Characterizing 3D geomorphology of a karst network using Karstnet : application to the Verneau system ( French Jura )

@inproceedings{vivier:hal-03951805,
 abstract = {This work proposes to analyze the links between geomorphology and hydrogeology of karst networks on the basis of 3D data. The study site is the underground karst network of Verneau (French Jura), which has the particularity of being almost completely penetrable and topographically recognized. The study of the local geological context and the karstogenetic indices allowed us to propose different compartmentalizations: synclines and passage zones, fossil and active conduits, main collector and tributaries. A quantitative analysis of the network geometry in each compartment was then performed using the open-source software Karstnet. It shows that these compartmentalizations result in significantly different geometrical (conduit orientation) and topological (network organization) characteristics. There is thus a morphological compartmentalization within the Verneau network that has evolved over time. A study of water level variations at different points of the network showed that there is a spatial variability of the hydrological response, consistent with the morphological compartmentalization identified in this study. Our results allow us to propose a first conceptual scheme of the Verneau.},
