Concept in Definition ABC

The term channel is the one used to designate those conduits of Water narrow ones that can be navigated or that can serve to redirect the course of water from other natural areas such as sea or a River. Channels are always artificial, which means that they are created by man from rules of hydrology or from engineering to facilitate the two objectives mentioned above. There are very different types of channels all over the planet, some better known than others, but all in short. They tend to have a common goal: to make a space an easier place for a certain community to inhabit. The channels can be understood in this sense, as one of the great creations of the human being to adapt to the habitat in which you have to live.

The channels are narrow water conduits that seek to redirect the water course to other areas and also seek to keep that water course more controlled to facilitate navigation. While some canals control or direct existing watercourses, other canals make water flow through spaces in those that previously had no water, from the digging of furrows and the opening of physical spaces for the water to divert its natural course.

Channels can involve more or less complex engineering work depending on each case, as well as the community that performs them, the objective that carries them forward, etc. Thus, a canal can simply be a furrow of earth dug while in other cases we speak of constructions really important and magnificent that can last for centuries, just as many of the aqueducts built by the Romans remain today during the Roman empire. Another characteristic of canals is that, unlike what happens with natural water courses, they maintain a level balanced and the waters usually show a controlled behavior when being "trapped" between walls or walls especially built. This is what makes navigation easy. Throughout the canal, several diversions or channeling of the water can be made as dams that seek to stop the movement of the waters.
