Rehabilitation of the Danube inland delta - Szigetköz

The conditions of the surface water bodies in the Szigetköz area of the Danube delta changed dramatically in 1992 following the construction of the Bős-Nagymaros hydropower utilization system.The latter had a significant impact on the groundwater resources and the regional water supply of the soil which led to a drying out of the riverbeds and a lowering of the groundwater table. The biotopes and habitats were significantly damaged as a result, and began to degrade rapidly.  A stakeholder forum was set up to address the problem. The Forum agreed, through consensus, to restore the area to its original conservation status (reference levels of the 1950s) and to implement a series of measures that would help achieve this objective. All activities have since been undertaken to restore the area’s water status and its inherent natural conditions. The rehabilitation works focussed on the river branch systems of the floodplains on the right hand side of the Danube and on the river courses on the dry side of the dikes in Hungary. Comprehensive riverbed arrangements and structural works were built to maintain the target water levels and so renew the riverbank cultures that are associated with them.  Contiguous green and blue corridors have since formed between the water bodies. Their functionality is ensured by the close-to-nature operating regime that is in line with the conservation objectives the corresponding Natura2000 areas.
