A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.
Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process, but it also presents challenges to managing urban growth.
A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis. In terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai.
There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.
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:

https://www.europeanwaterways.com - A Tour of Carcassonne in France -The Most Complete Medieval Fortified City in Existence Our Classic Canal du Midi cruises include a tour of Carcassonne. Dating back to the Gallo Roman era, Carcassonne is the most complete medieval fortified city in existence. With its 52 watchtowers, portcullis and extraordinary repertoire of defences, it resisted the many armies that tried to storm this Camelot setting. Carcassonne is a medieval fortified city set atop a hill overlooking the Aude River. Rising against the backdrop of the Pyrénée Mountains, the city is striking not only during the day but also at night, when it is floodlit. Composed of a circle of towers and battlements, turrets and ramparts, with the longest city wall in Europe, Carcassonne is a pe...

http://www.europeanwaterways.com/ - Canal du Midi Cruises From European Waterways - If you are looking to experience the best of the French countryside, a cruise on a Canal du Midi barge might be just the thing for you! The 300 year old Canal du Midi skirts the sun-drenched shores of the Mediterranean before meandering inland through ancient villages, Roman fortifications and famed vineyards. This canal is defined by its beauty, lined with plane trees and crossed by pretty arched bridges.

This is the perfect place for cycling or walking along scenic tow paths, or simply watching the scenery pass by as you relax on the deck of a Canal du Midi b...
Wichtige Information seit Dezember 2015: Es gibt Störungen beim Abspielen des Videos, da eine Plattenfirma namens Ingroove behauptet, dass ich ihre Hintergrundmusik benutze. Dies ist nicht wahr, aber Youtube interessiert das offensichtlich nicht. Diese Plattenfirma erhält alle Einnahmen dieses Videos und bleibt standhaft mit der Meinung, dass ich ihre Hintergrundmusik nutzen würde (das erkennt man auch an der Information Musik von Pure Bliss). Nun, mir wurde gesagt, dass ich zum 4.Mal Einspruch erheben kann, aber das Risiko gegeben ist, dass mein Youtube-Kanal gelöscht wird. Unterstütze den Autor! Diese CD ist ab 6,50€ erhältlich, unter: http://www.jeomra-shop.de Lieber Hörer, auf dieser CD findest du neben der Einleitung drei weitere Titel. Der erste Titel hat das Ziel, körperliche S...
