Canal

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.

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.

Structures used in artificial waterways

Both navigations and canals use engineered structures to improve navigation:

Adventure

An adventure is an exciting or unusual experience. It may also be a bold, usually risky undertaking, with an uncertain outcome. Adventures may be activities with some potential for physical danger such as exploring, skydiving, mountain climbing, river rafting or participating in extreme sports. The term also broadly refers to any enterprise that is potentially fraught with physical, financial or psychological risk, such as a business venture, a love affair, or other major life undertakings .

Motivation

Adventurous experiences create psychological arousal, which can be interpreted as negative (e.g. fear) or positive (e.g. flow), and which can be detrimental as stated by the Yerkes-Dodson law. For some people, adventure becomes a major pursuit in and of itself. According to adventurer André Malraux, in his La Condition Humaine (1933), "If a man is not ready to risk his life, where is his dignity?". Similarly, Helen Keller stated that "Life is either a daring adventure or nothing."

Canal Walk

Canal Walk is a shopping centre in Cape Town, South Africa, that opened in 2000 and was built around a canal. It has a total retail area of 141,000-square-metre (1,520,000 sq ft). The centre forms the heart of a mixed-use development known as Century City, which includes office blocks, residential areas and the Ratanga Junction theme park.

Canal Walk is the 3rd largest shopping centre in Africa. Gateway Centre in Durban is the largest and the Sandton City complex in Johannesburg is larger when including the Nelson Mandela Square annex. Built in what the developers call "Cape Venetian architecture", the shopping centre hosts over 400 stores, 7,000 parking bays, numerous restaurants, 20 cinemas plus a game arcade.
