Tidal currents on French coasts (Channel/Atlantic)
This product includes all Shom digital files for tidal currents on mainland French coasts (Channel and Atlantic coasts) in mesh format. These digital files indicate surface tidal current components, hour by hour and for two typical tidal coefficients (45 and 95) and maximum current speeds for a mean spring tide. Brest is taken as the reference port for viewing purposes. The current points included in these files correspond to the arrows shown on current atlases.

Sources: The tidal currents included in the files are taken from tidal wave propagation digital simulation models focusing on a maritime environment. The models cover a larger geographic footprint than the data files, which match the cover of the corresponding atlases. The results for the boundary areas of models are less precise than results nearer the centre of the scope modelled, for this reason, the geographic scope of the files was reduced to exclude all lower quality data. Validation: Data are then subjected to several validation stages: adjusting physical and numerical parameters, adjusting the models to in-situ measurements, adjusting the models to each other to ensure that overlap areas coincide, interpolating using an looser even mesh and removing all overlap to obtain data from the digital solution; data with the highest level of spatial resolution is retained in overlap areas.
