Large Wave Flume

The Large Wave Flume is the largest of its kind in North America. Because of its size and ability to operate in high Reynolds regimes, the flume is ideally suited for

  • Cross-shore sediment suspension and transport
  • Wave forces on offshore and coastal structures
  • Nearshore hydrodynamics, wave breaking, swash dynamics, and undertow
  • Tsunami inundation and overland flow
  • Tsunami structure impact, debris and scour
  • Pollutant mixing and transport
  • Scour, pipeline stability and outfalls
  • Liquefaction, cohesive sediments
  • Wave runup, reflection, and overtopping
  • Ocean wave energy systems
