Canals and navigations are human-made channels for water. In the vernacular both are referred to as 'canals'. The main difference between them is that a navigation parallels a river and shares its drainage basin, while a canal cuts across a drainage divide.
Types of artificial waterways
A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height.
Most commercially important canals of the first half of the 19th-century were a little of each, using rivers in long stretches, and divide crossing canals in others. This is true for many canals still in use.
Structures used in artificial waterways
Both navigations and canals use engineered structures to improve navigation:
Although the Austrian, German and Russian administrations exerted much pressure on the Polish nation (during the 19th and early 20th centuries) following the Partitions of Poland, which resulted in attempts to suppress the Polish language, a rich literature has regardless developed over the centuries and the language currently has the largest number of speakers of the West Slavic group. It is also the second most widely spoken Slavic language, after Russian and just ahead of Ukrainian, which comes third.
"Low" is the debut single by American rapper Flo Rida, featured on his debut studio album Mail on Sunday and also featured on the soundtrack to the 2008 film Step Up 2: The Streets. The song features fellow American rapper T-Pain and was co-written with T-Pain. There is also a remix in which the hook is sung by Flo Rida rather than T-Pain. An official remix was made which features Pitbull and T-Pain. With its catchy, up-tempo and club-oriented Southern hip hop rhythms, the song peaked at the summit of the U.S. Billboard Hot 100.
The song was a massive success worldwide and was the longest running number-one single of 2008 in the United States. With over 6 million digital downloads, it has been certified 7× Platinum by the RIAA, and was the most downloaded single of the 2000s decade, measured by paid digital downloads.

X-Dream are Marcus Christopher Maichel (born May 1968) and Jan Müller (born February 1970); they are also known as Rough and Rush. They are some of the cult hit producers of psychedelic trance music and hail from Hamburg, Germany.
Muller was educated as a sound engineer. Maichel was a musician familiar with techno and reggae, and was already making electronic music in 1986. In 1989 the pair first met when Marcus was having problems with his PC and someone sent Jan to help fix it. That same year they teamed up to work on a session together. Their first work concentrated on a sound similar to techno with some hip hop elements which got some material released on Tunnel Records.
During the early 1990s they were first introduced to the trance scene in Hamburg and decided to switch their music to this genre. From 1993 they began releasing several singles on the Hamburg label Tunnel Records, as X-Dream and under many aliases, such as The Pollinator. Two albums followed on Tunnel Records, Trip To Trancesylvania and We Created Our Own Happiness, which were much closer to the original formula of psychedelic trance, although featuring the unmistakable "trippy" early X-Dream sound.
Radioactive covers many different styles of hip hop fusions, being alternative hip hop as principal musical genre. Hardcore hip hop is represented on the tracks "Radioactive Introduction", "Throw It Up", "Get Away", and "Slumerican Shitizen". A horrorcore rap style is used in "Growin' Up in the Gutter", whereas "Hard White (Up in the Club)" is a crunk party track. "Let's Roll", "Write Your Name", and "Radio" follow a pop rap style, with catchy hooks and beats. "Animal" is a fast-paced hip hop party track with a dubstep influenced beat. "Good Girl" utilizes an R&B-tinged feel, while "The Hardest Love Song in the World" is a g-funk hip hop track. Yelawolf covers a variety of lyrical themes in these album, from gangsta rap lyrics in "Get Away" and "Throw It Up", to more conscious and slightly political tracks such as "Made in the USA", "Slumerican Shitizen", "Write Your Name", and "The Last Song". "Radio" is about the internet taking over how music and music videos are received by fans. It also refers to radio stations playing the same songs constantly and singers being discovered via the internet. The song contains several references to rock and rap artists and their songs from the past. The album's final track, titled "The Last Song" described as very personal about Yelawolf's life, and it's a very emotional final letter to his absent biological father and talks about other past struggles.
