The socioeconomic welfare of northern Korinthos region is largely based upon groundwater resources adequacy. Regulatory authorities have been alarmed as increasing water demand over the last two decades has resulted in considerable head decline and quality deterioration. The current study attempts to develop an integrated and versatile system to handle time-expanding water resources related data. It can be used as a powerful tool by decision makers to perform a global "at a glance" updated appraisal of resource conditions via theme databases and maps. Sustainable water resources management policy planning is assisted and necessitated; raising of low environmental public awareness is facilitated.
