River dynamics



Our research group has dealt with analyses in river dynamics since 1997, mostly with the investigation of the alluvial sections of the Tisza River and its tributaries. In the framework of this study, using the map sections of the second military survey of the Habsburg Empire (sections dated between 1850-1860), the digital database of the ancient river course, between the cities of Tokaj and Szeged, has been developped. For some parts of this section, using the sections of the first military survey of 1783-1786, this older course has been digitized and fit to modern projections as well (see the image below). During this 70-80 years between the two survey, the river course has been obviously changed without any human impact.
Analyzing this river course database, the present-time tectonic activity of the Mid-Hungarian Shear Zone (crossing of the Tisza River between the villages of T iszavárkony and Vezseny, south of the city of Szolnok) has been verified.
To complete and support of the analyses in the river dynamics, the development of the high resolution digital elevation models of the Tisza floodplain has been started as well. Combining these models with the shallow borecore interpretation studies, led by Pál Sümegi (University of Szeged), it is possible to draw the Late Pleistocene-Holocene development history of the floodplain. Moreover, the elevation models act as a physical geographic base of archeological studies, too.
