Objective
The general objectives of FLUXMANCHE are to improve the knowledge about the hydrodynamics of the Eastern Channel, and to estimate the water and particle fluxes across the Straits of Dover.
A study has been undertaken to obtain, through an interdisciplinary approach, a better knowledge of the dynamics of the eastern Channel and the transport of water and associated materials to the North Sea.
New models have been developed to understand and predict water circulation in the area, on different space and time scales. Forced y a 2-dimensional model of the continental shelf, a 2-dimensional model of the Channel gives instantaneous and long term water flows and computes fluxes of suspended and dissolved matters. A 3-dimensional model of the eastern Channel and southern North Sea has also been built, and exploited in the case of the Strait of Dover.
Experiments have been carried out on rotating tables equipped with a schematic cylindrical basin, in the field of coastal currents with and without density gradient. The modelling is supported by current measurements (high frequency radar, and acoustic Doppler current profiler) and remote sensing in the Dover Strait, and also spacetime observations of the distribution of radiotracers released by the treatment plant at La Hague.
Together with thesephysical approaches, an intensive field measurement programme has been performed, in order to obtain a better estimate of the fluxes of suspended particulate matter and chemicals transferred to the North Sea.
In the hydrodynamics part, the development of a number of models is to be combined (first two 2-d models, then a 3-d model, on decreasing spatial scales) with measurements of the currents in the Straits of Dover (by radar, on the surface, by current recorders and acoustic doppler current profilers at depth) and information derived from the space-time distribution of radioactive tracers from their source onward. Coastal processes modulating the fluxes at the interfaces between the water masses are the subject of an experimental study with a reduced model.
Particle fluxes across the Straits of Dover will be estimated from the results of the hydrodynamics studies and several measurement series of the suspended particles concentration and the levels of chemical substances, completed by remote sensing from aircraft.
