Site Description
The Hydrological Observatory of Athens (HOA) is operated by the Centre for Hydrology and Informatics (CHI) of the National Technical University of Athens (NTUA). It is located in the region of Attica, covering the greater Athens area and the Rafina basin. The region of Attica is characterized as a Mediterranean eco-region, which includes three main land use types: urban, peri-urban and rural. Forests are limited to the mountainous areas of Parnitha, Penteli and Ymittos, which are frequently threatened by devastating wildfires, affecting the local ecosystems, hydrology, soil erosion and climate conditions. The hydrographic network is fragmented, mainly consisting of small coastal basins and streams. The most important water body is river Kifisos, which is a heavily modified water body running through a heavily urbanized environment.

Purpose
Environmental monitoring, Basic and applied research The Hydrological Observatory of Athens (HOA) was founded in 2005 by the Centre for Hydrology and Informatics (CHI) of the National Technical University of Athens (NTUA). It includes: 1) A monitoring network of 11 fully-automated hydrometeorological stations, 3 conventional rain gauges and 4 fully-automated streamflow gauges in the broader Athens area, covering an area of approximately ~700 km2. 2) An “experimental” catchment (X-basin) in Eastern Attica, covering an area of 15.18 km2. The X-basin is a small catchment used for basic research, which is integrated in the monitoring network of HOA. 3) An “operational” catchment (Rafina basin) in Eastern Attica, covering an area of 127 km2. The Rafina basin is a flood prone basin used for applied research. It includes the X-basin and it is integrated in the monitoring network of HOA. The FLIRE Decision Support System, for the integrated risk management of floods and fires, operates in this catchment. 4) Special monitoring equipment: 1 weather radar used for storm tracking, 1 disdrometer used for the investigation of rain drop size, 1 mobile van equipped with instruments for on-site measurements (analysis of hydrometeorological, hydrological, hydrochemical and hydrobiological parameters). 5) An on-line platform (http://hoa.ntua.gr/) providing access to the information, which is collected from HOA and processed by the CHI team. The on-line platform provides various services for academic and non-academic end-users: raw data from HOA stations, charts and maps for various hydrometeorological parameters in the Attica region, automatic reports on rainfall events, weather highlights and bio-climatic indicators for the greater Athens area.
