Applicability of the Blue Wave to the Canal from Villiers to Beaulieu
The Blue Wave is a locking structure that allows simultaneous navigation in both directions of navigation, without stopping in most cases, and at a speed depending on the local topography.
Its principle has been described in an issue of PIANC Bulletin, N°108, september 2001.
It could be used, in lieu of a set of locks, on a Canal which is presently being improved to CEMT Class Va, far upstream from Paris, the Canal from Villiers to Beaulieu (Petite Seine, France).
It is possible to form 10 reaches of 1,000 m each, separated by doors (mitre or valve). The depth available in the existing borrow pits is sufficient for the navigation of the project boats, which have 31.9 m2 of wetted section.
By using the existing pits, which were dug in advance for improvement of this waterway, the structure very faithfully respects the current levels of these bodies of water, which avoids costly measures to restore the water table. In addition, the 2 upstream gates being non-overtopping, the non-overtopping dykes only total 2 km, instead of 16 km in the lock option.
These two points confirm that the proposed solution is more respectful of the environment and landscapes than the lock option. Thus, since the set speed of the concept is practically the optimum speed permitted by the cross-section of the canal, it can be said that the site of the Canal from Villiers to Beaulieu is optimal for the application of the Blue Wave principle.
