The JBA Trust's wave tank shows the impact of different types of coastal defences on the rate of overtopping and resulting coastal flooding. This recurve wall redirects the wave back out to sea, preventing any overtopping. For further details, please see https://www.jbatrust.org/how-we-help/physical-models/wave-tank/.
