Context

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.

The different temporal scales of the Aqui-FR applications: Historical analysis (from 1958 to nowadays, real time monitoring, 10-day forecast, seasonal forecast and climate projections

In a way, Aqui-Fr should be an improvment of the SIM (Safran/Isba/MODCOU) hydrometorologic system that is currently used at Meteo-France.

Progress report

Since july 2016, 8 applications from MODCOU/Eau-dyssée, 5 applications from Marthe et 6 karstics applications from GARDENIA are included in Aqui-FR.

Exstension du projet Aqui-FR en Juillet 2016 — Extension of the hydrogeological layers included in Aqui-Fr in July 2016.

All these applications are running simulteanously and are using the water fluxes computed by the Surfex land surface model.

The Aqui-FR system is built on the dynamic coupling system openPALM. The scheme below shows the OpenPALM structure of Aqui-FR: each model has its own branch that runs in parallel ( Gardenia in green, Marthe in blue and Eau-dyssée in brown). The 3 hydrological models are connected to a water balance module that provides the water flux estimated by Surfex. Then the results are transmitted to a module (in dark green) that collect the data and will allow some retroaction with the soil moisture.

Some results

Althoug the full post-processing of Aqui-FR is still being developped, some preliminary results are presented to illustrate some possible outputs.

Charge piezometrique — Map of the piezometric head simulated on January 22, 2001 on the overlaying layers of Aqui-FR, together with the position of the piezometric wells in northen France.
