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.
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.
A true canal is a channel that cuts across a drainage divide, making a navigable channel connecting two different drainage basins.
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.
Both navigations and canals use engineered structures to improve navigation:
The Panamá Canal (Spanish: Canal de Panamá) is a 48-mile (77 km) ship canal in Panama that connects the Atlantic Ocean (via the Caribbean Sea) to the Pacific Ocean. The canal cuts across the Isthmus of Panama and is a key conduit for international maritime trade. There are locks at each end to lift ships up to Gatun Lake, an artificial lake created to reduce the amount of excavation work required for the canal, 26 metres (85 ft) above sea level. The current locks are 33.5 metres (110 ft) wide. A third, wider lane of locks is currently under construction and is due to open in 2016.
France began work on the canal in 1881, but had to stop because of engineering problems and high mortality due to disease. The United States took over the project in 1904, and took a decade to complete the canal, which was officially opened on August 15, 1914. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduced the time for ships to travel between the Atlantic and Pacific Oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan. The shorter, faster, and safer route to the U.S. West Coast and to nations in and around the Pacific Ocean allowed those places to become more integrated with the world economy.

The Celebrity Infinity was making its way from the Pacific Ocean to the Atlantic Ocean through the Panama Canal. This video was taken from a fixed position on the top deck of the cruise ship for more than 10 hours. It shows the whole route and operations with short explanations. The length of the video was reduced to less than 6 minutes. El crucero 'Celebrity Infinity" estaba cruzando el Canal de Panama desde el Océano Pacífico al Océano Atlántico. Este video fue tomado desde una posición fija en la cubierta alto del crucero durante más de 10 horas. Muestra la ruta entera y operaciones con explicaciones breves. La duración del vídeo se redujo a menos de 6 minutos.

My Friends Tigger and Pooh Theme Song
My Friends Tigger and Pooh
Were always there for each other
Youll see just how fun it can be
With so much in the world to discover
And if I need help on the way
Buster might save the day
Or Piglet, Lumpy or Roo
Eeyore has a paw to lend
Rabbit has an ear to bend
Now all were missing is you
Hooray its a honey-ful day
So lets laugh and lets play here together
With My Friends Tigger and Pooh
