The goal of this project is to evaluate different open-source softwares to build a beach morphological evolution modeling system. The modeling system will couple four components: wave, current, sediment transport and bed evolution, with the objective to predict the beach morphological evolution at the intermediate timescale, typically one month. Three modeling systems, namely CROCO (a fork of ROMS), DELFT3D and XBEACH, will be evaluated by comparing predicted and measured bathymetries of the ECORS-Truc Vert'08 nearshore field experiment. A sensitivity analysis to wave-breaking and sediment tansport formula will be undertaken and a statistical analysis will be developed to analyze the relationship between the significant wave height and the predicted morphological evolution.
The position is opened to candidates having a master degree or an engineering degree for a duration of 12 months starting as soon as possible. The monthly net salary will be 1600€ depending on the candidate qualification (applicants with a PhD degree are also welcomed to apply). The recruited candidate will work at LEGI/University of Grenoble Alpes (Grenoble, France).
The recruited candidate will perform numerical simulations for the morphological evolution of the truc vert beach'08 field experiment using the three numerical models, CROCO, DELFT3D and Xbeach. The numerical set-up exists and have already been validated for the waves and hydrodynamics components.
The candidate should have a background in coastal engineering. A good knowledge in scientific programing using matlab/python and FORTRAN is required
The Laboratory of Geophysical and Industrial Flows (LEGI) is a fluid mechanics laboratory, composed of 120 people divided into 4 research teams and 5 departments, whose research covers a wide range of fields: renewable energies, environmental flows, aerospace applications.
LEGI's expertise is based in particular on an important experimental approach: more than 40 experimental benches, including large instruments (wind tunnel, wave channel, cavitation hydraulic channel, Coriolis rotating platform, etc. ) that require significant design, construction, installation and maintenance work as well as constant evolution according to the progress of research work.
