Abstract

Pumping tests conducted on wells intersecting karst heterogeneities, such as the conduit network, are difficult to interpret. Nevertheless, this case can be solved by assimilating the horizontal karst conduit to a finite-conductivity vertical fracture. In this case, several flow patterns corresponding to the respective contributions of karst subsystems (fractured matrix, small conduits and main karst drainage network) can be identified on the diagnostic plot of drawdown derivative. This is illustrated on two examples from Mediterranean karst systems. A pumping test on a well crossing the main karst drainage network of the Cent-Fonts karst system shows: (1) a preliminary contribution of the karst conduit storage capacity followed by (2) linear flows into the fractured matrix. A pumping test on a well intersecting a small karst conduit of the Bas-Agly karst system shows the existence of (1) bi-linear flows within both the karst conduit an the fractured matrix at early times, followed by (2) radial flows within the fractured matrix and (3) finally the contribution of a major karst cavity. The use of diagnostic plots allows the identification of the various flow regimes during pumping tests, corresponding to the response of the individual karst aquifer subsystems. This is helpful in order to understand the structure of the karst aquifer and flow exchanges between subsystems.
