Groupe de travail MathOcéan

Plan du site

Présentation

Le Groupe de travail MathOcéan a pour but d'impulser des collaborations à l'interface entre les mathématiques et l'océanographie physique (dynamique des géofluides, vagues, ondes internes, courants océaniques, etc). Il est organisé conjointement par des laboratoires bordelais et toulousains avec le soutien des projets ANR Bond et Dyficolti. Il s'appuie principalement sur des rencontres bimensuelles alternativement à l'Institut de Mathématique de Bordeaux et à l'Institut Mathématique de Toulouse.

Tandem and Defi Littoral: tsunami school (Bordeaux, 25-29 avril)

Conference website
The 2016 school on tsunamis is the result of the synergy between the participants to the PIA TANDEM research program, and of the research groups revolving around the MathOcean initiative, which has benefitted of the funds from the CNRS call DEFI LITTORAL. It will take place in the conference room of the Institut de Mathematics de Bordeaux (building A33 of the applied science campus), in the week April 25-29, 2016. The aim of the school is to share the know how available within the TANDEM project and the MathOcean group with young researchers and students aiming at a career in fields related to the study of tsunamis. The classes offered cover all the aspects going from the generation of tsunamis, to their propagation, to their impact on the coast. Modelling by means of appropriate partial differential equations, as well as the proper numerical treatment of these equations, as well as field aspects are covered by the courses. Two more general key notes are also foreseen, one dedicated to alert systems, the other to the numerical study of real tsunami events. All talks will be in english. The school benefits form the funding of the PIA TANDEM, of the CNRS call DEFI LITTORAL, and of Inria.There is no registration fee, however the number of participants is limited so if you are interested in attending you must register (see How to attend page for details).
