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 Suez Canal is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea and the Red Sea. Opened November 17, 1869 after 10 years of construction, it allows ships to travel between Europe and South Asia without navigating around Africa thereby reducing the sea voyage distance between Europe and India by about 7,000 kilometres (4,300 mi). The northern terminus is Port Said; the southern terminus is Port Tewfik at the city of Suez. Ismailia is on its west bank, 3 km (1.9 mi) from the half-way point. In 2012, 17,225 vessels traversed the canal (47 per day). When built, the canal was 164 km (102 mi) long and 8 m (26 ft) deep. After several enlargements, it is 193.30 km (120.11 mi) long, 24 m (79 ft) deep and 205 metres (673 ft) wide. It consists of the northern access cha...
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.
Watch the short animation to find out how it works. In larger systems thousands of connected devices talk to each other using Internet of Things (IoT) technology. Not only are water losses largely eliminated but water is distributed equitably to all users and delivery flexibility and reliability is improved. A flexible and reliable supply service is needed for farmers to better meet the needs of their crops and make more efficient use of water at the farm level.

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
