Groundwater and aquifer data for WISE –perspectives and future needs

• Requirements ( GW status, monitoring, hydrogeological setting, GW bodies )

• Integrate data & information( INSPIRE / SEIS )

• Data needs( interoperable, harmonised )

• Present situation

• Perspectives and priorities

� data and models must reflect the real world

• links with otherenvironmentmedia (water)

Main problems

• poor data on GW

• not harmonised

• not interoperable

• point data vs. polygons

• how respresentative ?

• data quality

• compliance check

= poor European vision

= weak GIS basis

WISE ( Water Information System for Europe )

= overall system for retrieving and visualising

distributed water data

• integrate existing data bases ( EIONET, Waterbase, … )

• map viewer for display in map format

• possibility of combining various data

• tool for data analysis and comparison

= geo-reference ?

= geometries compatible ?

= coherent data concept ?

Why hydrogeologyas a special theme ?

� Processes and undergroundflow often very different fromsurface and above surfaceprocesses

� Geology (rock characteristics& structures) dominant and controlling the undergroundprocesses

Difference between surface water bodies and GW bodies

• Surface water bodies:

= quick response on climatic input, integrated response basedon the catchment conditions

• Groundwater bodies:

= slow response (unsaturated zone, recharge process, aquifer conditions, underground flow conditions, in part merely characteristic for a flow line)

⇒ Hydrodynamic situation essential for GW monitoring

- long travel time from recharge to discharge

- challenge of representative sampling

- need for hydrogeological modelling

Data and information for WISE

• General

- GISCO- NUTS- CORINE- Continental DEM- CCM- other satellite data

(GMES, GEOSS, Google)

• Surface water

- EIONET, Waterbase- CCM- RDB and other WFD data

• Underground data

- EIONET / GWB / point data- soils (ESBN)- geology, structure- hydrogeology- geochemistry- hydrochemistry- geophysical data

• Quaternary geology (scanned maps)

• digital geological data (IGME 5000, vector data)

• geophysical data (Geothermal Atlas of the EU)

Groundwater Bodiesin Waterbase

• Commom standards needed

• Harmonised and interoperable data

• Homogeneous datafor Europe

Methodology, content and colour system of the IHME

• colour wash (for type and hydrogeological significance o f rock bodies)

Blue: intergranular aquifers

Green: fissured and karst aquifers

Brown: non-aquifers or only local potential

• background ornament for lithological rock type

various types in grey

• line and point symbols for special features

full blue for surface water, springs and karst

violet for groundwater features, e.g. groundwater contours

orange for chemical and thermal features, e.g. thermal and mineral springs

red for man-made changes of the natural GW regime

black for geological features, e.g. lithological boundaries, faults

Groundwater relevant information

• Exchange between surface water and groundwater(groundwater discharge in springs, wetlands, rivers; pumping form wells for domestic, agriculture, industry; recharge depending on precipitation, topography, soils, land use)

• Hydrodynamics(3D appraisal of groundwater cycle, depth to GW, density of river network, flow velocity, fluxes)

• Hydrogeology(lithology, aquifer type, structure, permeability,thickness)

• Hydrochemistry(rock-groundwater interactions, geogene GW chemistry, hydrochemical stratification, pressures and anthropogenic pollution)

Towards reliable, harmonised aquifer and groundwater data for WISE

Urgent needs

• digitise and geo-reference IHME data

• develop a general legend and a hydrogeological typologyof Europe

• analyse and interprete existing GW related data

• check groundwater bodies, compliance check

• update European data by using WFD data

• new, updated coherent data set(participation of Geological Surveys and EuroGeoSurveys)

• integration in WISE

• web mapping application compatible with GoogleEarth

Towards reliable and harmonised aquifer and groundwater data for WISE ( II )

Medium and long term perspective

• generate new, additional data

• depth to groundwater

• hydrochemical background values

• vulnerability of aquifers to pollution

• hydrodynamic zonation and mapping

• coupling hydrodynamic mapping with modelling

• analysis and optimisation of monitoring network forgroundwater
