Par Cecile Marechal

Researcher in hydrodynamic/sediment transport modelling (M/F) - 2 years fixed-term contract

Context of intervention

The successful candidate will join the “Environmental Research and Innovation” (ERIN) department. With a team of more than 170 scientists and engineers from life science, environmental science, and IT science, the department has the necessary interdisciplinary knowledge and skills to tackle major environmental challenges our society is facing today: climate change mitigation, ecosystem resilience, sustainable energy systems, efficient use of renewable resources, environmental pollution prevention and control.


The candidate (m/f) will participate in the MOBISED project (MOBISED stands for Modelling the reMOBIlization of SEDiments and the release of associated contaminants), co-funded by the Luxembourg National Research Fund (FNR) and by the French National Research Agency (ANR). The project is part of the research cooperation network between Luxembourg and Lorraine region.

The investigations will focus on the remobilization of sediments in the River Orne, a small river historically affected by mining and industrial activities. The main objective is to understand and characterise the mechanisms involved in sediment remobilization and their consequences on water quality.

To achieve this goal, a multi-disciplinary approach is proposed involving (i) a precise and detailed characterisation of river sediments including physical, chemical and microbiological properties providing contamination nature and status, (ii) a detailed description of hydro-climatological characteristics and hydrodynamics prevailing in the river basin, (iii) controlled experiments of sediment re-suspension and high resolution sampling during several high flow events in order to obtain the distribution and composition of aggregates and contaminants in the water column, and (iv) the monitoring of the riverbed morphology and the modelling of sediment transport.

The candidate will join a multi-disciplinary research environment including remote sensing scientists, hydrological and hydraulic modellers, as well as experimental hydrologists.


One of the main strengths of the MOBISED project lies in the combination of quantitative and qualitative approaches to estimate the fate of pollution in river systems.

In this framework, the candidate will:

• be in charge of the hydrodynamic-sediment transport activities within the project, which includes the set-up and the development of the numerical model;

• develop methodologies for integrating quantitative and qualitative data in the model;

• implement and calibrate a 2D and/or 3D hydro-morphodynamic model (based on the Telemac hydroinformatic system) of a section of the River Orne (France);

• validate the results using field measurements.


The developed model will be used for predicting sediment transport and remobilization during several flood events.



The candidate should hold a PhD degree (or equivalent) in the domains of water sciences, environmental modelling or



• Experience in the set-up and calibration of hydrodynamic and sediment transport models.

• Expertise in interpreting hydrodynamic/sediment transport models and associated uncertainties.

• Good programming skills (Matlab, Fortran) are essential and experience with the Telemac Hydroinformatic system including the

sediment transport module Sysiphe will be considered as an asset.


The candidate must be fluent in English; knowledge of French is an asset.
