The first attempt: Karlsgraben or the Fossa Carolina<\/h2>\n
In around the year 793, Charlemagne (Charles the Great), King of the Franks and later Holy Roman Emperor, had an approximately 3km long channel dug starting at the village that today is named Graben near Treuchtlingen across the watershed divide, which separates the north and the south at some 419m above sea level. He wanted to create a route for merchants who transported their goods from the Rhine River along the Main River and further via the Swabian Rezat River to the town of Weissenburg. Via this channel, shipping would have been extended to the Altm\u00fchl River and the Danube River.
\nHowever, due to insurmountable technical reasons this work was never completed. In the early Middle Ages other attempts were made at the creation of the waterway, but they did not come to pass. Traces of this work remain evident even today in the form an approximately 800m long flooded \u201ctrench\u201d and mounds of dug up earth, which are testimony to the grandeur of the project. A very interesting structure in this location is a well with a pump, built precisely on the boundary of the watersheds \u2013 a stream from the well flows \u201cinto two seas\u201d.<\/p>\n\n\t\t

The second attempt: One thousand years later<\/h2>\n
The second \u201cattempt\u201d was successful and resulted in the Ludwig-Danube-Main Canal, connecting the city of Bamberg am Main, through Nuremberg, with Kelheim on the Danube. The canal was built by the Bavarian King Ludwig I in 1836 \u2013 1846. The canal was 172.4km long. 100 locks were built in order to overcome the 417m-above-sea-level watershed divide \u2013 187m \u201cup\u201d from Bamberg and 79m \u201cdown\u201d to the Danube. The locks enabled the passage of boats that were up to 34m long and 4.5m wide. With a maximum draught of 0.7m, boats were able to carry up to 120 tonnes of cargo. The barges were pulled by horses walking along a towpath.
\nThe first years of the canal\u2019s operation were very successful. Approximately 200,000 tonnes of goods were transported to several ports, the largest one in Nuremberg. However, competing railway and road transport began to assert themselves and by 1940 water transport had decreased significantly. That is why in 1950 operations were terminated and the canal was abandoned.
\nWhat does Ludwig\u2019s Canal look like today? Its midsection has been partially preserved. The body of the canal between Nuremberg and Bamberg was used to build a motorway. The canal was destroyed in the Altm\u00fchl River valley as a result of the canalisation of the river in order to make it navigable. Even preserved sections are often interrupted by road embankments and the locks are extensively damaged, overgrown and, of course, without gates. However, the canal is still filled with water and in many villages it constitutes a \u201cromantic\u201d nook. In spite of this, and for these reasons, this waterway is worth exploring.<\/p>\n\n\t\t

The third attempt: Today\u2019s canal<\/h2>\n
Today, there is the Main\u2013Danube Canal, which was put into full operation in September 1992. Plans to replace \u201cLudwig\u2019s Canal\u201d with a larger one were first made in 1917. However, construction only began in 1960 and lasted 32 years, mainly thanks to \u201cenvironmental\u201d problems in the Altm\u00fchl River valley.
\nThe technical parameters of the canal: The total length of the canal is 171km. The channel is a Waterway Class Vb. That means that all shipping facilities are built for ships and ships in tandem that are up to 190m long and 11.5m wide, with a draught of up to 2.7m. The altitude difference when traversing the watershed divide (406m) is overcome via 16 advanced locks. Most have an approximately 25m lifting height and some are designed to conserve water. The canal is also employed for water management. Water from the water-rich Danube basin is used for the operation of the locks and is released into the Main basin, which has less water. Several water reservoirs were specially built for this water management.
\nCurrently, approximately 7 million tonnes of cargo \u201cpass through\u201d this canal yearly and it represents a very important water transport artery between northern and southern Europe. Nuremberg has become a major inland port.<\/p>\n\n\t\t

English historical canal highlights<\/h1>\nThe longest canal tunnel<\/h2>\n
In 1794 a building of Huddersfield Narrow Canal across a highland part of The Pennines, Northern England, between Leeds and Manchester was begun. Its track included a realisation of a courageous project of Standedge Tunnel on the highest part of the canal. This demanding task took 17 years and in 1811 the work was finally put into operation. The tunnel was 5029 m. long, its profile was economy-sized without a paralell track. It stayed in service until 1921 when railway its main competitor \u2013 railway \u2013 took over its function and the water way started to \u201evanish\u201c. Its new era began with a boom of touring by water. In 2001 after ten years of demanding reconstruction the tunnel and the 20 miles long canal with 74 locks, stretching from Huddersfield to Aston, was reopened. While 200 years ago this work was a technical wonder, nowadays its re-opening for a leisure navigation is also a miracle.
\nA canal head-pond itself, that \u201eholds\u201c the tunnel, is also a record holder… This part of the canal is the most highly situated navigable water way in Britain: the canal water level is 197 m. above the sea level. The Picture show both port\u00e1le of the tunnel, a scenery of The Peninnes above the tunnel and a way of \u201epushing\u201c engineless vessels through the tunnel \u2013 \u201elegging\u201c.<\/p>\n\n\t\t

