seawall

A seawall is a protective structure built along coastlines to prevent coastal erosion and protect against storm surges and high waves. Typically made from concrete, stone, or other durable materials, seawalls act as barriers that absorb and deflect the energy of incoming water. They help safeguard properties, roads, and ecosystems located near the shore. While effective in providing immediate protection, seawalls can sometimes lead to increased erosion in adjacent areas and may require regular maintenance to remain effective over time.
