3 Types of Coastal Seawalls

Seawalls / December 1, 2021

Climate change is a pressing issue in the twenty-first century. With its negative consequences on the environment all around the world, climate change needs to be a priority. The rise in sea levels is a key result of climate change.

Rising sea levels produce an increase in waves and tides, prompting the construction of seawalls to protect various shorelines. Seawalls help minimize the aggressiveness of coastal waves, erosion, or other harmful weather threats.

They can range in size from massive structures to offer harbor protection to modest structures to protect a boardwalk, a beach, or apartment. These seawalls are barriers defending the shores and fighting off water erosion.

It can assist safeguard any structure near the shore, such as a home, in addition to reducing erosion. Furthermore, several conservation measures, including building seawalls, are required to maintain the integrity of these beaches.

In this article, we will look at different types of seawalls and their function.

Vertical Seawalls

First up on the list of the different types coastal of seawalls is vertical seawalls. As the name suggests, this type of seawall has a vertical structure to help keep large tidal power from undermining the beach. In regions where the waves exceed two meters, we propose this form of barrier. This is a well-known alternative since it provides excellent resistance and durability. However, keep in mind that the tide is steady and forceful, thus it is natural for it to damage the structure.

Understanding the geological environment is helpful when choosing which seawall is best for specific locations. However, this can be hard because we’re talking about natural, as well as unpredictable occurrences like tides, undertows, currents, and winds, and more. There are patterns that can be studied to determine the strength and patterns of tides and waves to ensure the right selection.

Another important factor to take into consideration when choosing which seawall is the best option is the drainage. If water or ocean debris passes the seawall a filter must be present to prevent the entrance of objects through the wall.

Curved Seawalls

Curved seawalls, with their construction mimicking a wave, are among the most popular. The shape helps reduce the wave’s powerful effect by causing the water to float upward, following the shape of a natural wave.

One great insight to know about its foundation is it’s often made of poured concrete. One of the most significant benefits of this choice is that it is intended to decrease undercutting at the wall’s base.

We promote them because they are quite good at distributing wave energy, which provides an additional defense to the foundation. Homeowners who want to settle near the seaside can benefit from these seawalls.

With this in mind, it provides more protection from natural disasters and the flow of water. Curved seawalls are strong barriers that may survive for many years without needing to be repaired.

Mound Seawalls

Last on the list of the different types of coastal seawalls is mound seawalls. Walls made of cement walls and gravel have some of the most prevalent solutions, providing a number of advantages. For starters,  it’s less expensive than the prior two alternatives. Secondly,  It is often constructed atop debris and rock mounds. Finally, the slope’s form cuts which decrease wave strikes along the coast.
