Hydrological information provided from this site is a service of the Hydrological Observatory of Athens, operated by the National Technical University of Athens. It is an evolution from the hydrometeorological network METEONET and provides access to a single database, which will gradually incorporate further stations and hydrological measurements, including the ones of the Experimental Basin of Athens - XBasin. Here you will be able to locate hydrometeorological stations on the map, download historic time series and use advanced applications for a statistical analysis of selected hydrological data.
