MANAGING RESOURCES IN AN EUROPEAN SEMI-ARID ENVIRONMENT: COMBINED USE OF SURFACE AND GROUND WATER FOR DRINKING WATER PRODUCTION IN THE BARCELONA METROPOLITAN AREA

摘要

Barcelona's public water supply depends on surface water, groundwater, riverbank filtration, and artificial recharge. The semi-arid climate provides challenges to supplying water, and methods have been developed to manage the riverbed/aquifer interface at the point of infiltration of the riverbank filtration site. The hydrogeology, water quality, and operational elements of the Barcelona water supply are presented.
