Abstract (English): In order to quantify the quality of the rainfall/discharge relationship across time-scales, we propose the use of both orthogonal wavelet multiresolution analysis and cross-correlation analysis. By using the two techniques together, it is possible to show, scale-by-scale, the influence of the input to the system (rainfall) on the response (discharge) of the aquifer and also to relate these results to the internal structure of the aquifer and to the degree of organisation of the karst drainage. An application of this method to three Pyrenean karsts is also shown. To cite this article: D. Labat et al., C. R. Geoscience 334 (2002) 551–556. [Copyright &y& Elsevier]
Abstract (French): Afin de quantifier le degre´ de causalite´ de la relation pluie–de´bits a` travers les e´chelles de temps, nous proposons de coupler analyse en ondelette orthogonale multire´solution et analyse corre´latoire croise´e. L'utilisation conjointe de ces deux techniques permet effectivement de rendre compte, e´chelle par e´chelle, de l'influence de l'entre´e du syste`me (pluies) dans la re´ponse de l'aquife`re karstique (de´bits) et, ainsi, de mettre en relation ces re´sultats avec la structure interne du syste`me et son degre´ de de´veloppement. Une application a` trois karsts pyre´ne´ens permet d'illustrer cette me´thode. Pour citer cet article : D. Labat et al., C. R. Geoscience 334 (2002) 551–556. [Copyright 2002 Elsevier]
