| Gabions @ East Coast Park

Gabions are strong wired cages filled with crushed rocks. They are stacked up to form a wall and piled up along the shore to prevent or reduce coastal erosion by weakening wave energy.
- Effectiveness
- Cheaper to build ( compared to sea walls, breakwaters and groynes )
- Protects the other coastal protection structures ( Example : Sea walls )
- Ineffectiveness
- Short term protection ( lasts for less than 15 years )
- Easily destroyed by powerful waves during storms
- Rocks are easily eroded away
- Wired cages are corroded easily, and soon rust
- Visitors may hence get cut by rusty metal
- Spoils the natural beauty of the beach
