  abstract = {{H}ydrological processes and water balance of a tropical crystalline bedrock catchment in {B}enin ({D}onga, upper {O}ueme {R}iver). {H}ydrodynamic, geochemical, and subsurface geophysical investigations, for two consecutive years with contrasting rainfall 2 conditions, were used to characterize the hydrological processes occurring, and the water balance of a 586-km(2) watershed in {B}enin ({A}frica). {T}he water table's monitoring shows that recharge occurs by direct infiltration of rainfall, and represents between 5 to 24% of the annual rainfall. {B}oth surface water outflow, limited to the rainy season, and water chemistry indicate a weak groundwater contribution to river discharge. {T}his implies that the calculated variations in annual runoff coefficients (of 14 and 28%) are mainly governed by surface and subsurface flows. {T}o cite this article: {B}. {K}amagati et al., {C}. {R}. {G}eoscience 339 (2007).},
