the simulated fields have to be conditioned to all available data that can be related with this param eter. The analysis is ap plied to a synthetic case in w hich it is assum ed that only some limited inform ation is available, obtained from a fully known fictitious transm issivity field and its corresponding piezom etric head field. This provides a reference for judging the quality of the probabilistic results obtained. The present work studies the contribution of a secondary variable obtained from a geophysical survey and known along several hypothetic seismic lines and its comparison with the improvement provided by piezom etricdata. It is concluded that a big amount of secondary inform ation allows to reproduce the m ain features of the reference transmissivity field and im proves the m ass transport problem prediction. H ow ever, with far less m easurem ents of piezom etric head it is possible to obtain an even better and more realistic probabilistic characterization for radionuclides migration problems
