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 observatory includes:
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 687 km2.
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.
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.
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).
An on-line platform (http://hoa.ntua.gr/) providing access to the information collected from HOA and processed by CHI.

The Water4All Partnership - Water Security for the Planet - is a funding programme for scientific research in freshwater. It aims to tackle water challenges to face climate change, help to achieve the United Nations’ Sustainable Development Goals and boost the EU’s competitiveness and growth.

It is co-funded by the European Union within the frame of the Horizon Europe programme (a key funding programme for research and innovation). The Partnership duration is for seven years from 2022.

The Water4All objective is to enable water security at a large scale and in the long term. Its goal is also to tackle water issues in a holistic frame. 

All forms of life on earth need water. All human activities operate with this resource. Water is part of our everyday life. It is also integrated within urban and countryside landscapes. It is one of the most valuable elements we share with plants and animals.

These simple facts must be kept in mind to understand the Water4All ambition.

This resource is weakened in many places due to climate changes, and human habits. We know that we can improve the way we use water. Everyone has a role to play and especially the scientific research community.

Scientific research is the heart of the Partnership as It is a powerful tool to improve knowledge on preserving, restoring, and managing this essential resource. 

International cooperation is also needed as water has no borders on Earth and runs from one country to another.

Water4All brings together a broad and cohesive group of 90 partners from 33 countries in the European Union and beyond. This consortium gathers partners from the whole water Research, Development and Innovation (RDI) chain.
