I am surprised that they have not used either compressed air to liquify and wash away the sand or even a water jet. The other thing they might do is to dig a big and deep hole in front of the bow but leave sufficient material to keep the canal out, when it's done just knock away the retaining wall allow the canal to flood in bringing with it most if not all the sand under the bow. Cheap and simple it may work it may not but I would have given it a go.
