Simulated change in mean groundwater head between the future (3 degree warming, minimum precipitation change) and past (2015) for the Upper Guadiana Basin, Spain. Simulated by a 1000 m by 1000 m grid. Unit: Meters.

Zones inside groundwater bodies or groundwater bodies potentially leading to operational problems for shallow geothermal use due to a critical chemical composition.

Zoltán Püspöki, Gábor Markos 2024: During the modelling, a total of 593 deep boreholes were stratigraphically evaluated along correlation sections. During the evaluation, the Quaternary sequence, which is usually treated as a single (model) layer in regional geological modelling, was subdivided into 11 layers. The settlement depths of the identified layer boundaries were determined per borehole (593*11=6523 data points), and the resulting layer data table was converted into a format that can be imported ...

Polish Geological Institute - National Research Institute (PGI-NRI) provides measurement results, tests in terms of quality and amount of groundwater, necessary for quantitative and chemical assessment of groundwater. The organisation and scope of groundwater monitoring was adapted to comply with European Community directives, particularly the Water Framework Directive (2000/60/EC), Groundwater Directive (2006/118/EC) and Nitrates Directive (91/676/EEC), in accordance with its specific features resulting f...

Areas dedicated to drinking water or curative water supply, which might limit the use of shallow geothermal energy.

DRASTIC parameter R

Groundwater Recharge Coefficient (Rcoef) for the European domain at 1 km spatial resolution for the period 1981-2010. The Rcoef estimate is based on a machine learning approach trained against gridded Rcoef estimates from seven national pilots in Europe. The Rcoef data set i part of a series of gridded datasets established in the TACTIC project for estimating Potential Groundwater Recharge (GWRpot). The data available are AET, Effective precipitation (Peff=Precipitation-AET), Groundwater Recharge coefficie...

Assessment of the potential threat of groundwater from pollution (i.e. natural vulnerability) is a necessary base for any type of planning and management of groundwater resources. The ultimate goal of the vulnerability map is the subdivision of an area into several units showing the differential degree of vulnerability. Isolated areas or vulnerability classes are presented in different colors or hatches, very easy to understand for the entire professional public, not just geological (which is very importan...

Type of aquifer media distribution map expressed as an index value according to DRASTIC ranges from 1 to 10. The highest values correspond mainly to unconsolidated detrital and karstified aquifers. The lowest values correspond to loam formations and other low permeability geological units.
