Rivers merging but not blending colors

Due to velocity, water volume, and temperature, many rivers in the US, Switzerland, India, Germany despite merging from multiple streams, maintain distinct colors.

Rhone and Arve Rivers, Geneva, Switzerland

Gia Lang and Yangtze Rivers in Trung Khanh, China

On the left bank of Trung Khanh city lies the Gia Lang River, stretching 119 km, carrying abundant silt, resulting in reddish-brown water. The turquoise river on the right bank of the city is the Yangtze River. By merging with Gia Lang, the Yangtze River gains a stronger water flow to serve the distant Tam Hiep Dam.

Green and Colorado Rivers, Utah, USA

The Green River originates from the Rocky Mountains of Sublette County, Wyoming. After meandering around northern Utah, it flows into eastern Colorado before looping back into southern Utah and converging with the Colorado River at Canyonlands National Park. Despite the narrow canyons here, these two rivers maintain their original colors without blending when they merge.

Ohio and Mississippi Rivers, Illinois, USA

The Ohio River is formed from Pittsburgh, Pennsylvania and after flowing through many states to the southwest, it converges with the Mississippi River at the junction near Cairo, Illinois. Despite merging, these rivers retain their respective colors, and the green-brown divide extends all the way to the Gulf of Mexico.

Alaknanda and Bhagirathi Rivers, Devprayag, India

The Alaknanda River results from the confluence of two glacial rivers, Satopanth and Bhagirath Kharak in Uttarakhand. The Bhagirathi River is formed by the Gangotri and Khatling glaciers under the majestic Himalayas. These turquoise-white rivers converge to form two of the five major branches composing the Ganges River but have never blended in color.

Ilz, Danube, and Inn Rivers merge at Passau, Germany

Passau city carries within itself the convergence of three rivers, the Ilz River, the Danube River, and the Inn River, creating a fascinating blend of colors. While the Ilz River resembles the deep blue of the ocean on a smaller scale, the Inn River, originating from Salzburg, boasts a massive water flow. As it meets a portion of the Danube and Ilz Rivers in Passau, this amalgamation earns the name Danube River, presenting a trio of hues.

The Drava and Danube Rivers, Osijek, Croatia

The colossal Danube River stretches through Croatia, adorned with a russet hue due to its rich sediment, merging with the verdant Drava River originating from the Alps in Italy. Despite some color fading where the Drava meets the Danube, both rivers maintain distinct hues on their respective banks.

The Moselle and Rhine Rivers, Koblenz, Germany

Koblenz, aptly named 'confluence' in German, hosts a river confluence featuring two distinct hues. The Rhine River, Europe's 12th largest river, originates from the Swiss Alps and traverses multiple European countries. The Moselle River, with its greenish tint, originates from France, passes through Luxembourg, and converges with the Rhine at Koblenz.

The Rio Negro and Rio Solimoes Rivers, Manaus, Brazil

Rio Negro appears almost black as it merges with the muddy Rio Solimoes, extending up to 6 km without blending colors. This phenomenon is attributed to differences in temperature, flow rate, and river volume. Specifically, the Negro flows at a rate of 2 km/h at 28°C, while the Solimoes flows at 6 km/h at 22°C.

The Thompson and Fraser Rivers, Lytton, Canada

After traversing British Columbia, the Thompson River, with its deep green hue, nearly concludes its journey at Lytton before joining forces with Canada's longest and sediment-laden river, the Fraser. Despite merging with the muddy river, the Thompson maintains its vivid green color without any dilution.
