Abstract: Monsin movable dam is located on river Meuse, in Belgium, and allows for navigation between Liège, Maastricht and Anvers. The Walloon administration is considering its renovation since the present dam was built in 1930. Each of the 6 openings is closed by a vertical lift valve on top of which is sat a flap gate. The ratio between the heights of these elements will be slightly modified to ease the regulation. Several hydraulic behaviours had then to be checked. A 1:15 scale physical model of a slice of this dam was built in a 1 mwide flume, according to Froude similarities. It was used to determine (i) the efficiency of the aeration of the overflowing nappe; (ii) the relationship between the discharge and the valve position; (iii) the hydrodynamic pressure distribution on the valves; and (iv) the energy dissipation on the downstream concrete apron.
