Abstract

The three towns of Khartoum, Omdurman and Khartoum are located north of the capital of Sudan. This capital has agglomerated to reach more than 7 million inhabitants. The present situation is confronted with a dramatic shortage in freshwater supply. The treatment of surface water from the Nile became costly, particularly in flood season. Thus the authorities turned towards developing groundwater resources. The electric tomography, obtained by the combination of Vertical Electrical Sounding (VES) and well logs, turned out to be very efficient to provide a complete electrical image of the underground from the surface until about 200-m depth. This methodology constitutes a very cheap guide for the evaluation of the quality of groundwater resources in the Khartoum area. To cite this article: M.T. Hussein, H.S. Awad, C. R.

Résumé

Les trois villes de Khartoum, Omdurman et Khartoum nord forment conjointement la capitale du Soudan. Cette capitale comprend plus de 7 millions dʼhabitants, et est confrontée à un manque dramatique dʼalimentation en eau potable. Le traitement des eaux de surface du Nil est devenu coûteux, particulièrement à la saison des crues. Cʼest pourquoi les autorités se sont tournées vers lʼutilisation des eaux souterraines. La tomographie électrique, résultat de la combinaison des sondages électriques verticaux et des coupes de forages, sʼest révélée très efficace pour fournir une image électrique complète du sous-sol jusquʼà une profondeur dʼenviron 200 m. Cette méthode a fourni un guide utile et peu onéreux pour lʼévaluation de la qualité des ressources en eau souterraines de la région de Khartoum. Pour citer cet article : M.T. Hussein, H.S. Awad, C. R. Geoscience 338 (2006).
