- 4.3. Identification of data gaps and uncertainties in the Tisza River Basin

The characterisation of important transboundary and national groundwater bodies (GWB) carried out for the purposes of this report was a valuable exercise, which can serve as the basis for future bilateral exchange and harmonisation of GWB information in the Tisza Basin. The evaluation of the GWB data submitted by the Tisza countries has indicated several remaining gaps and uncertainties. In order to verify this, more data and
future bilateral exchange are required in the future. (5.3. Identification of data gaps and uncertainties - p.91)
