We have 100 m of mobile multi-element wavemakers, equipped with active wave absorption to remove reflected wave energy within the basins and flumes, and a further 50 m of long crested random wave paddles. The multi-element paddles are capable of generating a full range of long crested and multidirectional seastates including:
> JONSWAP (defined by wind speed and fetch)
> Pierson Moskowitz
> International Ship Structure Congress (ISSC)
> International Towing Tank Congress (ITTC)
For short crested seas, the spreading function can be defined in a number of different ways. These include cos2θ, cos6θ, cosnθ, Mitsuyasu and exponential functions.
In the wave basin models significant wave heights (Hs) of up to 0.25 m can be generated in water depths of up to 0.8 m. In addition, our wave-current basin can generate uni-or bidirectional current discharges of up to 1.2 m3/s.
