Analyses of One of the Rare Natural Retention in the Middle Danube

In the middle course of the Danube river there is one of the rare, but still large natural areas, where the large waters of this river can pour out into the wider inundation area. As a consequence, along about fifty kilometers of the courseupstream around cca 1370 rkm of the Danube, transformation of large water waves hydrogram is occured. In the paper the measurements from observation of the Danube and Drava water regime are analyzed in the zone of their connecting. The available data are used to make the hydrogram approximation of some water waves and the retention effect of the existing natural conditions is examined. The example of the possible quantification of retention characteristics is given. Although for the analyses the uncoordinated time data were used, the results can be still considered as respectable. For the quality observation it is necessary to extend the existing monitoring and to work on the uniting of the measurements and data base collected in this area.
