Sažetak
River Danube, as a main European river, is continuously changing its’ riverbed and embankments due to hydrological and morphological processes as well as human activities. Previous activities on river regulation and current situation imply that river section from kilometer 1380 up to kilometer 1433, from mouth of Drava River at Aljmaš up to Hungarian border, needs urgent measurement to prevent further bank erosion which is most intensive in Kopački rit area. Beside this, deposition of sediments in the river inside the shipping corridor needs long and intensive mitigation measures. In past period, there were no significant activities undertaken on protection of river banks in area of Nature Park Kopački rit, which resulted in greater erosion and negative impact on Nature Park. Right bank erosion process followed by subsidence of this area caused reduced embankment width to just few meters. Average erosion rates are as high as 60 meters in 30 years. This amount was calculated in region between river kilometer 1401 and 1407 where actual values range from 10 to 100 meters. Considering the height of the riht river bank and morphology of the adjacent terrain the section between river kilometer 1400 and 1410 is the most endangerd. Fact that the Nature Park Kopački Rit is threatened by the embankment and riverbed erosion that would cause a great impact on the morphology and the wild life in Kopački Rit have initiated the Croatian Water Authority to start with urgent embankment protection activities at the most endangered locations. In order to prepare project documentation, ydrological activities and field investigations were undertaken to ensure relevant input data and valuable basis for mathematical modeling of stream flow. This project has the main goal to protect the most eroded part of the Danube River in Croatia (river kilometer 1400 to 1410) as a continuation from previous activities in order to provide basis for river regulation and shipping corridor. Beside this, project will be very seful basis for bilateral and trilateral cooperation due to fact that field measurements and cartography activities have been recently carried out (recent maps, river cross sections based on GPS, velocity and discharge easurements based on Doppler equipment etc.). Result of this project is proposal for river regulation and shipping corridor together with activity plan for Croatian side of the river.
