| الوصف: | Since 2002, a new hydrogeological experimental site (HES) has been developed in Poitiers, France. The overall research objective related to this site is to improve the understanding of flow and solute transport in carbonate aquifers. The benchmarking of various types of numerical models against the HES field data is one of the main research projects supported by three national scientific programs. Within this framework, the purpose of this report is to synthesize existing knowledge about both aquifer geology and flowpath structure, based on core analysis and well logging. The combined use of core-hole data, borehole logs and outcrop data provide valuable information about lithostratigraphy and fracturing. The comparison of flow-meter data with borehole images indicates that flowpaths in the HES aquifer are strongly constrained within (1) subhorizontal karstic structures and (2) subvertical fractures. The presence of karstic levels appears to be conditioned by the stratigraphy and are unevenly developed in the HES. The vertical interconnectivity between the three karstic levels seems to result from fractures occurrence in this limestone formation. Following the observations, data and interpretations, a conceptual model of the Dogger aquifer is proposed. |
