5 Rivers That Flow BACKWARDS – And Still Reach Their Sea

Five rivers flow backwards and still reach their sea, because changing forces redefine their gradient – so what decides their direction? In Chicago in 1900, a 45-kilometer canal turned the river from Lake Michigan to the Mississippi, on the Tonle Sap the Mekong pushes the water 120 kilometers into the lake, and at Saint John the tide of the Bay of Fundy, up to 16 meters, reverses the current twice a day. The Casiquiare also connects two river basins, while the Amazon changed its direction because of mountains – which force is stronger than the river?
