Hydraulic Performance of Geotextile Sand Containers for Coastal Defenses

Laboratory experiments were performed in the wave flume of Laboratorio di Idraulica e Costruzioni Marittime Università Politecnica delle Marche (Ancona, Italy) to study hydrodynamic performance coastal protection structures made a new type geotextile sand containers (GSCs). Such are used as softer and flexible alternatives traditional hard defenses concrete or rubble mound material. The GSC can also be temporary protections during winter period. physical model reproduced two main configurations: former one, GSCs revetments with three different slopes. In latter applied make detached submerged breakwaters submergences berm widths. geometric scale models was 1:10, weight each prototype 5 t. material characteristics by using Reynolds Froude similarity criteria, respectively. Reflection coefficients hydraulic stability behaviors for revetments, well transmission piling-up amount breakwaters, obtained.
