Orinoco is the most important river of Venezuela. It covers a distance of more than 2,500 kilometers to the Atlantic Ocean from its source, which is in the Guiana highlands at the Brazilian border. Orinoco happens to be the eight largest river of the world and the second largest in [url=http://www.best-country.com/south_america]South America[/url] after the Amazon.
Few Venezuelan rivers flow into the Orinoco and increase the volume of water. Among the rivers of Venezuela, Caroni is another important one. The genesis of this river lies in the Guiana highlands, from where it flows towards the north into the Orinoco upstream. The Venezuela rivers are great attractions among the tourists for cruise rides as well as the natural beauty.
Apure River is one of the important Venezuela rivers. It is located in the western side of Venezuela. Apure River of Venezuela is the main tributary of the Orinoco River, which is the most important river of Venezuela. Apure River in Venezuela originates in the Cordillera de Merida and flows northeastwards and eastwards for a distance of about 510 miles, through the middle of the Llanos (the Orinoco plains).
The most important tributaries of Apure River are Portuguesa and the Guarico, which flow from the north. The river protects the environment of Venezuela. Apart from vegetation, the rivers also influence in making the local weather very soothing.
Arauca River is the western tributary of the Orinoco river, which is the most important among the Venezuela Rivers. Originating from the Cordillera Oriental of the Andes Mountains near the Venezuelan-Columbian border, the river flows through Venezuela as well as Columbia. Arauca River in Venezuela covers a stretch of 800 kilometers while flowing through the east. Arauca River also forms a boundary between Venezuela and Columbia.
Arauca River of Venezuela flows almost parallel to the Meta and Apure rivers in Venezuela for 100 kilometers, to join the Orinoco river. Being one of the distinguishable tributaries of the Orinoco river, Arauca River is considered to be a significant river of Venezuela.
Branco River of Venezuela is also known as Rio Branco in Portuguese. Branco River of Venezuela originates just above the Boa Vista at the junction of the Rio Uraricoera, which rises in the Serra Parima on the border of Venezuela, and the Rio Takutu, which flows from the Serra Pakaraima on the border of Guyana. Rio Branco river in Venezuela flows through the south west part of Venezuela and covers a stretch of 775 kilometers prior to joining the Negro river. Branco river is one the significant Venezuela rivers as well as Brazil rivers, as it also flows through Brazil.
The topography of upper Branco is markedly different from the topography of the lower course of the river. The general direction of the river veers from south to southwesterly direction. The upper course of Branco is very ragged as there are a number of rapids that break its course. However, the river takes a more tranquil form in the lower part of its course, making navigation possible. The water level of Branco can vary extensively from the dry season to the wet. The dry season sees the river running at much below its average water level. So much so, that the navigation between Boa Vista and the Negro river becomes extremely difficult during the dry season.
The Cuyuni river is one of the significant rivers in eastern Venezuela and also in northern Guyana. The Cuyuni river is a notable tributary of the river Essequibo and meets it at Bartica. The entire length of the Cuyuni river is 563 kilometers and it serves many valuable purposes.
Utility of Cuyuni River
The Cuyuni river is useful to inhabitants of the country in many ways. According to research it has been proved that the entire region of Cuyuni river is fertile with alluvial gold and the river basin is rich in metallogenic products. Some of the tributaries of Cuyini river bear diamonds and most of the river's length is navigable. The Kamaria Hydroelectric Power project is constructed on the Cuyuni and produces considerable amount of electricity.
Course of Cuyuni River
The source of Cuyuni river is in the Guiana Highlands of Venezuela and it moves through a region of undulating topography before meeting the Mazaruni River. Though it rises in Venezuela, the main course of the river is covered in Guyana. Thus much of the meandering course of Cuyuni river is noticed in the lush tropical rainforests of Guyana.
The Cuyuni river has many beneficial properties and is profitable to both the nations of Venezuela and Guyana in a number of ways.
The Rio Negro Amazon River Venezuela
The Rio Negro Amazon River Venezuela is famous as one of the crucial rivers of the country and the biggest left bank tributary of the river Amazon. The Rio Negro Amazon River Venezuela is one of its kind, being the greatest black water river in the entire world.
Color of Rio Negro
The literal meaning of Rio Negro is 'Black River', but the exact shade is not really black. Compared to the light brown color of the Amazon and Orinoco rivers, Rio Negro is very dark. The river resembles the color of tea to be more precise. The reason behind this color is the presence of tannins or humic acids, which are certain complex organic compounds produced by plants to keep herbivores at bay. Thus it is from the presence of vegetal debris that Rio Negro gets its name.
Origin of Rio Negro Amazon River Venezuela
Rio Negro originates as the Guainia River in eastern Colombia and then flows through the Colombia-Venezuela border. It then changes its direction and flows through Brazil and finally meets the Amazon River at the city of Manaus. The Rio Negro is fed by its primary tributary, the Rio Branco and also has many secondary channels as well as numerous islands.
In 1638 the Rio Negro Amazon River Venezuela was discovered as a significant commercial channel by a Portuguese explorer named Pedro Teixeira.
The Orinoco river Venezuela
The Orinoco river Venezuela is one of the largest Venezuela rivers. It is also considered to be the largest of all river systems in South America. The Orinoco river originates in the southern borders of Venezuela and Brazil and has an expanse of 2,410 kilometers. Its name is in compliance with its characteristics. The word Orinoco is a Guarauno word, which means 'a place to paddle' or a navigable place.
Flowing towards the west, it takes a turn towards the north bordering Columbia. It then flows towards the east and divides Venezuela before merging in the Atlantic. A vast grassy expanse called the llanos stretches towards the north of the Orinoco river. The south western part of the Orinoco river is covered by a vast expanse of tropical forests. The Guiana Highlands, which are also known as the Guyana shields cover the rest of the landscape. Pre-Cambriam rocks, which date back to 2.5 billion years form the Guyana shields. These rocks are the oldest in the continent. The Orinoco river basin has an expanse of 880,000 to 1,200,000 square kilometers.
The riverine forests have the jutting contours of the tepuis or a stone plateaux, among which the most famous are the Roraima and the Auyantepui, which are the custodians of the Angel Falls. With over 200 tributaries, Orinoco River Venezuela also adds up to the economy of Venezuela because of its navigability. The criss crossing Orinoco river course adds to the beauty of the landscape of Venezuela.
