Artificial beaches protect coastlines from storm surges, preserving resources for decades.
Artificial beaches can protect coastlines from erosion caused by storm surges. By using medium sand, a beach can be constructed with a width of 80-140 meters and a volume of 1.3-3.2 million cubic meters per kilometer. This design can retain over half of its initial volume even after 30 years. The beach profiles are minimally deformed during extreme storms, ensuring long-term effectiveness in coastal protection.
