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. http://www.ovf.hu/ 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. http://neki.gov.hu/ 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. It performs environmental monitoring, status and impact assessments, administrates the national network for hydrological, hydrographical, hydrogeological and quality measurements of public waters. NeKI also coordinates the planning and the implementation of national and EU projects. http://www.orszagoszoldhatosag.gov.hu/index en.php 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.
