The Centre's primary aim is to play a fundamental role in promoting the common weal and in building the foundation for the future through valuable scientific achievements based on highly promising discovery research. The Centre consists of three institutes, the Balaton Limnological Institute, the Danube Research Institute and the Institute of Ecology and Botany. General Driectorate of Water Management - General Directorate of Water Management (OVF) is a background institution of the Ministry of Interior. 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. National Institute for Environment - The National Institute for Environment (NeKI) is a background institution of the Ministry of Rural Development, and assists the Minister in the various duties of water management, environmental protection and nature conservation. NeKI has 12 regional branch offices, and is in charge of the strategies, policies and regulations regarding the management and exploitation of water resources.

NeKI also coordinates the planning and the implementation of national and EU projects. National Inspectorate for Environment, Nature and Water - The Inspectorate attends to administrational and water management matters, to analyses and consideration of law proposals in its field, and it supervises its 10 regional inspectorates as well. It coordinates international co-operations and takes part in the tasks connected to the EU integration. The regional inspectorates and two sub-offices are the 'green authorities' at first instance. The regional inspectorates are responsible for registration, monitoring, protection, conservation, reconstruction, rehabilitation, authorization and penalty processes regarding environment, nature and water in their assigned territory. WWF Hungary - WWF Hungary is the Hungarian arm of the WWF Network and was founded in 1991.

International Commission for the Protection of the Danube River (ICPDR) - The ICPDR is an International Organisation consisting of 14 cooperating states and the European Union. Since its establishment in 1998, the ICPDR has grown into one of the largest and most active international bodies of river basin management expertise in Europe. The ICPDR deals not only with the Danube itself, but also with the whole Danube River Basin, which includes its tributaries and the ground water resources Approved 2 - 5 m 16 10 - 50 m Creation of gravel banks Removal of sediment Planting Creation of fish spawn nursing places Awaiting results Yes Fish: Species composition,,,Yes,,,Awaiting results Invertebrates,,,,,, Fish: Species composition Invertebrates Adding sinuosity Séd-Nádor 2009 Consortium Hungarian Lowlands National No No Yes true Improvement Yes Substrate conditions,,,Yes,,,Improvement Substrate conditions László Mag 1470 1000 - 5000 k€ Séd-Nádor 2009 Consortium Séd-Nádor 2009 Consortium 47.107702,18.057858 László Séd-Nádor 2009 Consortium Mag Reduced pollution Creation of gravel banks,Removal of sediment,Planting,Creation of fish spawn nursing places,,Adding sinuosity, ,Reduced pollution,,Information provision,Consultation László Mag 109 100 - 500 k€ Séd-Nádor 2009 Consortium László Mag 5162 Improvement Yes Specific non-synthetic pollutants,,,Yes,,,Improvement Specific non-synthetic pollutants László Mag Séd-Nádor 2009 Consortium 2009-03-01Z 2454891.5 Complete The activity of the Nitrokémia chemical industry was recently terminated, but it's sewage waters left the Séd-Nádor stream along a 125 km long section polluted by toxic metals, which pose a significant environmental risk caused mainly by mercury, cadmium and lead. The aim of the project is to restore and rehabilitate the Séd-Nádor stream by removing the polluted sludge, creating structures in the streambed and by the recultivation of the banks and surrounding area. All interventions are based on an ecological and human health risk assessment.
