Threats to beaches have accelerated the coastal destruction. In recent decades, geotextile tubes were used around the world to prevent coastal erosion, to encourage beach nourishment, and to assist mangrove rehabilitation. However, the applications of geotextile tube in sandy and muddy coasts have different concerns as the geological settings are different. Applications of geotextile tubes in sandy beaches were mainly to prevent coastline from further erosion and to nourish the beach. However, for the muddy coasts, mangrove rehabilitation and conservation were additional concerns in coastal management schemes. The mangrove forests are natural barriers which can be found on the muddy coasts of many tropical countries. In this paper, the viability of geotextile tubes in sandy and muddy beaches was analysed. The advantages and disadvantages of the utilization of geotextile tubes in coastal management were discussed based on the experiences from the tropical countries such as Mexico, Malaysia, and Thailand. From the case studies, impressive improvements in coastal restoration after installation of geotextile tubes were shown. Based on the discussion, several recommendations to improve the application of geotextile tubes were suggested in this paper.
对海滩的威胁加速了海岸侵蚀。近几十年来，土工织物管在世界各地被用于防止海岸侵蚀、促进海滩养护以及协助红树林恢复。然而，由于地质条件不同，土工织物管在 sandy 和 muddy 海岸的应用存在不同的问题。土工织物管在沙滩上的应用主要是防止海岸线进一步侵蚀和养护海滩。然而，对于 muddy 海岸，红树林恢复和保护是海岸管理计划中的额外关注点。红树林是许多热带国家 muddy 海岸上的天然屏障。本文分析了土工织物管在 sandy 和 muddy 海滩中的可行性。基于墨西哥、马来西亚和泰国等热带国家的经验，讨论了在海岸管理中使用土工织物管的优缺点。从案例研究中可以看出，安装土工织物管后海岸恢复有显著改善。基于讨论结果，本文提出了一些改进土工织物管应用的建议。
