Résumé

The AquiFR project aims at taking benefits of existing groundwater modeling applications used bystakeholders to develop new products in order to provide useful information for water resourcesmanagement. Indeed, it aims at providing forecasts of the groundwater resources at10 days aheadupto seasonal scale. In its present form, the AquiFR system includes 3 hydrogeological modelscovering 8 multilayers sedimentary aquifers and 10 karstic aquifers. These applications wereassembled within a coupling system facilitating the parallel computation and coupled to a land surfacemodel used in the French numerical weather model that provides the recharge. The whole system isexpected to run operationally at Meteo France. To do so, a real time application will be run daily forcedby an analysis of the observed atmospheric conditions. This real time simulation will then be able toprovide initial conditions for the forecasts. Ensemble 10-day forecast will then be run daily, andseasonal forecasts will be run monthly. The monitoring and the forecasts could be compared to thelong term reanalysis of the groundwater that is being built by using an atmospheric reanalysis.
