The Montech water slope is a type of canal inclined plane built on the Canal de Garonne, in the commune of Montech, Tarn-et-Garonne, South West France. It is managed by the publicly owned Voies navigables de France and it replaced a group of five successive locks. ==Operating Principles== The principle of the water slope is based on a sloping channel up or down which a wedge of water retained by a water tight gate is moved. This technique was invented in the 19th century by the German engineer Julius Greve and described by the French engineer Jean Aubert in 1961. The Montech water slope was inaugurated in July 1974. A sloping concrete channel is continuously fed by a small stream of water. A movable gate spans the channel. The points of contact of the gate with the channel are tight but not fixed. Two adapted diesel locomotives, one on either side of the channel support the gate. To allow a boat to ascend: the gate is lifted, the boat enters the channel, and then the gate is lowered. This isolates the wedge of water, on which the boat is floating, from the canal it has left. The locomotives ascend the slope pushing the water wedge in front of the movable gate. The boat rides on the water wedge.
