Post-doctoral fellowship on surface water and groundwater interaction

Applications are invited for postdoctoral researchers within the project "Caractérisation des échanges Rhône-nappe et des effets d'autoépuration des berges" funded by the French Water Agency Rhône Mediterranée Corse.

The island of Barthelasse, the largest river island in Europe, hosts 2 pumping areas that supply drinking water to nearly 180000 inhabitants in various agglomerations on the left bank of the Rhone near Avignon, France. Due to its location, the aquifer is very vulnerable to the river. The Rhône Ventoux water management operator, which is in charge of the management of this aquifer in collaboration with the Rhône Mediterranee Corse Water Agency, is concerned about the risk of pollution of the groundwater by the river Rhône or its backwaters. As part of this project, the HYDRO research group of the UMR EMMAH (University of Avignon) will conduct a study on the transfer modalities between the river Rhône and the groundwater water by means of natural tracing. Several points of observation of the water table as well as the Rhone are already equipped with sensors for the monitoring of water depth, temperature and electrical conductivity. This long-term monitoring will be supplemented by in situ short time experiments for isotopic monitoring using a laser spectrometer (18O, 2H) or by taking samples (13C, 3H). The objective is to determine the distribution of the solutes transit times from the river Rhone to the aquifer for different observation points and in different hydrological conditions of the Rhone and pumping exploitation.

From the experimental point of view, the role of the candidate will be to organize the physicochemical and isotopic database, to control sensors and retrieve data, and to organize field campaigns. From the acquired data, the work will then consist of implementing 1D and 2D-3D analytical transfer models aimed at identifying mixing proportions and establishing the distribution of transfer times between the river Rhône and the aquifer. The results will be published in international scientific journals.

Deadline for applications: 01/09/2018 (position to be filled on 01/10/2018)
