Permanent research position in experimental hydraulics applied to river morphodynamics processes, Lyon, France
Closing date: February 15, 2012
Cemagref/Irstea conducts research in support of public policy and in partnership with industry. It employs 1,600 people on 9 sites in France. Understanding sediment dynamics in rivers is a major scientific challenge.
The Hydrology-Hydraulics research unit (HHLY), in which the applicant will be recruited, develops research and expertise in the field of sediment transport and river morphodynamics.
The recruited researcher will be primarily involved in the HHLY experimental facility, designed to develop measurements and detailed studies of bedload and suspended load and morphodynamic processes at a scale representative of rivers. Eventually, he/she will support the scientific management of the hydraulics laboratory including collaborations related to this new experimental platform (starting by the end of 2012). His/her work will focus on experimental studies of river morphodynamics in order to develop a quantified approach to the dynamics of streams.
The three main types of sediment transport (bed load, suspended load, wash load) and their possible interactions can be addressed by focusing on extreme events, bed clogging, large bedform stability, effects of vegetation, or influence of floodplains, etc. He/she will develop or improve laboratory techniques for the measurement of sediment transport (turbulence, particle velocity …). Understanding of processes will be based on a detailed description of hydrodynamic characteristics and interactions between flow, sediments (fine and coarse) and vegetation for different configurations that can be observed in nature. A formalization and generalization of these processes will be used for field observations and numerical modelling.
Main studies will focus primarily on the dynamics of gravel bars, banks, and cut-off channel including the influence of fine material transport. One objective will be to provide recommendations for revitalization operations and for maintenance of some dynamics for riverine water bodies. Laboratory experiments will be conducted in close connection to field activities conducted by the research unit. Obtained results will be eventually used for the development of numerical models to be validated thanks to laboratory experiments and tested in situ. Abilities.Applicants must hold a doctoral degree and publications in the field of sediment transport and river morphodynamics.
He/she should have some background in experimental research in a hydraulics laboratory, and if possible some experience inexperimental research with moveable bed. He/she should have some knowledge in metrology (instruments and measurement techniques in hydraulics laboratory, measurement uncertainty analysis), and an ability for team work, for the supervision of students, for the management of projects, and for publication in international journals. Ideally, the applicant should handle programming languages and have some experience in numerical modelling as well as in field experiments and in rivergeomorphology. Basic knowledge of French is required. For more information, contact J-B. Faure.
