Perhaps seawall construction has been an essential tool in coastal engineering for centuries. Seawalls are structures designed to safeguard coastlines from erosion, storm surges, and flooding. They can be designed from different materials such as concrete, steel, or timber and can range in dimensions from small barriers to big-scale structures that span kilometers. Explore the function of seawall construction in saving coastal communities and the advantages and drawbacks of seawalls. The Importance of Seawalls in Coastal Protection Coastal regions are increasingly vulnerable to climatic disasters, such as gales, typhoons, and storm floods, which can cause massive wear to infrastructure, belongings, and human life. Seawalls play a vital role in protecting coastal communities from these disasters by acting as a barrier against waves and storm surges, minimizing the amount of impairment caused by flooding and erosion. Moreover, it can also help avert the loss of coastal ecosystems, in
