Karst genesis modelling of a regional Mediterranean aquifer (Lez, France).
Résumé
The Lez aquifer (Montpellier, France) developed in a
Mediterranean setting, through several stages.
Problem : The Messinian crisis is considered as mainly having
driven the architecture of the karst conduits.
Questions : Is this stage the most important in terms of
impact on Lez aquifer architecture, and how does it compare
with the previous stages?
Tools : To answer to these questions, a numerical model
(GODIAG, TOTAL S.A.) has been constructed for the Lez
aquifer. It allows to test several scenarii of the evolution of the
karstic network through time.
