International audience; In West Africa, infiltration and groundwater recharge processes in hard rock areas are depending on climatic, surface and subsurface conditions, and are poorly documented. Part of the reason is that identification, location an

During the last quarter of the 20th century, West Africa underwent a particularly intense and generalized drought. During this period, the biggest drops in streamflow were observed in the Sudanian zone rather than in the Sahelian zone, but the reason

International audience; In basement catchments of subhumid West Africa, base flow is the main component of annual streamflow. However, the important heterogeneity of lithology hinders the understanding of base flow generation processes. Since these p

Discrimination of Rocks with Different Hydrodynamic Properties Using MRS, EM and Resistivity Methods

Autor: A. Legchenko, M. Descloitres, L. Séguis, M. Wubda

Publikováno v: Scopus-Elsevier

A geophysical survey has been carried out on a watershed (10km²) in north Benin for contributing to a parameterization of hydrological modelling. For delineating rock and soils units we used Electromagnetic (EM) conductivity mapping. For estimating
