Data

European streamflow data and where to find it

A new catalogue and database of over 17,000 European river catchments facilitates the work of researchers in the field of hydrology. The EStreams project, carried out at Eawag, provides hydrological and meteorological data as well as information on the landscape of the river regions. The records go back up to 120 years.

For UN Agenda: data gaps detected in 193 countries

To make informed decisions, governments and international organisations need data. The United Nations has been analysing the global availability of such data together with ETH Zurich. This has brought to light some surprising insights.

Four billion people estimated to lack safe drinking water services

More than half of the global population were estimated to lack safely managed drinking water services in a recent study lead by Eawag researchers. This is shown in a global map that researchers compiled using machine learning based on data from household surveys and data derived from Earth observations.

Stranger Danger and extremist online communities

New EPFL research has found that the exchange of comments between members and non-members of fringe communities (fringe-interactions) on mainstream online platforms attracts new members to these extremist groups. It has also suggested potential ways to curtail this growth.

Lasers for more road safety

This winter, the SLF tested a new system to better assess the risk of avalanches to traffic routes. The results are promising and should allow roads and railroad lines to be closed for shorter periods of time in the future when conditions are tight.

Opening a window on environmental phenomena

Data collected by satellites, drones, radars and microscopes provide a goldmine of information to better understand our environment. And when these data are coupled with artificial intelligence (AI), they can unlock the secrets of phenomena taking place at all levels.
