River waters simply meeting is one thing, but when those bodies of water display distinguishing colors from one other without mixing, it can create some unusual environmental displays.
When two or more bodies of water meet, like rivers, it’s called a confluence, known also as a conflux. This occurs when two streams join to become one river.
As you can see in these pictures, confluences take place all over Russia. This results in some fascinating scenery. These color differences are determined by what debris, silt, vegetation or chemicals the water caries, which clearly contrast the river they join into.
