That Dupuit's assumption is a simplifying assumption for the solution of a free surface well flow problem [16] (e.g. a water-table aquifer.) it is based on the assumption that the slope of the phreatic surface is negligibly small so that the equipotential lines are vertical and flow is essentially horizontal.?

La grotte de Saint-Marcel (Ardche) : un rfrentiel pour lvolution des endokarsts mditerranens depuis 6 Ma, 2006, Mocochain Ludovic, Bigot Jeanyves, Clauzon Georges, Faverjon Marc Et Brunet Philippe
Saint Marcel Cave: an important site for the evolution of the mediterranean endokarst in the last 6 million years - The plateau of Saint-Remze is a mesozoic carbonate platform located close to the Rhne valley. This carbonate platform is intensely karstified, as proven by Saint-Marcel Cave, which is 53 km long. It displays several horizontal levels. The upper and middle levels are dry most of the time. They are composed of large horizontal conduits extending over several kilometers. The lowermost third level is active and partly drowned. Scuba divers have reached a depth of 65 m below the Ardche. The horizontal levels are not controlled by geological structure. Consequently, the distribution of the horizontal levels depends only on the base level which constrains the whole organisation of the Ardche karst. Around the Ardche Canyon and the Rhne Valley, the identification of the marks made by the messinian salinity crisis allows to reconstruct the evolution of the local base level. This reconstruction allowed us to study the Saint-Marcel Cave in a geodynamical and chronological frame over the last six million years. The morphological investigations in the cave, combined with the study of the base level change, have shown three main stages of speleogenesis and two main types of water flow. Following entrenchment of the deep messinian canyons during the salinity crisis, cave levels developed according to the very deep base level of that time. At the end of the crisis, at 5.35 Ma, the Pliocene transgression caused a sudden rise of the base level. The messinian valleys as well as the karst outflows were flooded. This hydraulic change produced a per ascensum genesis of some shafts that are called chimney-shafts. This per ascensum genesis of chimney-shafts repeated itself at each stage of the Pliocene base level rise. During the Pliocene (5.32 to 2 Ma), the infilling of the messinian canyons by fluvial sediments shows that the Ardche river had several long stages of base level stability, allowing the development of new cave levels. The karst system was fed by both local recharge from the Saint-Remze Plateau and large underground shortcuts through the Ardche river meanders. The detailed study of the main levels in Saint-Marcel Cave reveals the existence of intermediate stages in the evolution of the base level, allowing us to refine its knowledge.
