This database contains mapped data of groundwater data and projects carried out by the Institute. Most data is for Germany, but there is are also global data and data for Jordan and Zambia. Global data include: Aquifer maps (extent), global groundwater vunlerability to floods and droughts, river and groundwater basins, global groundwater resources. Jordan data include: Simplified Hydrogeological map, cross sectional hydrological units, ground contours of key aquifers, sandstone aquifer depth, groundwater level contours, Saturated thickness of different specified aquifers (including A1 A2 A4 A6 A7 B2), Average spring discharge, Groundwater vunlerability. For Zambia data includes: Hydrogeological maps, land use maps (Lusaka), Grounwater vulnerability maps, Hydrogeological maps (4 regional maps)
