This paper explores a new tool which uses remote sensing and isotope hydrology in investigating flooding. It examines flooding in the lower valley of the Senegal River, using essentially remote-sensing signal distribution and isotopic data, which characterize different water masses in the area of study. The spatialization of information drawn from the isotopic data makes it possible to define replenishment patterns of the alluvial aquifer, flow regime and hydrodynamism of the system. The cartographic documents generated using these complementary approaches can be used as tools for decision-making concerning land occupation in the region in order to manage flooding in the estuary and the lower valley of the Senegal River.
