Open PhD position
The candidate will systematically investigate the impact of (a) heterogeneities in the hydraulic (e.g., in the sediment permeability) and biogeochemical (e.g., in the reaction rates) properties of the hyporheic zone and (b) of the temporal fluctuations in the fluvial regime on the solute transport, mixing and reaction dynamics with special attention to their behavior in the hyporheic zone. The candidate will conduct the investigation mainly through the lens of suitable numerical simulations (Eulerian and/or Lagrangian approaches). The candidate will interact with other members of the HYPOR research team working on the theoretical development of physics-based upscaled models. Visiting period to international collaborators will be strongly encouraged. Results will be published in international scientific journals, newsletters, and social media outlets, and the work will be presented at international conferences and project meetings.

Open PhD position
In the context of HYPOR project, the candidate will develop upscaled descriptions of the transport, mixing and reactive dynamics linked to the mechanisms and features that govern large-scale behaviors. In particular, the upscaled models will be linked to (a) heterogeneities in the hydraulic (e.g., in the sediment permeability) and biogeochemical (e.g., in the reaction rates) properties of the hyporheic zone and (b) temporal fluctuations in the fluvial-aquifer regime. While the focus is on the theoretical development of upscaled descriptions, the candidate will interact with other HYPOR research team regarding the numerical simula=ons and experimental data. Visiting period to international collaborators will be strongly encouraged. Results will be published in international scientific journals, newsletters, and social media outlets, and the work will be presented at international conferences and project meetings.

Open Postdoctoral position
In the context of HYPOR project, the candidate will systematically investigate the impact of (a) heterogeneities in the hydraulic (e.g., in the sediment permeability) and biogeochemical (e.g., in the reaction rates) properties of the hyporheic zone and (b) of the temporal fluctuations in the fluvial regime on the solute transport, mixing and reaction dynamics with special attention to the hyporheic dynamics. The candidate will conduct the investigation mainly through the lens of suitable numerical simulations (Eulerian and/or Lagrangian approaches). The candidate will interact with doctoral student working on the same topic. Moreover, as the numerical simulations will support the theoretical development of upscaled descriptions of solute transport, mixing and reaction dynamics in rivers the candidate will interact with other members of the HYPOR research team working on the theoretical development of physics-based upscaled models. Visiting period to international collaborators will be strongly encouraged. Results will be published in international scientific journals, newsletters, and social media outlets, and the work will be presented at international conferences and project meetings.
