The Recession Curves of Lys Springs (France)

Curve Recession, Infiltration Zone, Sunken Karst


In this work, we applied the study method of recession curves to the Lys springs discharge in order to characterize the sub-zone infiltration and the sub-zone sunken karst aquifers, to simulate the diminutions curves shape and to classify the Lys springs. Two types of recession curves were studied: main and lower-water recessions during many hydrological cycles. The achieved results shown clearly that the behavior of the Lys springs is different, on one hand from a hydrological cycle to the other one and according to the reserves state of the system.
