BAKKALI, Saad. Utilización de sondeos eléctricos para el diagnóstico del potencial hídrico de la región de Tizeght (anti-atlas marroquí). Ing. invest. y tecnol. [online]. 2006, vol.7, n.2, pp.71-84. ISSN 2594-0732.

The improvement of the access to water in the isolated and wedged zones, is a priority which only justifies the intervention of associations of local and regional development in the socio-environmental fields. Within this precise framework, at the request of Anssis Association for the development of the area of Tizeght, a geophysical study by electric methods - electric Surveys Schlumberger- was carried out in the province of Tafraoute , more precisely on the site of the village of Anergui in the area of Tizeght. The geophysical study consisted of an electric prospection by D.C. current. 5 vertical electric surveys were carried out. The measuring apparatus of the resistivity is GTR-2 with summation of signals and automatic offsetting of the spontaneous polarization of Geotrade Instruments. The data processing was carried out using the software WinSev 3.3 of Geosoft. It is envisaged by this study to contribute to the improvement of the knowledge of the hydrous potential of the zone of study. It is also planned to study the localization of the sources and the located makes of water. The diagrams of the longitudinal and transverse evolution of the aquifer are proposed.
