What percentage of wave energy is dissipated by the top 1 meter of the reef?

The correct percentage of wave energy dissipated by the top 1 meter of the reef is indicative of how effectively coral reefs serve as natural barriers to wave action. Coral reefs play a crucial role in coastal protection, helping to reduce the intensity of waves that reach shorelines.

When waves approach a reef, they interact with the structure of the coral. The intricate formations and physical properties of the reef absorb and reflect a significant amount of wave energy. Research has shown that about 86% of wave energy can be dissipated within the first meter above the reef. This high degree of energy dissipation is critical for protecting coastal ecosystems and human infrastructures from the impacts of strong waves.

Understanding this percentage is essential for evaluating the ecological function of coral reefs and their significance in coastal management. Areas where reefs are healthy can provide greater protection compared to those where reef structures have been degraded. In contrast, options like 50%, 70%, and 100% do not accurately represent the documented scientific understanding of wave energy dissipation in relation to coral reefs, highlighting the distinctive efficiency of reef systems in mitigating wave impacts.
