马来西亚的海岸线面临海岸侵蚀和海平面上升的威胁。 2015 年国家海岸侵蚀研究报告称，8840 公里海岸线的 15% 目前正在受到侵蚀，其中三分之一属于需要结构保护的关键和重要类别。 2017年马来西亚海平面上升研究显示，海平面平均每年上升0.67-0.74毫米。本研究回顾了马来西亚沿岸选定的沿海保护结构，作为基于沿海管理策略的侵蚀控制和海平面上升适应。岩石护岸和防波堤等硬结构通常用作“坚守阵线”策略中的侵蚀防护系统。增加海堤和土堤的平台高度被认为是一种“适应”方法，可以有效地防止侵蚀，并适应海平面上升。红树林重新种植适合作为一种“有限干预”方法，最大限度地减少这两种威胁的长期影响。然而，海上防波堤、防波堤和土工织物管仅用于保护目的，对于适应海平面上升并不有效。随着海平面不断上升，它们的海岸防护功能也将减弱。综上所述，这次对马来西亚海岸保护的全面审查将有利于相关机构今后的评估。
The shoreline of Malaysia is exposed to threats of coastal erosion and a rise of sea level. The National Coastal Erosion Study, 2015 reported that 15% of an 8840 km shoreline is currently eroding, where one-third of those falls under the critical and significant categories that require structural protection. The Study of Sea Level Rise in Malaysia, 2017 presented a sea-level increase of 0.67–0.74 mm on average yearly. This study reviewed selected coastal protection structures along the shoreline of Malaysia as an erosion control and sea-level rise adaptation based on coastal management strategies. Hard structures such as rock revetment and breakwater are commonly used as erosion protection systems in the “hold the line” strategy. Increased platform level of seawalls and earth bunds, considered as an “adaptation” approach, are effective in erosion protection and are adaptive to sea-level rise. Mangrove replanting is suitable as a “limited intervention” approach in minimizing the long-term impact of both threats. However, offshore breakwater, groyne, and geotextile tubes are solely for protection purposes and are not as effective for sea-level rise adaptation. As the sea level is continuously increasing, their function as coastal protection will also become less effective. In summary, this comprehensive review on coastal protection in Malaysia will benefit the related agencies on the future assessment.
