The Advantages and Disadvantages of Seawalls

Seawalls are constructions built to protect the shoreline from the effects of waves and surges. They serve as barriers that redirect waves back to the water, preventing erosion, and flooding on the shore. While seawalls have numerous advantages, they also have disadvantages that can impact the environment, accessibility, and cost of construction. This article aims to provide you with both the benefits and drawbacks of seawalls. It is intended to guide individuals who are thinking of constructing one, so they can make informed decisions.

Advantages of Building Seawalls

One of the primary reasons people consider seawalls is their ability to prevent erosion and flooding caused by waves. Seawalls offer protection to homes and properties by keeping the surrounding soil safe and free from erosion. The advantages of seawalls include:

• Prevention of erosion and flooding caused by waves - Coastal areas are prone to erosion and flooding, which can cause significant damage to buildings and infrastructure. Seawalls serve as barriers that redirect the energy of waves back to the water, preventing erosion and flooding on the shore.
• Protection of homes and properties from erosion and surge flooding - Seawalls provide a frontier between the sea and the land, preventing damage to homes and properties from wave energy. They also reduce the impact of surge flooding by blocking the water from getting to the upland.
• Increased safety for residents and visitors - Seawalls offer increased safety for people who want to spend time along the shoreline. They provide a stable barrier that reduces the risk of injury and prevents accidents caused by waves and surges.
• Prevention of damage to the environment and wildlife - Seawalls protect the environment and wildlife from the erosive forces of waves. Sediment can harm marine life and disrupt the ecosystem, but using prevention methods can keep it from getting into the water.
• Creation of a frontier between the sea and the land - Seawalls are structures that separate the sea from the land, reducing the risk of damage from wave energy.
• Encouragement of investment within the area - Seawalls provide stability and security, making the surrounding area a safer place for investments. The increased safety and protection offered by seawalls encourage investments within the area.
• Durability and ease of maintenance and modification - Seawalls can be durable if they are well maintained and repaired. They can also be easily adjusted, repaired, and modified by experts to enhance their performance.

Disadvantages of Seawalls

While seawalls offer numerous advantages, they also have several disadvantages that can impact their effectiveness and cost of construction. Some of these disadvantages include:

• High material and construction costs - Seawalls require specific materials and designs to be effective. For people with limited budgets, the high cost of construction and materials can make it difficult to proceed.
• Possibility of overtopping during high water levels - During high water levels, some seawalls can become overtopped, leading to flooding and damage on the upland.
• Formation of a steeped appearance and effect on the surrounding environment - When seawater hits the seawalls, it causes the area to move inland, forming a steeped appearance that can impact the surrounding environment.
• Need for the right designs and patterns for maximum performance - Seawalls require specific designs and patterns to be effective. Poorly designed seawalls can lead to damage to the upland and ineffective protection from wave energy.
• Blockage of access to people with disabilities - Seawalls can block access to people living with disabilities, which can pose a problem if the beach surrounded by the seawall is for recreational activities.
• Blockage of sediments and impact on beach amenity value - Seawalls block sediments from getting to the adjacent coastline, which is crucial in enhancing beach amenity value.
• Importance of careful analysis and experienced minds in construction - Seawalls require careful analysis and experienced minds in their construction to ensure that they are effective. Poorly constructed seawalls can lead to damage on the upland and inefficient protection from wave energy.

Seawalls can provide numerous benefits, from protecting homes and properties from erosion and surge flooding to providing increased safety for residents and visitors.. They also have several disadvantages that should be considered before investing in constructing a seawall. If you decide that the benefits outweigh the drawbacks, it is vital to select a reliable and efficient design and construction team to guarantee that your seawall will effectively safeguard your property.
