Geosynthetic-wrap around revetments for shore protection

Geosynthetic structures for shore protection have demonstrably lower construction and lifetime costs than those of hard structures. This paper outlines the recent development of a geosynthetic structure that is commonly used for shore protection: geotextile wrap-around revetments (GWRs). Its advantages are also explained. Model tests described in this paper show that these structures are stable against wave action and that their stability can be increased with some simple modifications. Additionally, GWRs have been shown to adapt extremely well against differential settlement and scour erosion. Knowledge obtained from model tests has facilitated the creation of modified design charts. Efficiency of these systems against storm surges, rising sea level, and tsunami is also discussed. Analyses show that many uncertainties involving these structures remain, but that geosynthetic structures should not be regarded as an alternative shore construction method. Rather, they are a preferable solution for numerous coastal problems.
