Barriers & booms |
Above: Ecocoast (previously Bolina) installed 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
This requires robust design and construction to
ensure the structures can maintain their integrity and functionality even in the face of nature’s fury. Maintenance requirements present an ongoing challenge for hydropower operators. Regular inspection and maintenance are crucial to ensure the continued effectiveness of boom systems. This includes removing accumulated debris and repairing any damage to the structure. The need for consistent upkeep can be resource-intensive, requiring dedicated personnel and equipment.

technology As the hydropower industry continues to evolve, so too will the technology behind barriers and booms. One exciting development on the horizon is the concept of “smart booms.” These advanced systems would integrate sensors and IoT technology to provide real- time data on debris accumulation, water quality, and structural integrity. This would allow for more proactive management and maintenance of boom systems, potentially improving their efficiency and longevity. The push for greater environmental sustainability
is likely to drive the development of even more eco- friendly materials for boom construction. Researchers and engineers are continually exploring new materials that can offer the necessary strength and durability while minimizing environmental impact. Automated debris removal systems represent another promising area of development. These systems could significantly reduce the manual labor requirements associated with boom maintenance, making the process more efficient and cost-effective. Imagine robotic systems that could autonomously detect and remove debris from booms, ensuring they remain clear and functional with minimal human intervention.
Looking further into the future, we may see the emergence of multi-functional barriers. These

innovative structures could serve additional purposes beyond their primary functions of debris control and safety. For instance, they might be designed to support aquatic habitats, providing refuge for fish or supporting the growth of beneficial aquatic plants. Some visionaries even suggest integrating small hydrokinetic turbines into these barriers, allowing them to generate small amounts of additional power and further enhancing the efficiency of hydropower installations. As these trends develop, we can expect to see barriers and booms that are not only more effective at their primary tasks but also contribute more broadly to the sustainability and efficiency of hydropower operations.
Conclusion
Barriers and booms have become an integral part of modern hydropower operations, offering solutions to a range of challenges from debris management to public safety. As the industry continues to prioritize efficiency, safety, and environmental stewardship, these floating structures will undoubtedly play an increasingly important role. The evolution from simple log booms to sophisticated engineered systems demonstrates the hydropower industry’s commitment to innovation and continuous improvement. By effectively managing debris, enhancing public safety, and protecting critical infrastructure, barriers and booms contribute significantly to the sustainable operation of hydropower plants worldwide. As we look to the future, continued advancements in
materials science, engineering, and smart technology promise to further enhance the capabilities of these essential hydropower accessories. Whether it’s improving debris management efficiency, bolstering safety measures, or finding new ways to harmonize power generation with environmental conservation, barriers and booms will remain at the forefront of hydropower innovation.
