Full textThe crystalline basement aquifers present a major challenge for today's hydrogeologists due to their heterogeneity and discontinuity. They are the main source of drinking water in several regions of the world, particularly in sub-Saharan Africa and Chad. However, the crystalline basement aquifers in Chad have been poorly studied, making it difficult to exploit them to meet the water needs of the population. Our study focuses on the Guéra region, located in the Lake Chad Basin, which is characterized by a crystalline basement composed of 90% granitoids and metamorphic rocks, and subjected to a Sahelian-Sudanian climate. This region was chosen for this study due to the availability of existing data. Despite efforts to improve access to the resource using hydrogeological and geophysical techniques based on 1D and 2D electrical methods combined with lineaments, the failure rate of water wells remains high.In order to better understand the functioning of the crystalline basement aquifers and improve access to drinking water in this region, we propose in this thesis a multidimensional approach, combining geology, hydrogeology, geophysics, geochemistry, and machine learning. The hydrogeophysical approach, based on the in-depth exploitation of numerous existing data (technical data from 798 wells, 700 EM34 profiles, and 592 electrical panels), has allowed us to identify the main formations on which the local hydrogeological conceptual model is based, as well as their range of electrical resistivity, and to determine the factors that control the productivity of the aquifers. The installation of a preliminary automated piezometric monitoring network since 2021 has addressed the dynamics of groundwater fluctuations. Geochemical and isotopic methods, applied to 211 samples, have allowed us to identify and understand the processes of groundwater mineralization, differentiate between different aquifer formations, validate the conceptual model, assess vulnerability, and understand recharge mechanisms and groundwater age. Finally, a machine learning method has been tested using the data produced in this thesis to evaluate the potential of this approach to identify productivity criteria and map on a large scale the areas where the potential for groundwater is favorable for well installation.Keywords: Crystalline basement aquifer, geophysics, hydrogeology, conceptual model, geochemistry, machine learning, Guéra (Chad)
