In the Lorraine region, Oxfordian limestones have a thickness up to 250 meters, but despite of that, they appear poorly karstified, except in the the Meuse/Marne interfluvial area. On this plateau, named "Haut-Pays", karst is known since the Roman epoch at Grand, and from the 19th century onward also at Trampot. Since the 1960s, the karst of this sector was subject of many scientific investigations, especially speleological, which led to an inventory of exo- and endokarstic forms where possible (Hades network). Colorimetric tracer tests made it possible to establish models of underground water circulation in the limestones. Finally, the oxfordian karst of this sector already was the subject of many works. However, results were obtained only from specific measurements, either in time or in space. The investigation of this karstic system, starting with recent hydrometric data (2007-2008), being conducted over at least a hydrological year, brings a new light on this karst. On an annual scale, the hydrological balances make it possible to calculate the surfaces of the catchment areas to the discharge systems. The functional analysis, starting with the medium daily of hourly discharge, makes it possible to specify the nature of the oxfordian karst on the plateau, where this geological formation outcrops. It feeds the regional artesian aquifer flowing towards the center of the Paris basin.
Utilisation des caractéristiques pétrographiques des galets issus des diverses nappes alluviales pour établir des corrélations avec la vallée de la Haute Moselle à l_amont Taous, 1994. Etude de 4 sites correspondant aux 2 terrasses moyennes et aux 2 basses terrasses à Dommartin-lès-Toul, Pierre-la-Treiche, Chaudeney et Liverdun. Enfin, les AA. ont établi l_impact de la capture de la Haute Moselle sur le modelé fluviatile de la région de Toul, ce qui a fourni une dernière estimation de la chronologie des événements.
