The concept of floating vegetation-based islands for bioremediation of aquatic ecosystems is well known. Less well known are their hydrodynamic capabilities in terms of damping behavior, positional stability and water-structure interactions. To this end, physical model testing of reed-based all-organic gabions in a full-scale facility was performed in this study, demonstrating:
- Artificial floating islands used for bioremediation of aquatic ecosystems can also dampen waves.
- Transmission, reflection and dissipation coefficients as well as the movement behavior are determined in experiments with a large model scale.
- The results show that the artificial floating islands significantly attenuate shorter waves (T ≤ 2.25 s).
- The width of the structure is identified as a key parameter for the damping behavior.
