Combined Use of Electrical and Flow Parameters for Hydrogeological Characterization of Piedmont Aquifers in the Basement Complex

Abstract:
This study is an attempt to clarify and understand the structure of the basement, aquifer behavior and to determine the parameters that influence the productivity of drillings in the piedmont region in the Far North of Cameroun, with the optics to guide future hydraulic campaigns in similar regions of the World. The data used are the vertical electrical soundings collected during geophysical surveys and parameters identified during the drilling works. The analysis and the interpretation of qualitative and quantitative data have highlighted terrain models and two types of aquifer, one on the surface alluvium and another in the deep aquifer of the fissured/factured basement horizons. The statistical analysis of the boreholes productivity has permitted to conclude that: the depth of drilling is not the guarantee of a high flow rate; in the alluvium or alterite formation, they flow rate increases with the thicknesses between 1 to 35 m and decrease for higher thicknesses; while in fissured aquifer significant water arrivals are only observed in the first 15 m of the fissured/fractured rock; The extreme variability of flows observed around neighboring boreholes, emphasizes the discontinuous nature of these aquifers.
