Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

To summarise, the main objective of the present project is to build on the exploratory work that has been done under the auspices of UCL's FSR to develop an ocean model that will be based on an adaptive, unstructured grid, will rely on the finite element method and will resort to parallel computing algorithms to solve the governing equations. The model will include: - an embryonic unstructured-grid sea-ice component, - state-of-the-art parameterisations of subgrid-scale processes, - a flexible vertical discretisation system, - various advection schemes, - an elementary sea-ice data assimilation system. The model will be able to simulate the circulation in the World Ocean for studying the Earth's climate system, and will also be tested for a range of geophysical flow problems, including - the assimilation of sea-ice data, - circulation in the shelf break region, - representation of an extended range of space and time scales, - exploration of an extra-terrestrial oceanography problem. All aspects of the research work will be carried out in an open-source mode, relying on the close collaboration with colleagues outside UCL.
