Groundwater flow paths in a glacially affected flat area in the Netherlands
Well field Garyp is abstracting deep groundwater from fluvioglacial sediments, which are covered by glacio-lacustrine clay. This drinking water abstraction is hampered by rapid salinization of the abstraction wells. A detailed ground-water modelling study was done, to reveal the water pathways and the groundwater-surface water interaction. It was concluded that shutting down wells, nor reducing abstraction rates or reduction of well screen depth would result in significantly less abstracted water from brackish layers. Key words: Groundwater hydrology, groundwater-surface water interaction, MODFLOW modeling, salinity.
