- About 45 members: The main multidisciplinary research activities at LRAE
have been focused on supporting sustainable and Integrated Resources
Management (IWRM) through surface and groundwater characterization in
Tunisia and evaluation of aquifer’s vulnerability to natural and human
induced contaminants.
- Since 1998 � more than 100 publications in peer reviewed journals, on Isotope Hydrology,
� about 25 PhD thesis and 40 Master defunded in the isotope hydrology and geochemistry. Many other PhD and Master are in
progress.
Laboratory of Radio-Analyses and Environement
The laboratory was created in 1999 at the National School of Engineers of Sfaxwithin the framework of the reorganization of research activities carried out bythe Ministry of Research and Higher Education of Tunisia (During 1994 to 1999, itwas the Research Unit "Isotope Geochemistry and Paleoclimatology).
The staff includes multidisciplinary teachers, students, researchers andtechnicians from different institutions of Higher Education and Research.
Regional Designated Centre (RDC)
The LRAE have been selected as Regional Designated
Centre (RDC, under AFRA activities) to play a leading role in AFRA and TC-
IAEA projects as well as in the application of isotope techniques in water
resource studies and management.
As RDC the LRAE is providing under AFRA and TC-IAEA projects:
� Analytical support for Afra member state;� Training in the field of isotope hydrology;� Organize meeting and TRC and contributes as Lecture on Isotope
Hydrology.
The LRAE (represented by his director) is designed as the PSC for the RAF8048 and RAF7013 projects.
The LRAE took also part for several inter laboratory
comparison exercise for laboratories engaged in routine analysis of 2H, 18O and 3H isotope composition of water samples, controlled by IAEA-Isotope
Hydrology Laboratory.
