Apports des mthodes hydrologiques dans la comprhension des coulements en pays calcaire : exemple des bas plateaux jurassiques du haut bassin de la Marne (France), 2004, Lejeune Olivier, Devos Alain
Hydrological methods for the study of river flows in limestone areas: the Marne basin in the Jurassic low plateaux (NE France) - We investigated the geographical heterogeneity of river flows in limestone areas in the upper Marne valley (interfluves of Marne-Aube and Marne-Meuse) by using the low water profiles, the modelling of discharges and the study of physicochemical parameters. We studied five basin-slopes belonging to the Marne-basin (4500 km2) and the measures were realised between 2001 and 2003 at the time of low water periods. We used an instrument (perche intgration type Pire) in order to measure the stream flows of river water. We also measured temperature and electrical conductivity in order to identify the origin of the water. The measures allowed us to identify low water profiles of the river and we also can map the discharge in low water periods. The methods show the water flow inside a basin-slope and also hydrogeological connections to the adjacent basin-slopes. Thus, they revealed that the divergence or the concentration of discharges depends on the limits of the aquifers sections related to their morphological structure and on the differential incision of the valleys. We obtained a hydrogeological pattern of interfluves and we can distinguish between areas of water lost and areas with an increasing of water volume. We confirmed this process of water transfers, called the active stream piracy, which is often approved by hydrogeologic tracers. This active stream piracy revealed by these methods in warm or interglacial period, prepare future stream piracy of surface, collectively recognised in the beginning of cold phase.
