In geography, the term “confluence” refers to the meeting place of two or more bodies of water. This may be where a tributary flows into a main river, or where two rivers meet to form a river with an entirely different name. This post presents a dozen confluences of rivers and other bodies of water from around the world, selected from photographs that best show the contrast between the two bodies of water.
1. Confluence of the Rhone and Arve rivers in Geneva, Switzerland. The river on the left is the Rhône, which comes out of Lake Leman. The river on the right is the Arve, which is fed by many glaciers in the Chamonix valley and then flows northwest to join the Rhone on the west side of Geneva, where it is more high level the sludge content creates such a contrast.

2. The confluence of the Ilz and Inn rivers in Passau, Germany. The Ilz is a relatively small mountain stream with blue water, and the Inn is a fairly large river flowing from Salzburg (above). The Inn River has more water flow than the Danube, and yet a stream flows out of the city, which is called in one word - the Danube. This photo was taken from the Oberhaus Fortress above the city of Passau in Lower Bavaria, Germany. The city is also called the "City of Three Rivers". (b k on Flickr)
3. Confluence of the Ohio and Mississippi Rivers in Cairo, Illinois, USA. The Ohio River becomes a tributary of the Mississippi River south of Cairo, Illinois, a small city on a strip of land where the rivers meet (center). The brown, sediment-laden waters flowing northeast from the Ohio River are very different from the green, relatively clear waters of the Mississippi River (flowing northwest to south). The colors of the rivers in this photo are different from the usually green Ohio and brown Mississippi. This suggests that heavy rain in December 2005 in these areas resulted in higher than normal levels of sediment in the rivers. The waters do not mix even 5-6 km downstream. (NASA)
4. The confluence of the Jialing and Yangtze rivers in Chongqing, China. The Jialing River on the right stretches for 119 km. In the city of Chongqing it flows into the Yangtze River. Clear waters Jialing meets the brown waters of the Yangtze. Absorbing the waters of Jialing, the Yangtze becomes even more powerful, continuing its path and passing through the Three Gorges.
5. Confluence of the Rio Negro and Solimões rivers near Manaus, Brazil. Rio Negro is a river with dark (almost black) water, and Solimões is a river with sand-colored waters. 6 km of water from two rivers flow side by side. This is one of the most famous attractions in Manaus, Brazil. And all because of the difference in temperature, flow speed and water density in the two rivers. The Rio Negro flows at about 2 km per hour at a temperature of 28°C, and the Solimões flows at 4-6 km per hour at a temperature of 22°C. (Immelman284)
6. Confluence of the Green and Colorado Rivers in national park Canyonlands, Utah, USA. The Green River is a very long stream in the Rocky Mountains. It winds south into Utah, turning east to flow into Colorado, and then turning south again.
7. Confluence of the Thompson and Fraser Rivers in Lytton, British Columbia, Canada. The Thompson River (clean) ends in Lytton, Canada, where it joins the Fraser River (muddy). (Siacob on Flickr)
8. Confluence of the Alaknanda and Bhagirathi rivers in Devaprayag, India. Devaprayag is a city in the Indian state of Uttarakhand. It is one of the five confluences of the Alaknanda River and is where the Ganges River is formed. Alaknanda rises at the confluence and foot of the Satopanth and Bhagirath Kharak glaciers. The waters of the Bhagirathi River are formed at the foot of the Gangotri glacier.
9. Confluence of the Moselle and Rhine rivers in Koblenz, Germany. At Koblenz the Moselle River flows into the Rhine. The name Koblenz itself means “Confluence”. (PETER JANSEN @ Panoramio.com)
10. The confluence of the Drava and Danube rivers near the city of Osijek, Croatia. On the right bank of the Drava River, 25 km upstream from the confluence with the Danube lies the town of Osijek. (WWF: Amazon of Europe)
11. The confluence of one of the tributaries into the Uruguay River in the Argentine province of Misiones.
In the southeast of France, at the confluence of the Rhone and Saone rivers, is the ancient city of Lyon. Back in the 3rd century BC. e. Gallic tribes founded their settlement here, which was called Lugdunum.
