- Ancient Sumerians invented a water channel 4,000 years ago to cope with drought and save their civilization from collapse.
- Archaeologists from the British Museum discovered the structure in the ruined city of Girsu in Iraq and identified it as a flume bridge that accelerated water flow and propelled it to distant locations.
- The flume bridge used the Venturi effect, a phenomenon that was not theorized until the 18th century, and had features that increased its efficiency, such as inclined walls and a sharp drop.
- The flume bridge is unique in history and shows the Sumerians’ advanced knowledge of hydraulics and engineering. It was built as a last attempt to prevent the canals from drying up and the city from being abandoned.
