A seawall is a structure built along coastlines to protect the land from the effects of waves and erosion. These walls are typically made of concrete, stone, or other durable materials and are designed to absorb and deflect the energy of incoming water. Seawalls help to prevent flooding and protect coastal properties and infrastructure from damage. In addition to their protective function, seawalls can also impact local ecosystems. They may alter natural habitats and affect the movement of sediment along the shore. While they provide immediate safety benefits, the long-term effects on marine life and coastal environments are important considerations in coastal management.