In 43 BC. e. the Romans came here. With their arrival, the settlement expanded, wooden and earthen buildings were replaced by stone ones. New houses, aqueducts, roads and baths are being built. Over time, Lugdunum became the capital of Gaul, which ensured its prosperity. Roman buildings in the city have survived to this day. This is an ancient theater, the Amphitheater of the Three Gauls, large baths and four aqueducts. The Museum of Gallo-Roman Civilization houses ancient mosaics.
In 197, the gradual decline of the city began. In the 5th century it became the capital of Gaul. In the Middle Ages, it was often subject to predatory raids. Many wanted to consider the city theirs, including the German Empire and Catholic Church. And this did not contribute to prosperity in any way.
The situation changed only in the 15th century. By decree of the king, fairs were allowed to be held in the city from 1420. Italian bankers and merchants immediately began to come here. They built houses in the Italian style. There was little space, so the streets were very narrow and winding.
To make it easier to get from one street to another, so-called traboules were built - corridors that pierced through some buildings. This is a unique invention. Traboules were in the form of straight corridors, spiral and ordinary stairs. Now many of them are privately owned and closed to the public, but there are some that you can walk through at certain times.
Like any other ancient city, Lyon has Old city. It is located at the foot of the Fourvière hill, at the top of which is the Basilica of Notre-Dame de Fourvière. It was built in 1872-1896. From here you have a magnificent view of the city. There is another attraction at the top of the hill - a metal tower, which is a copy of the third tier of the Eiffel Tower. It was built in 1892-1894 and now “serves” as a television antenna.
The old medieval city of Lyon is one of the largest and most complete areas of the Renaissance. In 2011 it was listed as a UNESCO World Heritage Site.
The Saint-Jean Cathedral has been preserved since the 12th century. Here is now the residence of the Archbishop of Lyon. There is also an astronomical clock in the cathedral that strikes the time at twelve o'clock in the afternoon.
There is also a medieval hospital, the Hotel-Dieu, in the city. Over its long existence, this complex of buildings was rebuilt many times.
There are many squares in Lyon. Some of them are many years old. Place Bellecour with its chestnut alleys, gardens and the equestrian statue of Louis XIV evokes an indelible impression.
Between the Rhône and Saône rivers is the Presqu'ile peninsula. This is the center of Lyon. Here you will find the City Hall, museums, the Opera, the Celestin Theater, numerous boutiques, bars and restaurants.
Residents of Lyon love holidays. Since the mid-19th century, the Festival of Lights has been held in December. This is the festival of illuminations, when residents place candles on the windows, and thousands of lamps, lights, lanterns and lamps are lit on all the streets. Tourists love to attend this event.
Every summer, in the open air, in the ancient Fourvière theater, built in 15 BC. e., there is a festival of music, theater and cinema called Nuits de Fourvières.

Why is the town sometimes called the beginning of the most sacred river in India - the Ganga?
Do you know this unforgettable story about how, in ancient times, the Ganga was not an earthly river at all?
The story of Ganga and King Bagirati
In ancient times, the Ganga flowed across the sky in the form of the Milky Way, and King Bagirati performed asceticism day and night. And when he, so righteous, asked Ganga to descend to Earth, she indeed descended, but so that under the weight of Ganga the Earth would not move from its axis, the great Shiva nobly offered his head, and Ganga descended to Earth along his strands. Having fallen on the head of the beautiful Shiva, it spread through his sacred long tangled hair, and then gathered together again. Therefore, the god Shiva is depicted with Ganga on his head.
So with this Ganga everything is not as simple as with other rivers. Ganga bears its proud name not from the very source, but from the place where two powerful streams united on Shiva’s head into one. This place is a town .
