Zusammenfassung:Groundwater vulnerability mapping is increasingly being used to design aquifer protection and management strategies. This paper presents a dynamic visualization method to groundwater vulnerability mapping. This method—called V-DRASTIC—extends the capacities of DRASTIC, an overlay/index technique that has been applied worldwide to evaluate the condition of hydrogeological factors and determine groundwater vulnerability at regional scales. V-DRASTIC is based upon psychophysics’ principles (a theory that describes the people’s response to a stimulus) to generate alternative groundwater vulnerability categorization schemes. These are used as inputs in a fuzzy pattern recognition procedure to enable planners, decision makers and stakeholders identify which scheme conveys meaningful information regarding groundwater vulnerability across a territory. V-DRASTIC was applied in the groundwater vulnerability assessment of two urban watersheds in Mexico.
