With more extreme flooding occurring because of climate change and rising sea levels, things like wave generators are being constructed in order to test preventative measures like flood dykes and sand dunes. Among the many low-lying countries affected by such flooding is Holland, which has produced the Delta Flume machine, creating the largest man-made waves in the world.
A hydraulic-powered wave board produces waves up to 4.5 meters high, which flow along the 300-meter long trough. At the end of the trough, scientists place various things like a newly designed dyke, gravel beach or sand dune to test their strength and effectiveness in flood prevention. The water trough is designed after realistic land conditions, with a slanted bottom similar to that of a coastline. Effects are measured using laser scanners and sonar machines that are integrated inside of recesses in wave generators' walls.
