Our planet doesn’t cease to surprise us, even when it does something like pictured in these photos. These rivers are for real; they’re not polluted, they are confluences, as in, meetings of two or more bodies of water, be it two rivers or canals.
How on earth could this possibly happen, you ask? Apparently it occurs when two streams join to become one river or, as in the examples below, when a tributary joins a larger river, called the main stem, or when two streams meet to become the source of a river of a new name.
Sure, fine, but what about the fact that the water doesn’t mix? Confluences such as that of the Gombak River (previously known as Sungai Lumpur, which means muddy river) and the Klang River in Malaysia are often clearly defined because of the different debris, vegetation and chemicals that the water carries.
