Large-scale investigation of wave dampening characteristics of organic, artificial floating islands

The concept of floating vegetation-based islands for the bioremediation aquatic ecosystems is well known. Less so, their hydrodynamic capabilities regarding damping performance, positional stability and water-structure interactions. To this end, physical model tests with fully organic, reed-based gabions were carried out in a large-scale facility study. initial, reflected, transmitted waves recorded analyzed transmission reflection coefficients. A motion tracking system was utilized to allow an investigation artificial under waves. results show that significantly dampen shorter wave period T ? 2.25 s. incident reduced by 50% smallest periods ( = 1.5 s). are reflected between 20 same period. energy dissipated up 85% height (H 0.10 m, comparable performance more traditional breakwaters discussed as width structure key parameter layout rivers still waters performance. • Artificial based used can also Transmission, dissipation coefficients alongside behavior determined experiments. identified regard
