Estudio regional de las características hidrodinámicas y condiciones de flujo de manantiales de acuíferos kársticos existentes en el País Vasco

Resumen

In Chis study, different methods of statistic analysis have been applied to the time series from twenty representative exurgences of the main carbonated aquifers at the Basque Country. Thus, after having established the distribution mode of the information at the different discharge data groupsby the use of box plots, the techniques of the correlation and spectral analysis have been applied to the discharge and precipitation chro- nologic series, what has allowed to describe the behavior of the hydrogeologic systems, in addition to compare them. Later, the knowledge about the basic structure of the discharge series has been deepened, identifying the deterministic and residual components of the series and verifying the residual component to comply with the condition of second arder stationarity. The results obtained show that the methods used allow to characterize satisfactorily the unequal reply grade of the analysed units with different external canvassing and facilitate the establishment of some basic criterions which would make easy the choice of the most adequate modelization technique for the reconstitution of the unloading hidrographs in the future.
