Institution : UMR 7329 Géoazur / Mediterranean Institute for Risk, Environment, and Sustainable Development (IMREDD)
Contract Type: Fixed-term (36-month contract)
• Category: A
• Workload: Full-time
• Location: UMR 7329 Géoazur, 250 Rue Albert Einstein 06905 Sophia Antipolis / IMREDD, Technopole Nice Meridia 9, Rue Julien Lauprêtre 06200 Nice
Missions
In synergy with the research team (Geoazur) and IMREDD, local partners and stakeholders managing water resources (Régier Eau d’Azur, the local water utility), and another postdoctoral researcher working on hydrodynamic modeling, you will develop and apply an operational methodology with adaptive complexity depending on processes and challenges. Thus, within this position, you will contribute to an ambitious project where your inputs will:
• Qualify and quantify the dynamics of sediment pulses
• Identify processes driving extreme sediment-laden floods at the watershed scale
• Identification of hydrodynamic forcing’s responsible for sediment dynamics in the study areas
• Analysis of conditions triggering the movement of different sediment classes
• Analyze morphological changes resulting from these extreme events
• Evaluate the effect of recurring floods and droughts on braided riverbed structuring
• Identify feedback mechanisms related to these transformations on riparian systems and water resources
• Model hydro-geomorphological changes at different spatial and temporal scales with modular process complexity: develop and optimize numerical modeling experiments using deterministic, physically-based calculation codes
• Explore the impacts of extreme events amplified by climate change
• Propose future evolution scenarios by integrating various assumptions, which you will test
Required Qualifications
You hold a PhD in hydrology, geomorphology, sedimentology, or numerical modeling, with expertise in fluvial systems and the analysis of extreme events.
Your field of expertise covers several of the following fields:
• Concepts of hydro-geomorphology.
• Hydraulic modeling, with initial experience in sediment transport modeling (cohesive, non-cohesive, or mixed; 2D or 3D).
• Advanced physically-based software and calculation codes (e.g., IBER, TELEMAC 2D, HEC-RAS).
• The use of computing clusters and GPUs.
• Statistical approaches and programming tools (Python, MATLAB, etc.).
• You have a proven ability to work in multidisciplinary teams and experience in publishing scientific articles.
You are comfortable and enjoy working in a transdisciplinary team. You are a dynamic person and comfortable with communication, preparing and conducting field campaigns, including sampling and measurements. Proficiency in French is positively evaluated.
