Job Summary :

The aim of this project is to understand the impact of wind-driven hydrodynamics on the distribution of clastic sediments in lakes. The project investigates 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 numerical model Delft3D to simulate wind-induced hydrodynamics and sediment transport/deposition in shallow to deep domain of lakes.

The post-doc researcher will examine some of the large lakes of the world, and will also explore the impact of past (e.g. Last Glacial Maximum, Holocene, historical, contemporary) significant water-level changes on the reorganization of the hydrodynamics and distribution of sediments with a focus on the lacustrine coastal domain.

This research offers original perspectives on (1) sequence stratigraphy of lacustrine basins, and (2) the fate of lake systems in the context of ongoing global climate change.

Job Description :

The post-doc researcher will design and run numerical simulations with Delft3D. Cases studies will be selected following discussion with the research group listed below, and results will also be interpreted together. The hired person will lead the writing of scientific papers linked to this project.

The main objectives of this project are:
- validate boundaries to the simulation of wind driven transport in lakes in Delft3D,
- characterization of the response of the global hydro-sedimentary dynamics to significant rise/fall in water-level, with a focus on the evolution coastal domain (backshore, foreshore, shoreface),
- for selected case studies, identification of source and sink zones for sediments, with a particular focus on contourites/sediment drifts and erosional surfaces,
- determination of the respective impact of wind-forcing, rates of water-level changes, sediment supply, seasonal ice formation, water column stratification, ...

A provisional list of cases includes the following large continental waterbodies: Lakes Chad, Turkana, Eyre (Kati-Thanda), Saint-Jean, Qinghai, Erie, Aral Sea, ...

This research is funded by the Initiative d’Excellence program of the University of Strasbourg. It will be conducted at Institut de Physique du Globe de Strasbourg, a joint research unit of CNRS & University of Strasbourg.
There, the work will be supervised by Dr M. Schuster and will involve Dr J.F. Ghienne.
This research is part of an international collaborative network involving:
Dr J.E.A. Storms (TU Delft, The Netherlands)
Dr H. van der Vegt (Deltares, Delft, The Netherlands)
Dr A. Nutz (Aix-Marseille University, France)
Dr M.S. May (University of Cologne, Germany)
