Short summary
Flows out of Lake Chad are constrained by a modeling of the hydrological, chemical, and isotopic budgets, based on a review of existing data along with new data. This innovative approach allows one to determine the proportions of evaporation, transpiration, and infiltration out of the lake while the two last flows are often neglected in semi-arid environments. Moreover, it allows to investigate the lake hydrological and chemical regulations under the large climatic changes in Sahel since 1950.