A most interesting boat lift<\/h1>\n
Since 1810 there are two five-locks stairs in service, that enable vessels to get over a sharp terrain breakage, situated at Foton in a Leicester part of The Grand Union Canal. In 1900,to enlarge its traffic capacity, this set comlpeted with a unique boat-lift Foton Inclined Plane, that allowed boats to tackle 22 m high slope of the water way in space of 12 minutes. The boat lift was in service for only 11 years, then it was put out of service for technical reasons and in 1928 a technological part was dismantled and scrapped and the leftover construction started to deteriorate rapidly.
\nThe boat lift was constructed as a double slope one with a transversal motion of two well-balanced water-trough with a utility size of 24,4 m. x 4.6 m for transporting ships up to 70 t. The lift was in its times a state of art and inspired for example a boat lift in Arzwiller, France on Marna \u2013 Rhone canal from 1960.

\nThat is all about its past, but its presence and future are of the same interest:
\nRevitalisation of the whole locality \u2013 locks and a ruin of the boat lift \u2013 was taken over by Foton Inclined Plane Trust. First of all they perfectly renovated the lock stairs, cultivated its neighbourhood including a house for a janitor, installed a small museum in a former water-pamping station and provided access for public by building a new road and parking place. The greatest place concerne the lock itself. Up to now its \u201edeclined\u201c surface with a leftover railtrack, and a water part of a lower roadstead and an upper head race were totally reconstructed. This respectable work, showing great attitude to technical sights, is not close to its end at all: there are plans for rebuilding of the lift itself and puting it into operation \u2013 if the financial situation allows.<\/p>\n\n\t\t

The largest lock cascade<\/h1>\n
Until 1807 the Worchester and Birmingham Canal was constructed only from Birmingham to Tardebigge Warf \u2013 it was led slope contour line and without locks… For its extension to Worchester to the Riv. Sever it was neccesery to get over a \u201every steep incline\u201c of 70 m. in 3 km. This was enabled by building 30 locks that form the longest lock cascade in Britain \u2013 Tardebigge Flight. A structural part of the cascade is also a Tardebigge Engine House \u2013 a water filling station, that provides the whole system and a house of its janitor with water from a close-by water reservoir. Another matter of interest is that in 1807, for about only 8 years, there was one of the very first boat lifts in service \u2013 instead of the upper and the higher locks. There is only few faded signes of its existence left in terrain.
\nAnd now count with me: for passing one lock \u2013 without waiting time \u2013 about 10 \u2013 15 minuts is needed, that means navigating through the whole syst\u00e9m takes 360 minutes, In space of 6 hours you can move 70 m higher (or lower) and 3 km further while working \u201epretty hard\u201c on hand operated locks.<\/p>\n\n\t\t

The biggest swing aqueduct<\/h1>\n
In Barton, Northern England the Bridgewater Canal used to cross Irwell Riv. on a stone canal bridge built in 1761 by the legendary builder Brindley. To make Riv. Irwell navigable all the way to Manchester for a river-marine transport (known as The Manchester Ship Canal), the old bridge was taken down and in 1894 replaced with a the Barton Swing Aqueduct.
\nIt is an unique bulit structure that enables crossing of two waterways of different categories on two different high levels. The steel construction of a canal bridge can \u2013 if needed \u2013 rotate around its axis by 90 degrees and make way for ships on the lower water way. The bridge turns filled up with water \u2013 about 800 t. (plus 1500 t. of its weight) \u2013 after both ends of the canal get closed with waterproof gates. The bridge is 100m long and forms a water bed 5.8m side and 1.8m deep. As well bystanding road bridge can swing \u2013 that is also controlled from control center of the aqueduct.<\/p>\n\n\t\t

Swedish Tourist Canals<\/h1>\n
For motor-yachting and canalboating Sweden can offer not only the outstanding G\u00f6ta Canal (see Travels) but also other water ways surrounded by a marvellous scenery, providing good navigational condition and also a more than sufficient number of harbours and anchorages.

The canal itself equiped with 15 locks overcomes 53 m dH and is set out for ships 24 x 4,5 x 1,5 m with headway of 3 m. The highlight is a lock stairway by Hoventorp.

Smaller sea vessels can get from seaports deep to inland through canals and fairwayed rivers. An important Belgian project was to enlarge the Canal Du Centre. Between towns Charleroi and Mons where the canal gets over nearly 75 m height difference on a short distance, there were four original 100 years old double piston ship lifts replaced with one unique lift. The lift was set into service at the end of 2000 in Str\u00e9py. This generously concepted lift is a \u201eWorld recordman\u201c in a category of double vertical lifts with a counterweight.
