Description:
The objective of this postdoctoral project is to design and perform reactive tracer tests in highly instrumented observatories to address currently open questions about reactive transport processes in the critical zone. We will consider a range of reactions, including redox reactions, such as denitrification and iron-oxidation, possibly coupled with microbiological processes. The objective will be to compare field scale reaction rates to batch reaction rates, to assess the impact of flow rates and mixing processes on reaction rates, and to quantify the effect of subsurface reactive processes on river chemistry. Tracer breakthrough curves will be interpreted using reactive transport models developed by the Rennes team (https://reactivefronts-erc.univ-rennes1.fr/).
