That water-table cave is in theory the water table offers the prime environment for cave development as it provides the shortest route through the phreas and is potentially more active chemically due to the presence of the air/water interface. however, geological factors determine the details of cave inception and enlargement, and passages most commonly form just below the water table as a shallow phreatic variety of cave development. development of this type is believed to be responsible for the 'levels' of cave passage found in some areas, as in the flint mammoth cave system, kentucky. true water-table caves are rare except on a limited scale as extensions to cliff foot notches margined to tropical swamps. also under these conditions, the water table may adjust down to the level of a mature phreatic cave and then modify the passage with horizontal dissolution notches - as is common in the caves of mulu and niah, sarawak [9].?

Apports des méthodes hydrologiques dans la compréhension des écoulements en pays calcaire : exemple des bas plateaux jurassiques du haut bassin de la Marne (France)
Abstract:
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 à intégration type Pirée”) 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.
