Transboundary groundwaters shared by Austria and Hungary in the Raab/Raba Basin.42 The aquifers or groundwater bodies are commonly only a few metres thick, up to about 10 m. The thickness of Günstal aquifer and groundwater bodies of the Günser Gebirge Umland group reaches some 30 m, and Rabnitzeinzugsgebiet 165 m. Groundwater is mainly used for drinking water and for the agricultural sector (including irrigation). For all the groundwaters, exept Günstal for which it has not been specified, the dominant groundwater flow direction is from Austria to Hungary. Name and number Raabtal (No. 63)
