Abstract (EN): Unidirectional irregular waves of varying significant wave-height and peak period but with a constant spectral shape (JONSWAP spectrum, ¿=3.3) were generated over a sandy 3:20 sloped plane beach to investigate scour fronting a dune erosion control system constructed from geotextiles, slope inclined at 45º. Both passive (i.e., three dune erosion control systems with two configurations) and active (i.e., one nearshore submerged structure with four configurations) structures are investigated. A twodimensional physical movable-bed model simulating the prototype dune-beach systems of Estela, located along the NW Portuguese coast, is employed in this study. The paper presents a brief characterization of the prototype conditions and discusses requirements and limitations on the choice of model scale for the waves, the sediments, and the geotextile materials.
