Data corresponding to experiments published in: Villanueva, R., Paul, M., & Schlurmann, T. (in review). Flexible anchored mats of artificial seagrass for restoration: wave dynamics and agreement with contemporary models. Scientific Reports The data correspond to the measurements done on a wave flume for wave interaction with submerged anchored base layers and artificial vegetation. The experiments were done within the framework of the SeaArt project (see the institute's website). The datasets are organized through a specific nomenclature described in the text file Nomenclature.txt.
