The term channel is one that is used to designate those narrow water pipes through which you can navigate or that can serve to redirect the course of water from other natural spaces such as the sea or a river. The channels are always artificial, which means that they are created by man from the rules of hydrology or engineering to facilitate the two objectives mentioned above. There are very different types of canals all over the planet, some better known than others, but all ultimately tend to have a common goal: to make a space an easier place for a certain community to inhabit. The canals can be understood in this sense, as one of the great creations of human beings to adapt to the habitat in which they live.
The channels are narrow water conduits that seek to redirect the watercourse to other areas and also seek to keep that watercourse more controlled to facilitate navigation. While some canals control or direct existing water courses, other canals make the water follow its course through spaces where there was no water before, by digging furrows and opening physical spaces for the water to divert its path. natural course.
The channels can involve a more or less complex engineering work depending on each case, as well as the community that performs them, the objective that takes them forward, etc. Thus, a canal can be simply a furrow of excavated earth while in other cases we speak of really important and magnificent constructions that can last for centuries, just as many of the aqueducts built by the Romans during the Roman Empire remain today. Another characteristic of canals is that, unlike what happens with natural water courses, they maintain a balanced level and the waters tend to show a controlled behavior as they are "trapped" between walls or specially constructed walls. This is what makes navigation easy. Along the canal, several diversions or channeling of the water can be made as dams that seek to stop the movement of the waters.
