Enhydris: A free database system for the storage and management of hydrological and meteorological data
A server software offering a database system for the storage and management of hydrological and meteorological data.
Enhydris (Ενυδρίς) is a database system for the storage and management of hydrological and meteorological data. It allows the storage and retrieval of raw data, processed time series, model parameters, curves and meta-information such as measurement stations overseers, instruments, events etc.
The database is accessible through a web interface, which includes several data representation features such as tables, graphs and mapping capabilities. Data access is configurable to allow or to restrict user groups and/or privileged users to contribute or to download data. With these capabilities, Enhydris can be used either as a public repository of free data or as a fully secured – restricted system for data storage. Time series can be downloaded in plain text format that can be directly loaded to Hydrognomon (http://hydrognomon.org/), a free tool for analysis and processing of meteorological time series.
Enhydris is free software, available under the GNU Affero General Public License, and can run on UNIX (such as GNU/Linux) or Windows.

Known Enhydris Installations
- The openmeteo.org/db, the international, public database with free hydro-meteorological data is an Enhydris-powered database with data available exclusively under free licenses such as Creative Commons, where anyone will be offered the possibility to upload their own data.
- The Hydrological Observatory of Athens (http://hoa.ntua.gr/), a network of ten (10) automatic meteorological stations and four (4) flow measurement stations installed at the greater area of Athens.
- The Hydroscope project is a national Greek database of hydrological and meteorological data, featuring a distributed installation of Enhydris: each participating organisation keeps its data on its own server, but all the data are accessible through a common portal (http://hydroscope.gr/)
- The Athens Water Supply Company (EYDAP) uses Enhydris (currently on its intranet only) to manage and store its data. The information system is at: http://itia.ntua.gr/eydap/db/
- WQ DREAMS (http://wq-dreams.eu/) is a database and a web application designed to store and manage water quantity data reported to the European Environmental Agency. All data are related to regions in Europe, mostly at River Basin District level.
