• Resumen

  • A methodology for construction of groundwater vulnerability, using a Geographical Information System (CIS), has been developed as a tool for protecting the groundwater resources. The maps were constructed by using four subsidiary layers, each of which reflects a particular parameter that governs acidification. The factors that determine vulnerability are: elevation above sea level, morphology of the terrain, areal extent and type of vegetation cover, and geology. This methodology has been applied to Grio river basin. The vulnerability map obtained has been contrasted with chemical data from springs and streams of studied area
