Project summary

Edit project overview to modify the project summary.


The ‘Felsőszentmártoni’ branch, situated in the region of ‘Felsőszentmárton’ settlement, is one of the left-side branches of River Dráva, which has completely cut-off from the main river by now and silted up significantly. The interventions done are the removal of overgrown salicaceae from the riverbed, the removal of silt along the whole length of the branch and it's deposition into the main channel of River Dráva. The reconstruction of the weir that now prevents proper water flow and thus water replenishment of the branch.

Works include:

  • Dredging: removal of 47,735 m3 alluvium
  • Reconstruction of the current weir - height reduction
  • Pipeline laid in the lower parts of the weir
  • Removal of the overgrown salicaceae trees

It supports the work of the Minister regarding the flood management. Its main task is the coordination of flood hazard prevention, river control and flood protection activities, and the management of development projects concerning water bodies. OVF has 12 regional directorates which are coordinating the catchment management planning according to the requirements of the EU WFD. They take preventive and protective measures against floods, carry out status assessments and are the leading organizations in the management and implementation of river restoration projects.