Devprayag - the confluence of Bagirati and Alaknanda
Among Hindus, the confluence of two rivers is called “prayag” and is considered sacred. There must be a temple in such a place. If there is a city during the merger, then it most often bears the name “...-prayag”, for example, Rudraprayag, Devprayag, Karnaprayag...
At Devprayag, two sacred rivers - Bagirati and Alaknanda - merge to form the most sacred river in India - the Ganga.
The source of Bagirati is the Gomuk ice cave on the Gangotri glacier.
The source of Alaknanda is located near the Neelkanth mountain in the Badrinath region.
Hindus consider the Gomuk ice cave to be the source of the Ganges.
A 19-kilometer trail leads to this ice cave, which I have already walked twice, and I still can’t get enough, I really want to repeat this trek again.
So the great Ganga gets its name only here, in Devprayag.
The moment of the confluence of two rivers. Very impressive!
These rivers differ in color: Alaknanda is dark, Bagirati is light, whitish. After merging, their waters flow for some time without mixing, and a clear boundary is visible, especially when viewed from above.
In the next photo: on the right - Bagirati, on the left - Alaknanda
Bridge over Bagirati
Streets of Devprayag
Rocky coast of Alaknanda
Town very sincere, not at all touristy - in the town itself we could not find a single hotel to spend the night.
But they found a cool hotel a couple of kilometers from Devprayag, on the high bank of the Ganges.
From there we watched with interest how the border of the two rivers moved either to the right bank or to the left, depending on whose peaks the snow was melting the most at the moment. For example, in the evening the water boundary ran along the middle of the channel, and early in the morning we discovered that Bagirati had completely fallen asleep, Alaknanda strangled her, and the boundary moved almost close to the right bank.
I worried about my beloved Bagirati, as if I were a close friend :)
Well, how can you not say that rivers are living beings? Each river has its own character, its own energy, and at the confluence this energy intensifies many times over. The confluence of rivers is a place of Power.
At the confluence there is an ancient temple. They say that it is 10 thousand years old...
And this is the goddess Ganga. Well, isn't she beautiful?
On the arrow itself, in the mornings and evenings, the pujari performs aarti - fire puja. When in the evening, standing right next to the water, it turns its lights to the accompaniment of sacred hymns, and you sit on the steps of the arrow, two powerful streams rushing from both sides of you, you feel like you are part of this great event - the birth of the Ganga.
Road to Devprayag
You can get here by bus from Rishikesh - 70 km towards Badrinath, i.e. upstream. The road stretches along the green slopes above the Ganges, very beautiful. All along the road, serene monkeys sit on the sides of the road, phlegmatically crossing the road right in front of the vehicles. Not far from Devprayag, a large blue Shiva stands near the road.
When you drive along this the most beautiful road from Rishikesh to Devprayag, then for many kilometers you can see that the Ganga in these places is quite calm, despite the high steep banks. One of my dreams that has not yet come true is to cover this section in a kayak...
View of the Ganges from the road 
Six miles from Manaus, Brazil, one can witness one of nature's greatest displays of majesty - the confluence of two colorful rivers, the Rio Negro and Solimões. When meeting, multi-colored waters do not mix, but continue their path side by side, while each river remains with its own color
The waters of the Rio Negro are darker, slower and much heavier than the waters of Solimões. Temperature, density, water speed - all this divides these water flows over 6 kilometers before they form the great Amazon 
When you see the process of meeting waters live, at first you don’t believe your eyes. It's like two completely different horizons meeting each other - the sandy beige waters of one river and the black waters of another, meeting each other but not mixing
This phenomenon is also explained by differences in temperature and flow speed. The Rio Negro flows at a speed of 2 kilometers per hour and a temperature of 28 degrees Celsius, and the Solimoes at a speed of 4 to 6 kilometers and a temperature of 22 degrees Celsius 
The surrounding nature is also impressive - the Amazon rain forests, the lungs of our planet, which have a direct impact on the Earth's atmosphere. These places are famous for their huge diversity of flora and fauna. It is not surprising that this is one of the most popular tourist destinations not only in Brazil, but throughout South America
