The Rhine-Herne Canal (German: Rhein-Herne-Kanal) is a 45.6 kilometer (28.3 mile) long transportation canal in the Ruhr area of Nordrhein-Westfalen, Germany, with five canal locks. The canal was built over a period of eight years (5 April 1906 - 14 July 1914) and connects the harbour in Duisburg on the Rhine with the Dortmund-Ems Canal, following the valley of the Emscher. It was widened in the 1980s. The Rhein-Herne canal ship was designed specifically for this canal; normally of about 1300-1350 ton capacity, it has a maximum draft of 2.50 meters, a length of approximately 80 meters, and maximum beam of 9.50 meters.
Originally the Rhine-Herne channel ended in Herne, where it met the transportation canal running from Henrichenburg to Herne, the intersection situated just above the East Herne lock. After the closure of the last part of the Henrichenburg to Herne canal, i.e. the section from the port at the Friedrich der Große coal mine to Station Street in Herne, the Henrichenburg-Herne section of the Rhine-Herne Canal was also closed. Route A42 of the Federal Motorways now partly follows the route of the disused canal, from the east side of the bridge over Station Street to the bridge over the Landwehrbach in Herne.

[edit] Water System
The distribution of water in the canal is realised through five pump stations. Located at Duisburg-Meiderich, Oberhausen, Gelsenkirchen, Wanne-Eickel and East Herne, they pump water from the Rhine into the canal at each stage. As well as this, water from the Lippe river to the east is brought in through the Datteln-Hamm canal.
[edit] Locks
[edit] Duisburg-Meiderich Lock
In 1980 the current lock was completed, including a 24 metre high under-gate and control platform, which has now become a visible yellow landmark in the Ruhr landscape. The intended harbour of the old lock is today underwater and part of the foundations of the canal walls. This harbour was meant to be a possible spot for the eventual significant reconstruction of the lock, but it was never used for this purpose. Possible future construction of the lock was taken into consideration when the canal was opened in 1914. Instead of the old 165 m long and 10 m wide lock, the new lock has a length of 190 m and a width of 12 m, in order that
the today's air-lock was finished placed to air-lock Duisburg avoiding Erich, whose 24 m high untertor with the control stand a far away visible yellow landmark sets in the port and Ruhr landscape. The outer port of the old air-lock is to be recognized today still in the underwater by the masonry of the channel walls. As reserve place for a possibly necessary new building of the air-lock it is not filled. The building of predecessors of the today's air-lock was taken with the channel opening 1914 in enterprise. In place of the old 165 m are enough and 10 m broad air-lock has the new chamber of a lock a usable length of 190 m and for width of 12 m, so that also large thrust federations with lighters of the European class II can pass the air-lock. The stroke depends on the Rhine water level. With appropriate flood of the Rhine the water level can be even higher rheinwaerts than in the channel, so that into the channel to mountain, but to valley must be channeled not as usual. The air-lock does not have an own pumping plant, but the pumps in the harbor basin C of the Ruhrorter of port provide for back pumps of the water into the channel. The air-lock can be served by a person. Here at the beginning of the channel is the collection point for the use fees, which become retract and extending ships registered. About 25000 ships with altogether 15 million tons of freight happened to 1996 avoid Erich ago the air-lock.

port Grimberg, in the background pit William of the bill Pluto in HerneDer port Grimberg is because of the southern channel bank in gel churches, close of the city boundary to Herne. It was designated after the close lock Grimberg, from which today only admits the foundation walls are. It predominantly served for the landing of ore for the supply of the iron and steel plants in Bochum and gel churches. Here the ore course (Bochum) began. With the quiet putting of the metallurgical plants it lost its original function. Today it serves building material and recycling enterprises for the treatment and shipment of their products.

former air-lock Herne west the former air-lock Herne west was replaced with the renewal of the lock installation Herne east with. In addition the channel in the section became Herne west - Herne east around 4,5 m deepens. The old air-lock was not sufficient for the modern ships and thrust federations in length and width any longer. The built volumes were obsolete and damaged by mountain lowerings substantially. In the course of the distance of the air-locks the outside walls of both chambers of a lock were received. In particular at the southern wall the measures are to be recognized for the reconciliation of the mountain lowerings still clearly. The chamber wall had to be increased at the western end by 80 cm, at the eastern end however by 3,5 m. This is to be recognized in the panorama picture by the difference between brickwork and reinforced concrete increase. This air-lock stands on the sec. and US jump. When planning of the channel was well-known, one went out however of the fact that straight mountain lowerings would not take place here, since within the jump range (and air-lock safety columns) no hard coal should be diminished.

air-lock Herne east the lock installation Herne east became in the years 1986 - 1992 renews. The new chambers of a lock are in each case 190m long and 12m broad. The Drempeltiefe (depth of water at the upper gate) amounts to 4m. to the upper water forms a turning segment gate the conclusion. Stemmtore lock the chamber to the underwater. The difference between upper and underwater amounts to 12,8m. An air-lock course needs approx.. 14 minutes - retracting and driving out extending of the ships not counted. The two chambers of a lock are so connected that the water running off can be used chamber for filling up the others, until resembling and occurred. The second half water in the underwater is discharged, the other one, half-full chamber is then filled from the upper water. The water consumption for each air-lock course is in this way halved. Since a channel is a standing waters and no river, the loss of water of the upper water must become when channeling complex by Zurueckpumpen again balanced. To the pictures in the gallery: The left picture shows the lock installation from the underwater, the outer port, which is used by waiting ships, the lock installation with the two lower gates and the control stand, which resemble a Flughafentower. The chambers are constructions from reinforced concrete with a Verklinkerung of the opinion side. The gate of the southern chamber is opened. The driving out motor ship ' Carina ' comes from Decin into Tschechien. The water level difference in the chamber can be measured at the damp alga vegetation of the left chamber wall (12,8m). At the upper contour the bridge of the Horsthauser road over the channel. On the bank right several anglers, who use the fish wealth within the range of the lock installation gladly. The picture of the upper water shows the southern chamber left with the upper gate. The northern chamber (right) is opened to the exit. To open this gate is sunk around one closely above the Drempels lying axle against the upper water. The retracting and extending the ships are regulated over traffic light devices. The schleusenmeister can operate by remote control the entire plant alone, since at all important points television cameras are installed. In the chamber right: Motor ship Aurora before the exit. The third picture shows the chamber opened to the upper water after exit of the second ship of the observed air-lock course - motor ship Bydgoszcz from Poland. The right picture shows the channel process to the west, in front the outer port, the road bridge, then a corn mill and their siloanlagen on Recklinghaeuser area, mentioned above, left of it and approx. 5 km removes the hard coal power station of the STEAG in the local part Herne Baukau. Both channel banks are gesaeumt by fastened ways, which are frequently used by Spaziergaengern and cyclists.
