Seminar

Title : Toward multi-scale modelling of the whole hydrosphere: Concepts, applications and diagnoses
Name of the speaker : Eric Deleersnijder
Affiliation : Université catholique de Louvain, Belgique
Laboratory organizer : LSCE
Date and time : 20-05-2010 11h00
Location : LSCE - ORME piece 17C
Summary :

The processes taking place in the hydrosphere (sea ice , oceans, shelf seas, estuaries, rivers, etc.) are characterised by a wide range of space- and time-scales. Though it is not possible to explicitly simulate all of them, it is our conviction that widening the range of resolved processes, as opposed to parameterised or ignored, will prove fruitful in the long run. To do so, new models are needed that are capable of enhancing the resolution when and where necessary and representing a large number of physical, chemical and biological processes. Such models are being developed by various teams over the world, one of them being based in Louvain-la-Neuve, Belgium. Their model (SLIM ) solves the governing equations by means of the finite-element method on 2D or 3D unstructured meshes. The current status of SLIM will be briefly presented, as well as the developments planned in the future. Some applications will be reported on, in particular those pertaining to the land-sea continuum of the Scheldt River (France, Belgium, The Netherlands). Finally, diagnoses of numerical results having recourse to the CART tool box will be discussed.
