Mixing and wave-driven transport in the surf zonePhD – Victor Loras Herrero
Dates: 2024 – ...
Host: SIAME.
Direction: V. Roeber, M. Delpey.
Summary - The PhD focuses on the numerical modeling of pollutant mixing and wave-driven transport processes in the surf zone. This is achieved using BOSZ, a phase-resolved Boussinesq-type model based on the Nwogu equations, which accurately captures non-linear and dispersive wave dynamics. Within the framework of the PhD, the model has been ported to a performance-portable version using the Kokkos library, allowing it to run efficiently on both CPU and GPU architectures. This performance gain enables the simulation of larger, more realistic coastal domains. A key goal of the project is the development of an extension module that incorporates an advection-diffusion equation, as well as the integration of Lagrangian particle tracking to represent solid pollutants or other similar tracers.
The final objective is to validate this extended version of the model using both laboratory experiments and real-world scenarios, based on historical data from the Basque Coast. To support this, digital elevation models (DEMs) are processed using GIS tools to generate model-compatible grids. Ultimately, the project aims to enhance the predictive modeling of pollution events in coastal environments.
