Research conducted by the University of Szeged has attracted international attention and could provide a new basis for water replenishment planning

The effects of climate change no longer pose a threat to the future, but to the present. In the Southern Great Plain, the frequency of droughts and the severity of water shortages have reached critical levels. To address this problem, the Department of Physical and Environmental Geography at the University of Szeged carried out a unique series of studies on behalf of the National Water Authority (OVF) and in collaboration with the Lower Tisza Region Water Authority.

Geospatial analysis aids decision-making for professionals

Geographers from the university identified thousands of local depressions and former riverbeds, then used complex GIS analysis to pinpoint the areas where retaining water locally or replenishing groundwater reserves is technically feasible. György Sipos, head of department and leader of the research in South Békés, emphasised that increasing the region’s resilience to climate change cannot be achieved on the basis of subjective decisions.

Experts have developed a scientifically sound decision-support system based on a combination of topographical, pedological, land-use and infrastructure data. The significance of the project extends far beyond the region’s borders.

The methodology can be applied throughout the country

The methodology developed by the University of Szeged could serve as a national model for the water authorities’ work on the rehabilitation of water-deficient areas in the Great Plain. The international excellence of the research is demonstrated by the fact that

A paper presenting an earlier version of the methodology has already been submitted to one of the world’s most prestigious journals in the field of water science.

Help with planning

József Gacsályi, Deputy Technical Director of the OVF, stated that the results of the research are not merely of theoretical significance, but provide direct assistance in planning technical interventions in water management. The aim is to develop a complex, climate-adaptive water management system that will halt the drying out of the landscape and, in the long term, contribute to improving water security in South Békés and, subsequently, across as much of the Great Plain as possible.
