We are interested in evaluating the effect of a pumping in an aquifer influenced by former mines from a quantitative aspect. For this purpose, we have developed a simulation tool allowing the piezometric level to be evaluated in a realistic way, having at disposal the following data: the geometry of the reservoir, information concerning the surface (landcover), the precipitations and the daily volume of pumped water. We will explain the method used to set up the model and present first results obtained in former coal mine of Rochebelle - St- Martin de Valgalgues located Cévennes, South of France.
