Cím:	Examination of sedimentary deposition in the active floodplains of Bereg-plain / Róbert Vass, Gergely Szabó, József Szabó
Dátum:	2010
Megjegyzések:	In the last decade more and more science deals with the problems of the floodplain sedimentation and the higher peaks of the flood water-level, with the same discharge drew the attention to these issues. This process can be explained by the diminution of the cross-section. Since the width of the active floodplain is stabile, the diminution is the consequence of the alluviation (the rise of the bottom level). The chosen sample areas ? three floodplain dilatations (the water slows down here so the sedimentation is more considerable) - are situated in the right bank of the River Tisza between Tarpa and Jánd. We tried to prove the existence of the sedimentation with Digital Elevation Model (DEM) made from 1:10000 maps, comparing the mean altitude of the active floodplains and reclaimed sides. Regarding the supposable that the altitudes of the two areas were the same before the diking of the artificial levees, the recent differences occurred in the period passed from the diking of the levees to the mapping served as a basis of the DEM. The examination based on digital base was completed with the sedimentology analysis of the drilled layers of an alluviating floodplain dead bed. Regarding the altitudes of the active floodplain and the reclaimed side in the three sample areas the same results were yielded using two different methods. The mean altitude of the active floodplains exceeded with 0.2-1.1 m the altitude of the reclaimed sides. Going downstream the rate of the sedimentation is decreasing with the decrease of the gradient.
