Numerous and sometimes utopian projects have been imagined to connect the Atlantic Ocean and the Mediterranean Sea by a canal. Leaders like Augustus, Nero, Charlemagne, Francis I, Charles IX and Henry IV thought about it4:11, because it is a real political and economic issue. Indeed, the construction of such a structure makes it possible to prevent boats (commercial ships but also the king's galleys) and goods from taking to the sea and bypassing the Iberian Peninsula. At this time, maritime transport involved many dangers such as brigandage, pirates and Barbary corsairs7.The most realistic projects were presented to the king in the 16th century. A first project was presented by Nicolas Bachelier in 1539 to the States of Languedoc8, then a second in 1598 by Pierre Reneau3:23, and finally a third project proposed by Bernard Arribat de Béziers in 16179:8. But these projects were abandoned because they were not sufficiently thought out in terms of water supply to the canal and proposed a system of diversion of water from the rivers of the Pyrenees that was too complex or even impossible to implement. In 1650, another engineer also proposed diverting water from the Ariège at Cintegabelle to bring it via a non-navigable canal to Pech-David near Toulouse. But, here too, the question arises of bringing the water to the threshold of Naurouze higher than Toulouse9:9.Projects are therefore not launched for fear of losing too much money and out of conviction of the human impossibility of digging such a canal. However, Pierre-Paul Riquet, a tax collector in Languedoc, proposes a more convincing project than the previous ones. When Louis XIV received his proposal through the archbishop of Toulouse, Mgr. his reign of an imperishable work7. The management of rivers being difficult, only a canal is required between the Atlantic Ocean and the Mediterranean Sea. It is easier to manage the flow of a canal than that of a river to maintain regular traffic throughout the year. The Canal du Midi is a canal with a dividing reach because it must cross a height between two valleys. Indeed, the construction of this canal requires the passage of the Naurouze threshold or the Graissens threshold3:13. Thirty years before work began, the study of a similar project was entrusted to an assembly of which Riquet's father was a member.In 1642, the Briare canal was inaugurated, the first canal with a dividing reach built in France. Its construction was resumed in 1635 by the Boutheroue brothers and Jacques Guyon. Its operation showed the difficulties due to the lack of water at the level of the divide in summer. Hector Boutheroue, a younger brother of the concessionaires of the Briare canal, will act as a hydraulic expert to the States of Languedoc to give his opinion on the projects presented on this canal. Riquet visits the Briare canal at its inauguration. The problem of supply at its highest point, the Naurouze threshold, quickly became a challenge in ensuring the feasibility of the canal. Riquet bought the lordship of Bonrepos around 1652 and then, until 1658, all the water rights of the nearby community of Revel. This allows him to control the water that feeds Revel thanks to the Sor river and a diversion canal. It was his knowledge of the hydrography of the Black Mountain region that he traveled with the Revel fountain man Pierre Campmas that allowed Riquet to find the solution to the problem of water supply to the canal, particularly in summer. , by opening a diversion canal not into the Sor and the Agout but at the threshold of Naurouze by making it pass through the threshold of Graissens3:19-21, 24; 192.HighlightsSign indicating the ocean lock at the threshold of Naurouze, where the reach is highest with 189 m altitude.In 1660, Riquet found the solution to the main problem: the arrival of water at the dividing point in order to supply both sides of the canal. His idea is to recover the water that flows in the Black Mountain. His significant knowledge of the hydrography of the Black Mountain and the Sor allowed him to imagine an ingenious irrigation system3:24,10. He is inspired by the French engineer AdIn 1642, the Briare canal was inaugurated, the first canal with a dividing reach built in France.
