Geotextile tube usage for coastal shore protection

Usage of the geotextile based artificial soil materials recently increase in coastal protection applications. These materials are become important such as temporary solutions, lack of supplying natural materials (rock), quick solutions cases. One of the most important applications of geotextile application in coastal engineering is one or several layer geotubes overlap each other replacements as height as wave run up in the coast line or near protecting coastal area. Stability of these type of structures are generally tested by numerically and wave loads determined over geotubes. In the presented paper, numerical model generated extreme wave loads over the geotube was compared with a bearing capacity of geosynthetic in Black Sea coast of Turkey for protecting filled zone.
