Consequently, the floods caused by this severe weather were amongst the worst to have ever impacted the UK, with large-scale damage caused in counties such as Somerset, Devon, Dorset, and Cornwall in the south-west, and the Thames Valley in the south-east. The Thames Valley was among the hardest hit, with as many as 14 severe flood warnings issued along the river’s course and water levels so high that parks along the banks of the Thames were completely submerged. Of course, there is no one silver bullet solution that could have prevented the extensive damage and costs that were incurred during these floods or prevented the loss of lives. To be adequately prepared for extreme weather events, all the right boxes must be ticked to prevent the chain of damage that occurs and life-threatening risk that is created, and ideally prevent problems at the source. For example, during the 2013-14 devastating flooding in the UK, Ecocoast had previously installed over 400 Bolina Rope Safety Boom units in the Thames. These booms played a crucial role in protecting critical flood control infrastructure. According to officials, they effectively diverted rapidly oncoming large debris, such as tree logs and branches, mitigating potential damage by redirecting them into a low-risk and easily clearable area. Importantly, these booms are not only designed for environmental protection but also intended to serve as life-saving equipment. Their structure permits two people per float to climb onto the boom without requiring a ladder. Moreover, the attached rope enables them to safely navigate to shore without assistance. This multipurpose functionality makes the boom an invaluable asset, offering crucial support along rivers during severe weather events. Remarkably, among the several hundred units installed at that time, no maintenance or replacements were necessary, despite facing nearly unprecedented conditions. Even today, these units remain in position along the River Thames, demonstrating their enduring reliability. Another example is the River Trent. Notorious for its perilous flooding during storms, the third’s longest river in the UK has frequently altered its course, leading to significant damage to lives and properties along its banks.
Aside from its unpredictable behavior, the river’s path includes numerous canals, weirs and locks, posing hazards for boats and other river traffic navigating its waters. To ensure safety for river traffic, the installation of Bolina Watercraft Safety Boom units has been pivotal. These safety booms have successfully safeguarded various watercraft, from houseboats to narrow boats and barges, rescuing them from potential damage or loss. These interventions have proven critical, particularly when boaters lose control of their watercraft, inadvertently navigating into hazardous zones along the river. Spain boasts similar areas requiring protective
measures. An illustration of this is the installation of Bolina Log Screen Boom units in Galicia, Spain, during 2020. These booms were implemented to safeguard the San Esteban hydroelectric complex, situated in a region known for its remarkably high average rainfall – among the highest in the country. Serving as a flood management solution, these booms were strategically positioned to prevent debris from obstructing the dam gates, ensuring the unimpeded functioning of the hydroelectric complex.
Having equipment that works when it most needs
to, that is reliable, and that provides peace of mind, is invaluable in desperate times. Investing in high- quality, durable equipment and infrastructure is an essential aspect of a successful long-term strategy, particularly at a time when the behaviour of our climate is becoming increasingly uncertain. Working with partners whose products have been tried and tested, whether that be in the real world or in simulated circumstances, is the first step to ensuring that you and the people whose lives and properties you are responsible for are protected.
