About
In the Waterloopkundig Laboratorium De Voorst in Marknesse research is done to the closure of the Volkerak on a scale model of this area, a.o. to the flow velocities and the closure with the closing caisson. The twelve culvert caissons are waiting to be sunk in the construction pit at the Volkerak.
Human-made No record of this work says a model made it. What this means.
