Applicability of the Blue Wave to the Canal from Villiers to Beaulieu

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