| contents | Characterization of groundwater vulnerability to fulfill requirements of the water framework directive of the European Union Hans-Jürgen Voigt Thomas Heinkele Christoph Jahnke Rüdiger Wolter Ciencias de la Tierra European Union Groundwater vulnerability Aquifer vulnerability assessment is an important basis in order to fulfill demands of the water framework directive of theEuropean Union. For the determination of the groundwater vulnerability different methods can be used. In this paper, the intrinsicvulnerability of groundwater resources is defined as the worst case of a pollution input in the unsaturated zone without interactionor decay of the contamination substance on its way to groundwater table. It can be assessed by the transit time of the percolatingwater from surface to the groundwater table. To asses the groundwater vulnerability according to this definition, a method basedon a simple analytic model which determines the retention time of the percolating water in the unsaturated zone is presented. Thecomputation of the retention time is based on lithological characteristics of the vadose zone and on the groundwater recharge rate.The method has the advantage that the necessary input data can to be derived from available maps and can be handled by a GIS. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843405 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.43 |
