Floods can be extremely detrimental to the life and property of people living in flood-prone areas. Not only do they cause destruction of homes and infrastructure, but they also lead to loss of lives. Governments across the world take extensive measures to mitigate the loss of life and property by investing in projects that can prevent or reduce flooding. One such effective method is the use of cofferdams. In this blog, we will discuss the benefits of cofferdams in flood protection.
Environmentally friendly: One of the significant benefits of cofferdams in flood protection is that they are eco-friendly structures. Unlike the conventional dams, cofferdams are temporary and do not cause a large-scale disturbance in their surrounding ecosystems. Due to their lesser impact on the environment, they have been increasingly favored by governments as well as non-governmental organizations.
Quick installation: One of the critical advantages of cofferdams is their ease of installation. The cofferdam wall can be erected fast to form an enclosed space without the need for heavy machinery or equipment. This makes it a go-to solution for emergency situations. Additionally, they can be reconfigured and adjusted according to the changing riverbeds, making them flexible.
Increased flood protection: During instances of flooding, it is imperative to ensure there is no breach in the water barrier, and that it remains intact. The cofferdam’s design ensures that the water pressure is evenly distributed while maintaining the structural integrity of the barrier. The barrier effectively prevents the inland water level from rising, thereby minimizing the flood impact.
Multipurpose function: Cofferdams are versatile structures that can be designed to serve multiple purposes. They can be used for temporary structures like the construction of bridges or permanent structures like marine heads, harbors, and ports. Apart from that, they can also facilitate water transport, regulate water levels, and play a critical role in water management during natural calamities such as flooding.
Lower maintenance cost: Due to their simple design and temporary nature, cofferdams are relatively low in maintenance costs compared to their conventional counterparts. The material used in their construction is relatively inexpensive, and it can be dismantled and reused, adding further cost savings.
What is a cofferdam?
A cofferdam is a temporary structure used to create a dry space in a water-logged area. Cofferdams are often used in construction projects such as bridges, dams, locks, and harbors, where workers need to work on dry land. Additionally, they are commonly used when maintaining the integrity of riverbanks and water bodies during floods. A cofferdam creates an enclosed area around the site that is to be protected to prevent water from flowing in.
Advantages over sandbags
Sandbags are a the most commonly used tool for flood mitigation because they are readily available and small, thus easier to handle. For instance, sandbags can be time-consuming to assemble and require a considerable workforce for installation. They also do not work well in areas with high water flow and waves.
Unlike sandbags, cofferdams are designed to be water-tight structures that do not leak. Cofferdams are also faster to install and require less labor to construct than sandbags. Cofferdams can be placed into position using a crane. Previously installed coffer dams can also be reused in different locations, saving both time, effort, and money.
Cofferdams have been successfully implemented in large structures such as hydroelectric dams, locks, and shipbuilding docks. They are also used in various industries such as oil and gas, mining, and wastewater treatment, and to repair underwater pipelines. Cofferdams are ideal for creating a dry work environment under water to carry out tasks.
Advantages of cofferdams in flood prevention
Cofferdams have numerous advantages in flood protection. They provide an excellent solution to keep water out of the construction site, allowing workers to carry on with the project regardless of the weather or season. In addition, cofferdams reduce the risk of soil erosion in the banks of water bodies and rivers. The temporary structures help prevent soil erosion as water flows are directed around the construction site.
Aqua-Barrier cofferdams can also protect commercial and residential properties near water bodies and riverbanks or areas that are prone to flooding. And once the flood waters have receded, you’re able to store the cofferdams for months or even years at a time until the next flood event occurs. New Aqua-Barriers can be reused on average 15-20 times and have a shelf life of 20+ years – thus proving to be a cost effective and reliable investment.
