Fig.2 The main drainage areas in Europe. Since the Czech republic is at the border of three drainage areas and it doesn!t recieve any water from big rigers flowing into the state from abroad, it has to rely fully on the water from rains and so it is called "the roof of the Europe even though its mountains are far from highest in Europe

The head office and centralized workplaces of the institute, including the data processing, telecommunication and technical services, are located at the Institute's own campus in Prague. The Institute is made up of free specialized sections: (meteorology and climatology section, hydrology section, and air quality section) with two support sections (finance and administration and Information technology (IT) section), and finally, the director section.
