Detection of Water Leaks in Foum EI-Gherza Dam (Algeria)

摘要

The main objective of this work was detect water leakage combining classical and nuclear techniques (isotopic and radiotracer).Classical methods concerned the follow up of physico-chemical parameters (conductivity,temperature and chemical composition).Isotopic and radiotracer techniques concerned the isotopic composition (oxygen18 and tritium) and labelling of the reservoir (Fluorescent tracers),respectively.The investigation was performed by a research team from the ' Algiers Nuclear Research Centre'in collaboration with engineers from the ' National Agency for Dams'.The chemical and isotopic results have shown no influence of dam water on the surrounding aquifers.Dye tracing has shown a faster water circulation through complex pathways for the right bank as compared to the left one.
