Abstract:
The aim of the joint project is to create a comprehensive distribution overview (isoscape) of stable water isotopes and tritum concentrations in groundwater for Germany for the first time. This is done from existing data from individual state offices, from the literature, from companies
as well as new measurement campaigns as part of the project application. Contacts with the respective countries were established via the UBA, LAWA and BLA-GEO. This data and the maps generated from it are available to potential users in an interactive, long-term and expandable way
provided. All data and their visualization will be made available via an internet application at the Federal Institute for Geosciences and Natural Resources, which all users can access free of charge. The system should be expandable using historical data and future measurements after the end of the term. The merger of the previous, fragmented ones
Data sets and their targeted expansion will create a completely new basis for supra-regional groundwater assessment in Germany. Signals of climate change, which are already visible today in the isotope ratios of precipitation, lysimeter leachate and surface water, are now being combined with isotope data for water for the first time
Compartments comprehensively recorded and systematically evaluated. Together, tritium and stable water isotopes represent an innovative tool on the basis of which sustainable groundwater extraction can be regionally targeted in the face of a changing climate and changing land use.
