  abstract = {{A}t the edge of a semi-arid sedimentary basin, the {P}iedmont plain of the {M}andara mountains is potentially a key area for the recharge of the {L}ake {C}had {Q}uaternary aquifer. {W}e conducted two geophysical surveys based on magnetic resonance sounding ({MRS}) and {T}ime-{D}omain {E}lectromagnetism ({TDEM}) techniques for a better understanding of the aquifer structure at.the piedmont scale in aim to identify preferential groundwater recharge pathways. {MRS} water content and electrical resistivity of the medium confirmed the very heterogeneous and clayey nature of the quaternary aquifer, limiting the recharge to the sandiest areas. {T}hanks to the geophysical methods, these areas have been highlighted near temporary rivers and upstream of the study area near {M}aroua city. {B}ecause of the thickening of the aquifer downstream, the most transmissive zones are in the mid-slope of the piedmont. {T}he geographical distribution of aquifer properties defined by geophysics and the range of {MRS} water content (from <2% to 26%) may be used in the future to constrain groundwater modelling and specify the recharge of the quaternary aquifer at mountain front.},
