HYDROGEOLOGICAL BACKGROUND OF PAMPA DE HUARA. PROV. OF TARAPACA. CHILE

Abstract

This paper presents a map of Northern Chile, scale 1: 1.000.000 showing the geological units which determine the existence of underground water in the Pampa del Tamarugal (Province of Tarapacá). The author analyses, at the same time difíerent íactors playing a role in the runoff, storage, and discharge of  waters in the whole Province oí Tarapacá. In addition, a map (scale 1: 100.000) of a sector of the Pampa del Tamarugal, known as Pampa de Huara, is analysed, because in this particular area ancient agricultural íields have been discovered. Such íields can be reused by means oí the intensive application oí underground water, present in the area.
