Tidal zones - Channel
This product includes Shom 3D digital data on tidal currents in the Channel in shapefile and geotiff formats. These digital files provide information on tidal current components (speed and direction) on an hourly basis (6 hours either side of high water for a reference port), and for two typical tidal coefficients (45 and 95). Cherbourg is taken as the reference port. Three layers are available: Surface; mid-depth; and sea-bed.

Sources: The 3D 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.
