water bodies in porous media
1. Hidrogeological units of porous strata
2. Separation of recharge-discharge areas ? 50
50 water bodies thermal
Coincidence of surface water catchment area and
groundwater bodies at sub river basin level !

water bodies in karstic aquifers
10 cold and 6 thermal karst water bodies 5
groups of water bodies in fractured rocks
Connection to porous strata is considered at the
boundaries!

GIS for designation of water bodies (ARC/Info
ArcView is used in Hungary)
Shallow grw. body
Deep grw. body
together with data bases on hydro-geological data
and human activities GIS gives an easy way to
connect info to water bodies (even if they
change)
Thermal water body

• Map on
• soil types,
• covering layers,
• vulnerability
• are also available

Sub - water bodies
Possibility for grouping !!
Parts of water bodies in critical status
? small sub-water bodies
