Abstract
    Large scale model tests have been performed on a scale 1:5 in the ICTS-CIEM to test the stability of sand-filled geosystems, both tube and bags, and their effect on the morphological evolution of a beach profile. Tube and bags were buried in sand at the upper part of a beach profile with a slope 1:15 in the area where it was transitioning to a beach berm (horizontal flat section). Erosion of the beach during the experiment exposes the tube and bags to direct wave attack. Tests were done under the action of irregular waves with a significant wave height of 2.5 m in prototype, also the effect of two different water levels was considered. Under these conditions the erosion at the seaward side of the tube and bags was limited. Remarkable there was more erosion around the bags. As a consequence of the limited erosion the stability of the structure was never a problem.
