The Canal du Midi is a 240 km (150 mi) long canal in Southern France. Originally named the Canal Royal en Languedoc and renamed by French revolutionaries to Canal du Midi in 1789, the canal is considered one of the greatest construction works of the 17th century.
The Welland Canal is a ship canal in Ontario, Canada, and part of the St. Lawrence Seaway and Great Lakes Waterway. The canal traverses the Niagara Peninsula between Port Weller on Lake Ontario, and Port Colborne on Lake Erie, and was erected because the Niagara River—the only natural waterway connecting the lakes—was unnavigable due to Niagara Falls. The Welland Canal enables ships to ascend and descend the Niagara Escarpment, and has followed four different routes since it opened.

The Agde Round Lock is a canal lock on the Canal du Midi that connects to the Hérault River in Agde France. It is almost unique because it is round, which allows a boat to turn around, and the fact that it has three sets of lock gates, each with a different water level. It was built in 1676 of volcanic stone and was originally 29.20 m in diameter, 5.20 m deep.
The Seuil de Naurouze, or Col de Naurouze, is the highest point of the Canal du Midi in southern France. It is the watershed point identified by Pierre-Paul Riquet when he designed and built the canal. Water falling on the western side of this point flows to the Atlantic Ocean and on the eastern side to the Mediterranean Sea. It is on the border of the department of Haute-Garonne and the department of the Aude.
The balancing of incoming and outgoing water allows the Canal du Midi to operate as it does. Each time a lock operates, large quantities of water are either required to fill it or dump from it into the lower level pound. There must be a constant source of water in order to fill and the excess water dumped must have a place to exit the canal without it overflowing. Being able to provide this water source was one of the most important problems to be solved by Pierre Paul Riquet, its creator.
