“…Geotextile tubes (hereafter "geotextile cores") consist of water permeable, sand-sealed geotextiles filled with sand or other granular material [26]. On this basis, the use of geotextile cores has been considered to provide more environmentally friendly dunes than other types of hard solutions [6,7,27]. Certainly, they are effective in preventing flooding and erosion, but there is evidence that they cause adverse effects on beach and dune evolution.…”

“…Certainly, they are effective in preventing flooding and erosion, but there is evidence that they cause adverse effects on beach and dune evolution. For example, beaches with geotextile-core dunes are narrower, with steeper slopes and less sand volume [27]. Under these conditions, when the dunes erode, the wave reflection is increased.…”

“…Finally, social concerns arise, as geotextile cores restrict access and affect the aesthetic and recreational value of the beach [6]. Consequently, some authors, such as Gibeaut et al [29] and Harris and Ellis [27], have suggested that the performance of geotextile-cored dunes is closer to that of a hard solution than that provided by a natural beach dune system.…”

“…In addition, rocky cores can improve the success of dune revegetation efforts because the porous core allows root penetration and water supply for plants to grow more vigorously. Examples of dunes and beaches enhanced with hybrid solutions (plants and cores) are found on beaches in the Mexican Caribbean, and Texas, Los Angeles, Florida, and New Jersey in the USA (see Feagin, [6]; Nordstrom, [7]; Harris and Ellis, [27]) as well as Figueira da Foz, Portugal [30].…”

Coastal dune restoration projects are increasingly seen as a means of protecting the coast against storms, especially with the use of natural (plants), artificial (geotextile tube cores) and hybrid (plants and geotextile tube) elements. As geotextile tube cores have been found to negatively affect dune and beach natural morphodynamics, rocky cores are thus seen as a potential alternative. We carried out laboratory experiments to compare the performance of dunes with rocky cores, geotextile cores, and both types when coupled with planted vegetation. We investigated these elements in the context of scaled mild, moderate, and intense storm conditions. The results showed that dunes with either type of core lost more sand than dunes without cores. The addition of plants generally reduced the erosion across the various options, but most strongly for rocky cores under mild and moderate storm conditions. We also found that dunes with a high density of plants were best for intense conditions. Overall, the use of rocky dune cores, when coupled with plants, is the most suitable and sustainable alternative option in hybrid engineering projects.
