Wave tank

Welcome to our wave tank demonstration page!

The JBA Trust wave tank shows the impact of coastal defences on flood risk.

In this 12 minute video, Daniel Rodger from Jeremy Benn Pacific uses the wave tank to demonstrate the effectiveness of different types and combinations of coastal defences on the potential for overtopping and flood risk.

The demonstration measures the rates of overtopping for the following defences and conditions:

  • beach during a storm surge
  • vertical and recurved sea walls (with and without a beach)
  • stepped and sloped revetments
  • rock armour
  • submerged near-shore breakwater

The wave tank is one of many physical models that we use to support our education and training activities.
