Dutch scientists have created the world's biggest artificial wave in an attempt to help save the low-lying Netherlands from devastating floods.
Engineers in the city of Delft generated waves over 5 meters high, using a 10-meter-high steel wall that pushes the water back and forth in a huge concrete tank. The main purpose of the multi-million-dollar facility is to test the resistance of flood-defense technology, such as dams, dykes and barriers. Scientists say generating such waves is the only way to find out if defenses can be reliable in real-time floods and tsunamis.
