ALOP-Colloquium with Prof. Dr. Bijan Mohammadi, Montpellier University

3. May 2021 / 16:00 - 17:00

On Monday, May 3, 2021 at 16:00 c.t. Prof. Dr. Bijan Mohammadi, Montpellier University, will present his recent work at our colloquium.  He will speak about

Variational nearshore dynamics 


Minimization principles are used in fluid-structure coupling to model sandy sea beds  evolution.The sandy bed is seen as a structure with low stiffness. We start with a model problem featuring the behavior of the coupling.Then water motion in shallow domains is described by the Saint Venant equations.This coupling bringing the bottom sea changes is based on the assumption that the bed adapts  to the flow in order to minimize some energy quantity togetherwith  minimal  sand transport.  The choice of the functional permits to include different physical quantities one think to play a role in the bottom morphodynamics.Hence, the approach is also a tool for validating different modelling hypothesis.We also present tentative  direct and reverse uncertainty propagation procedures under the constraint of keeping the computational costcomparable to deterministic simulations.The different ingredients will be illustrated through coastal engineering applications.  


The presentation will take place via Zoom. A link will be email prior to the event.
