Prospection géophysique pour la recherche de l'eau souterraine en Haiti

Abstract

The National Service of Water Resources (SNRE) of Haiti has, within the United Nations project PNUD/DTCD/HAI/86/003, Développement et Gestion des Ressources en Eau, made an inventory of geophysical data in Haiti and executed additional studies in seven alluvial plains. The applied geophysical methods in groundwater exploration are electrical sounding and electrical, electromagnetic and magnetic profiling. The methodology used and the final results for three regions are presented in this paper, viz. the Colombier Plain, the Arcahaie Plain and the Cayes Plain. Interpretation of the data obtained revealed the true resistivity of the alluvial aquifers and the depth of the basements. In combination with the piezometric level of the groundwater, the exploitable aquifer systems were determined. True resistivities of the basement enabled a determination of the extent of a zone of productive limestones in the Colombier Plain. © 1992 Taylor & Francis Group, LLC.
