This study addresses wave attenuation by vegetation and vegetation-inspired structures, a key topic in eco-engineering given the declining extent of mangrove ecosystems, natural coastal defenses that dissipate wave energy and enhance sediment deposition.To support hybrid ecological–engineering interventions employing cylindrical elements to promote mangrove recovery, a theoretical model is developed to predict solitary-wave attenuation by arrays of emergent or submerged cylinders. The model is validated through DualSPHysics numerical simulations across multiple array configurations and further assessed using laboratory experiments conducted for solitary waves in the presence of a background current. Results show a good agreement between theoretical predictions, numerical outcomes, and laboratory measurements, confirming the model’s reliability for coastal protection and restoration applications.

Abstract
This study addresses wave attenuation by vegetation and vegetation-inspired structures, a key topic in eco-engineering given the declining extent of mangrove ecosystems, natural coastal defenses that dissipate wave energy and enhance sediment deposition.To support hybrid ecological–engineering interventions employing cylindrical elements to promote mangrove recovery, a theoretical model is developed to predict solitary-wave attenuation by arrays of emergent or submerged cylinders. The model is validated through DualSPHysics numerical simulations across multiple array configurations and further assessed using laboratory experiments conducted for solitary waves in the presence of a background current. Results show a good agreement between theoretical predictions, numerical outcomes, and laboratory measurements, confirming the model’s reliability for coastal protection and restoration applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
