Surface water dataset (river discharge), within the upper Oueme watershed (14 000 km2 ), Benin

Long-term measurements (LOP) of river discharge and electrical conductivity of water on the sub-basins of the Upper Oueme. Allow to relate runoff fluctuation to rainfall variability. The electrical conductivity of river water is an integrative measure that allows documentation of the origin of waters (rainfall, surface and sub-surface runoff, watertable drainage). Associated to the chemical characterization of water (CE.Wchem_O), these data give insight into process of runoff generation, allow to compute water balance components and constitute validation datasets for hydrological models.
