Large-scale erosion can occur on the land next to large bodies of water like lakes and beaches. Different kinds of seawalls can prevent damage from flooding, deterioration, and seasonal water level variations. Experts study the shore conditions to determine the kind of materials best for the seawall, which will help them choose the type of seawall most appropriate for the shore. Therefore, seawall erosion control measures can be achieved using three types of seawalls: vertical walls, coble boulders, and concrete walls.
Vertical walls are strong, upright walls that prevent ocean waves from eroding the shoreline.
They are simple to build and offer sufficient wave protection. Since vertical walls are simpler to construct than other sea walls, they are frequently used. Cobble boulders are preferred in less demanding locations without powerful waves. The enormous boulders that make up the cobble boulder are piled on top of a pile of soil, debris, and small stones. Then, the stones are stacked in clear areas to make room for water to flow. Concrete seawalls are constructions made to shield coastlines from powerful waves. These seawalls are made of massive concrete sections that have been crane-lowered into position and reinforced with steel.
