Channel support
As a sewer or only attitude of the portion of a navigable channel between - two adjacent channel stages (- usually locks or ship lifts hereinafter). This also includes the highest section of a canal, it is known as the apex posture.
The canal support is usually fed from the upstream lock and releases water to the downstream lock. Within a section, water can also be supplied to the sewer - the top section is always supplied - from outside, and it can also give off excess water there.
The apex of the Canal du Midi in southern France receives its water via the Rigole de la plaine canal from the Bassin de Saint-Ferréol , a reservoir created for this purpose in the second half of the 18th century. Since the canal loses water in its course through seepage, evaporation and sale, water is supplied to it again several times if necessary. This is the case, for example, with Carcassonne vom Fresquel and Trèbes von der Aude . As with the Elbe Lateral Canal , the water supply can also be provided by pumping stations.
Drains are no less important, as the water level of the canal can rise rapidly due to the weather. The unique combination of a canal bridge with a static overflow is with the Aqueduc des Voûtes on the Canal du Midi near Renneville . There, in the event of high tide, water can flow from the canal into the crossed Hers-Mort from the position between the Gardouche and Renneville locks .
