World desertification and drought day

The rainfall, hydrological and hydrogeological data analysed continuously by info- secheresse.fr already point to a summer of high tension on the drought front.
Against this backdrop, Saur, via its subsidiary imaGeau, is unveiling new features for the application (display by natural perimeter, 40% more monitoring points).
In particular, the platform has been enhanced with a drought forecasting function – powered by AI
– to help all stakeholders manage this risk more effectively.

Info-sécheresse: a concrete expression of Saur’s commitment to the responsible use of data

Faced with the risks of recurring drought and water stress, in 2020 Saur, via its subsidiary imaGeau, launched info-secheresse.fr, a free digital platform providing free access to qualified and spatialised drought data for the French départements.

It brings together and continuously interprets, on a single site, all the public data from three key disciplines in the analysis of drought phenomena: meteorology, hydrology and hydrogeology. This initiative, with its unique method, makes the most of all these public data bases to find out in real time how water resources are evolving.

This is the first system in France to highlight the worsening drought situation in the country.

"The data we are collecting confirms that drought episodes will continue to increase in frequency over the coming years. To help us better anticipate and manage this risk, we are making new technical and digital resources available to everyone on the Infosécheresse.fr platform. This initiative demonstrates our commitment to protecting water. "

An enhanced system in 2021 to meet the needs of players on the ground

As of today, the site offers new functionalities:

– New drought indicators to take account of the impact of heat waves on water resources;
– A wider monitoring perimeter: 4,000 additional monitoring points, particularly small watercourses, bringing the number of points monitored to over 10,000;
– A clearer display of the drought phenomenon. In addition to a representation by administrative entity (departments), the platform offers a more coherent reading of the drought by natural perimeter: catchment areas and water tables.

For the first time in France, interactive drought risk maps for surface water tables are being made available on a daily basis.

The big news for the service this year is also the launch of a predictive function, aimed at professionals, on a subscription basis. Thanks to Artificial Intelligence and Machine Learning algorithms, this new feature can provide forecasts for:
– Water table levels,
– River flow,
– Meteorology.
For each forecast horizon, confidence indices and statistical metrics are communicated to users to enable them to understand the evolution of the drought risk several weeks in advance.
