Aqui-FR : a national multimodel hydrogeologic system
The Aqui-FR project aims at providing monitoring and forecasts of the groundwater resource in France, as well as long term projections. To do so, the Aqui-FR project relies on existing hydrogeological applications.

The AquiFR project aims at taking benefits of existing groundwater modeling applications used by stakeholders to develop new products in order to provide useful information for water resources management. Indeed, it aims at providing forecasts of the groundwater resources at from 15 days ahead upto seasonal scale.
To do so, up to now 3 hydrogeological models (MARTHE from BRGM, MODCOU / Eau-dyssee from MINES ParisTech, and a conceptual model for the karstic aquifers GARDENIA) covering 8 multi-layers sedimentary aquifers and 10 karstic aquifers in France are included.
These applications were assembled within the coupling system OpenPalm facilitating the parallel computation and coupled to the SURFEX land surface model used in the French numerical weather model that provides the recharge.
The whole system is expected to run operationally at the french weather service, Meteo France. To do so, a real time application will be run daily forced by an analysis of the observed atmospheric conditions. This real time simulation will then be able to provide initial conditions for the forecasts. Ensemble 10-day forecast will then be run daily, and seasonal forecasts will be run monthly. The monitoring and the forecast could be compared to the long term reanalysis of the groundwater that is being built by using an atmospheric reanalysis beginning in 1958.
In a way, Aqui-Fr should be an improvment of the SIM (Safran/Isba/MODCOU) hydrometorologic system that is currently used at Meteo-France.
