Missions

The objective of this project is to understand the impact of wind-driven hydrodynamics on the distribution of clastic sediments in lakes. This project explores the concept of "wind-driven waterbodies" as defined in Nutz et al. (2018; https://doi.org/10.1007/s10933-016-9894-2).

This project is based on the use of the Delft3D numerical model to simulate wind-driven hydrodynamics and sediment transport/deposition in lakes.

The postdoc will examine some of the world's large lakes and also study the impact of large water level changes in the past (e.g., Last Glacial Maximum, Holocene, historical times, recent period) on the reorganization of hydrodynamics and sediment distribution, especially in the coastal lake domain.

Activities

The postdoc will design and perform numerical simulations with Delft3D. The case studies will be selected after discussion with the research group mentioned below, and the results will also be interpreted together. The person hired will lead the writing of scientific papers related to this project.

The main objectives of this project are to:
- validating the limitations of the simulations with Delft3D,
- characterization of the response of the global hydro-sedimentary dynamics to a significant rise/fall in water level, with a focus on the evolution of the coastal domain (backshore, beach, foreland)
- identification of source and sink areas for sediments, with a particular focus on contourites and erosion surfaces
- determination of the respective impact of wind forcing, water level change, sediment supply, seasonal ice formation, water column stratification, ...

Work Context

This research will be conducted at the Institut Terre e Environnement de Strasbourg.
The Institut Terre et Environnement de Strasbourg (ITES) (UMR7063) started on January 1, 2021 under the supervision of CNRS, the University of Strasbourg and ENGEES. This new UMR is based on the 4 disciplinary pillars of study of the Earth and its surface environment: Hydrology, Geochemistry, Geology and Geophysics.
The research will be conducted within the Geology team, in the group studying lacustrine sedimentary systems. This project will be conducted in partnership with an international team (TU Delft, Deltares, AMU, U-Melbourne, U-Cologne).
