The Aqui-FR project aims at deploying groundwater resource modelling coupled with both flow
simulation and recharge estimation via the Surfex surface scheme (Masson et al. 2013). Aqui-FR is
based on the integration of a set of existing hydrogeological applications and generally developed in
connection with water managers. Today, Aqui-FR covers more than a third of the sedimentary
aquifers in France, karstic aquifers, and some basement aquifers. (Vergnes et al. 2020). It is used for
applications on past historical reconstitution, real-time monitoring of the aquifer situation, seasonal
forecasts and climate projections (Habets et al. 2019; Leroux et al. n.d.; Vergnes et al. 2020).
Seasonal forecasts have been evaluated over a 25-year period, and have shown a good capacity to
anticipate groundwater resources and in particular drought zones 6 months in advance, mainly for
forecasts covering the summer period, with particularly satisfactory results at the end of the summer
(Leroux et al. n.d.). Thus, since January 2020, seasonal forecasts are made in real time, and have
been used in particular to anticipate the droughts of 2020.


- A first step is to evaluate the predictions of groundwater-river exchanges, which could provide a useful prediction of minimum low flows.
- A second step will be to improve this potential by refining the simulation of river flows through the implementation of a homogeneous river network over the whole metropolitan territory. Initial work has been carried out with the RAPID routing model (David et al. 2011) and the RHT river network (Pella et al. 2000). The whole system must now be connected to the hydrogeological applications included in Aqui-FR.
- These improvements will be tested on the new operational forecasting system. Indeed, the seasonal forecasting system used, based on the Arpege atmospheric model (Batte and Deque 2016) evolves very regularly. The next system will integrate corrections for precipitation, which is particularly interesting for water resource forecasting.


- PhD in geosciences, hydrology or meteorology
- Environmental modelling skills
- Python programming skills, Linux system
- Knowledge of statistics and data processing
- Ability to work independently and as part of a team
- Experience in scientific writing for the valorisation of works in scientific journals

Work Context

The work will be carried out at the CNRM-UMR3589 (Météo-France/CNRS) in Toulouse, with a strong collaboration with the Aqui-FR research group, in particular with the Météo-France service operating these forecasts in real time, in order to ensure that diagnostics and development can be integrated in operational terms, with the hydrogeologist modelers (BRGM, CNRS, MinesParistech) both for the model aspects and for the links with the work carried out in parallel on the feedback from the 1st year of forecasting and on the development of a piezometric data assimilation, and finally, with the French Biodiversity Office which is funding the project.
