Abstract (EN): das Neves, L.; Lopes, M.L.; Veloso-Gomes, F., and Taveira-Pinto, F., 2011. Experimental Study on the Effect of Geotextile Encapsulated-Sand Systems on the Frontal Beach, SI 64 (Proceedings of the 11th International Coastal Symposium), 2027 - 2031. Szczecin, Poland, ISSN 0749-0208 This paper presents an analysis of a series of laboratory measurements of wave-induced morphodynamic changes across a simulated beach protected by a number of erosion control systems constructed from geotextiles and subjected to irregular waves of varying wave height and peak period but with a constant spectral shape (JONSWAP spectrum, gamma=3.3). The objectives of such experimental work were to investigate the efficiency of various systems in maintaining a beach and in protecting the shoreline. For this purpose different models of active and passive coastal defence schemes have been set-up to run on similar hydrodynamic and morphodynamic conditions. The intercomparison carried out on the hydrodynamic and morphodynamic output produced by each protection scheme focused on the scour development and more widespread beach lowering. The next step was to increase understanding of the response of the beach under persistent erosional conditions and under periods of erosion followed by infilling and again erosion.
