Atlas of Isotope Hydrology – Africa

This Atlas of Isotope Hydrology focuses on Africa. Data from nearly 10 500 isotope records gathered from about 80 IAEA projects in 26 African countries from 1973 to 2007 are included. For each country, a digital elevation map is provided that shows major water bodies, locations of stations in the IAEA global network of isotopes in precipitation (GNIP) and the project study areas. Summary pages for each project include a higher resolution map of the study area, and data tables and plots for median and mean d18O and d2H, average annual precipitation and air temperature, tritium values, and radiocarbon in groundwater.

The Isotope Hydrology Information System (ISOHIS), maintained by the Isotope Hydrology Section of the IAEA, has been the source of the hydrological and isotope information used in the compilation of this Atlas of Isotope Hydrology – Africa. The isotope information presented in the Atlas can be downloaded through the online application WISER from the internet site: http://www.iaea.org/water.

The isotopic information presented in this unique Atlas is expected to be a valuable reference to scientists, practitioners and policy makers engaged in the field of hydrology.
