Modélisation marine et côtière
la modélisation marine et côtière est appliquée à l’analyse des processus hydrodynamiques régissant les environnements côtiers et offshore. Des simulations numériques sont utilisées pour étudier les interactions entre la houle, les courants et les marées avec les littoraux naturels et les systèmes aménagés, afin d’appuyer la planification côtière, le développement portuaire et les études d’infrastructures marines.
Hydrodynamique côtière et marine
We deliver state-of-the-art numerical modeling of coastal hydrodynamics and wave transformation, from offshore conditions to the nearshore and shoreline interface. By coupling spectral wave propagation models with free-surface 2D/3D hydrodynamic solvers, we reproduce the key processes governing coastal response—shoaling, refraction, diffraction, breaking, wave–current interactions, tides, and wind forcing.
This integrated approach supports coastal flooding and marine submersion assessments, the dimensioning of maritime structures, and coastal protection and resilience studies, providing scientifically robust metrics for design conditions, hazard levels, and mitigation performance under present and futurs scenarios.
Houle, courants et processus de marée
Numerical studies increasingly focus on 2D and 3D hydrodynamics to capture the combined influence of tides, background/general circulation, and wind forcing on coastal and marine systems, from open coasts to semi-enclosed basins. These modelling frameworks resolve water levels, depth-averaged and/or vertical current structures, and their spatio-temporal variability under both operational and extreme conditions.
When relevant, the hydrodynamic core is coupled to a wave-propagation model to account for wave–current interactions, including wave-induced currents (via radiation-stress gradients) and Stokes drift, improving the representation of nearshore transport and hydrodynamic forcing.
This integrated approach supports the assessment of coastal response, sediment pathways, and loading conditions required for engineering design, shoreline management, and the performance of marine structures.
Agitation portuaire et hydrodynamique des bassins portuaires
la modélisation portuaire se concentre sur la pénétration de la houle, la résonance des bassins et les processus de circulation au sein des bassins fermés et semi-fermés. Des simulations numériques sont utilisées pour évaluer les niveaux d’agitation, les conditions d’amarrage et l’opérabilité des navires sous différentes conditions d’état de mer et de marée.
Results support navigation safety, harbour performance and the optimisation of port layouts, contributing to informed decision-making for port design, expansion and coastal protection measures.
