| dc.description | The river regulations of the 19th century have affected each of our rivers to a different degree. In thecase of the River Bodrog it was stronger than the average. In our paper a section of the river betweenBodroghalász and Szegi was examined, the extent and intensity of river channel changes wasintended to be determined. The applied series of maps and aerial photos was georeferred and the riverchannel was vectorized. The morphometric parameters of the channel were measured and the changeswere evaluated using the created database. From methodological aspect we concluded that the 9variables can be grouped into 3 factors therefore most of the indexes can be substituted. We measuredthe changes of length and lateral shift of the channel using GIS methods. Three development periodswere identified based on our results. In the first period the development of the river was characterizedby natural processes. Then, the development of the river altered owing to the antropogenic impacts. Inthis transient phase the average shifting of the channel was 7.43 m/y. In the third term this valuereduces to 0.2 m/y as the river is getting to reach the equilibrium stage. | |
