Abstract
El área metropolitana de Madrid se asienta sobre una cuenca sedimentaria, parte de la cual da lugar al denominado Acuífero Terciario Detrítico de Madrid (ATDM). Se trata de un acuífero único, muy heterogéneo y anisótropo de gran extensión y espesor, pero de discretos caudales en sus pozos. El modelo conceptual de flujo más admitido sigue las ideas de Hubbert (1940) y Toth (1962) de forma que se explica la presencia de sondeos surgentes sin capas confinantes. Las aguas del ATDM son de calidad aceptable
para la mayoría de los usos y su composición química apoya el modelo conceptual de flujo. Actualmente, el ATDM juega un papel importante en el abastecimiento a Madrid; en breve, el Canal de Isabel II dispondrá de casi un centenar de pozos perforados profundos (hasta 800 m de profundidad) que serán capaces de extraer hasta 100-120 Mm3/año en periodos de sequía.
The Metropolitan Area of Madrid is on a sedimentary basin, partly forming the Tertiary Detritical Aquifer of Madrid (ATDM). It is a single aquifer, very heterogeneous and anisotropic, and large; nevertheless, the yield of wells is poor. The most admitted conceptual flow model is according the thesis of Hubbert (1940) and Toth (1962); so it is possible to explain the existence of flowing wells without confining levels. The water quality of ATDM is good for most uses and his chemical composition reflect the conceptual model of flow. Nowadays, ATDM has an important contribution to water supply of Madrid; in short, the Canal de Isabel II will have almost one hundred deep drilled wells (up to 800 m depth), which will can pump up to 100-120 Mm3/year during dry periods.
