About hydrological information
Hungarian Hydrological Forecasting Service daily receives hydrological data from Hungarian and other European hydrological services. Based on these data graphs, maps and tables are produced to present actual hydrological conditions on the Danube basin. All stations important for catchments, water courses, water bodies as well as stations needed for foreacasts are involved in data processing. Graphs present 6-hour water level data series about last 30 days.
