Hard works (groins, detached breakwaters) induce steady hydrodynamic behaviours that can lead to local problems such as erosive gradients. These hindrances may be exacerbated at urban areas due to climate change and population pressure. Submerged vegetation may be a cost-effective solution for damping hydrodynamic forcings, plus alleviating some of the hard work drawbacks. The aim of this work is to evaluate the feasibility of submerged vegetation for attenuating wave energy at an urban Romanian beach. Such analysis will be conducted with numerical modelling.
