Techniques gophysiques de type lectromagntiques appliques l'tude du karst nivernais, 1985, Couturaud A. , Benderitter Y.
STUDY OF KARSTIC DRAINS ENVIRONMENT BY GEOPHYSICAL TECHNIQUES (ELECTRIC AND ELECTROMAGNETIC) - Geophysical techniques (electric and electromagnetic) are tested on two underground rivers of the Nivernais karst (Bourgogne, France). The first site is an important dry valley and the second locates at the border of a plateau. No sharp image of the known galleries were obtained on both sites, but the first one shows a higher density of anomalies corresponding to the cave. In the axis of the valley is a weak resistivity anomaly, without any relation with the karstic drainage and which has not superficial origin. This anomaly would be the consequence of a fracturing of bottom valley. Others zones of fractures are evidenced, cross-cutting the conduits. The second one has also weak resistivity zones, independent of the cave, which are interpreted as annex system (hydrological sense). Some reflections on theoretical and methodological aspect of this type of research are proposed.

Des cavits dans la couverture limoneuse des plateaux nivernais (Nivre), 1986, Chabert, C.
CAVES IN THE SOFT COVER OF THE PLATEAUX DU NIVERNAIS (NIEVRE, FRANCE) - North of the Massif Central, around Nevers, the jurassic limestones are covered with a mio-pliocene silt mantle characterised by different caves: collapse dolines in relation with the crypto-karst situated into the underlying limestones and little holes developing in the silt mass (ex.: ponor of Bois de la Grange, length: 11 m). The tertiary mantle and the forests take a prominent part in the regulation and the physico-chemistry of karst waters.

Le karst nivernais : aperu gomorphologique et hydrogologique, 1989, Couturaud A. , Orange A.
The Nivre karst: geomorphologic and hydrogeologic considerations - Western part of Burgundy and southern part of the Paris basin, the Nivernais karst takes from both regions their lithologic and structural features: Middle and Upper Jurassic carbonate formations, monocline structure with horsts and grabens. But its particularity is in the thick superficial formations, that are supporting a wide mantle of forest, and that determine its morphology, its hydrodynamic and its hydrochemistry. The karst area is distinguished by closed depressions and by the abundance of valleys. The penetrable cavities are scarce and of a little extension, and are principally underground streams. The study of the hydrodynamic and the chemistry of some springs have shown the complexity and the variability of the dynamic of the karstic systems that depends essentially on the superficial formations.
