Wave attenuation by cultivated seaweeds: A linearized analytical model

Morgane Aline Elsa Marine Weiss

An analytical framework is presented to describe the attenuation of regular and irregular waves propagating over floating seaweed farms. Kelp blades suspended on longlines are modelled, as a first approximation, as rigid bars rotating around their upper en ...
