Atlas of Isotope Hydrology - Africa

Naturally occurring isotopes in water provide unique hydrological information, and the associated techniques are highly cost effective. The applications of isotopes in hydrology are part of the IAEA’s programmes related to the peaceful applications of nuclear energy and have the goal of developing appropriate methods for use in water resources management and to assist IAEA Member States in using those methods. This atlas focuses on projects in the IAEA’s African Member States, where environmental isotopes were used to assess water resources in terms of quantity or quality. It presents location maps of study areas, summary statistics and relevant data plots. For each project, a higher resolution map of the study area is provided, together with data tables and plots for median and mean values of d18O and d2H, average annual precipitation, air temperature, and tritium and radiocarbon values.
