For hydrology, a tributary is a body of water that flows into a major river, and not into the sea.
Affluent is a word that derives from the Latin word affluens and that describes a thing that flows . In this regard, it must be said that the verb flow is used to mention that which occurs abundantly or in great quantity in a certain place and everything that is directed towards a single point.
The concept of tributary is common in hydrology in reference to the body of water whose mouth does not occur in the sea , but rather in a higher or more important river . The tributary or tributary joins the effluent at the site or area known as a confluence .
Tributaries and effluents
Typically, the difference between tributary and effluent is established by the importance of each river according to its length, flow or basin area. In this way, the river considered most outstanding is the effluent, and the one that contributes water to the other river constitutes the tributary.
Take the case of the Amazon River , which, at 6,800 kilometers , is the longest and largest in the world. Its river system has more than 1,000 tributaries , with about 25 rivers that are more than 1,000 kilometers long . The Amazon rises from the confluence of the Marañón and Ucayali rivers , in northern Peru .
The Nile River used to be mentioned as the longest in the world until recent studies left that privilege to the Amazon. The Nile , in any case, continues to be one of the most relevant rivers for hydrography , with multiple tributaries such as the White Nile or the Blue Nile .
A migration flow occurs when many people from another country enter a nation in a given period.
Symbolic uses of the notion
The notion of tributary can also be used figuratively . For example: “Socialism and anarcho-syndicalism were the main tributaries of this movement that emerged in the most humble areas of North American cities,” “The migratory flow does not stop despite the efforts of the authorities to close the borders.”
In the concept of migratory affluent , in this framework, the term in question reveals a large flow of people , potentially from different nations, who enter a country at a certain moment in history. The last two decades have seen a large increase in this phenomenon, with the main target being the European continent. The most chosen countries in the search to improve the quality of life and escape from inevitable poverty are England , Italy and Spain .
Causes of the migratory tributary
The reason for these choices is rooted in a linguistic issue. On the one hand, there are Latin American emigrants, who usually go to Spain to avoid learning a foreign language ; However, many are unaware of the countless differences that exist in the use of Spanish, although in no way do they represent a challenge that is impossible to overcome. Italy is another of their favorite destinations, given that they rely on the false idea that both languages are practically identical, but also because many of these citizens have Italian ancestry and can obtain the relevant passport, which considerably minimizes the inconveniences and the number of procedures to be carried out.
Finally, there is England , which has the language considered universal, and which is relatively easy to enter, as long as you have a European passport. Many of the people who travel to this country to escape poverty do so because the United States is a much more complicated target to reach, given the difficulty of obtaining a visa. With respect to other countries, such as Sweden , its migratory affluent is not at all negligible, but it does present different characteristics; The change of life that comes with going from a warm climate to an almost eternal winter is very violent, and if we add the urgent need to learn a language, the decision becomes very delicate.
