Karst conduits modeling using ODSIM - An application case in the Fontaine-de-Vaucluse watershed.

@inproceedings{LeMesnilGM2014,
 abstract = { Fontaine-de-Vaucluse is the largest spring in Europe, with a 1,115 km2 recharge area developed mainly in more than 1000 m thick limestone. Karst development depends on geological environment, namely stratifications, faults and fractures. In this work, we use the Object-Distance Simulation Method (Henrion et al., 2010) to build a 3-D geomodel of caves in the Fontaine-de-Vaucluse karst aquifer (France). In collaboration with local cavers, we collected data on over 350 caves (entrances GPS coordinates, 2D cross-sections and maps, skeletons). About twenty of them have depths greater than 100 m. Whenever available, skeletons have been used to build the conduit paths.
The main obtained information is the 3D view of the karst network and the geometry of the conduits. Thanks to them, we aim to identify stratigraphic and/or structural surfaces, and therefore preferential karstification directions and planes. The generated 3D karst geomodel will then be useful to constrain diagenetic modeling in the view of fluid flow simulations. },
