An innovative research-based technology has been applied for the first time in Colombia to improve the navigability of the Magdalena river in a zone of the city of Barrancabermeja, Department of Santander. The result of installation of the submerged vane technology demonstrated its effectiveness in sediment management and motivated its further use as a solution to problems of erosion, scour and meander evolution, which are common occurrence in the rivers of the country. Since this 1991 installation, more than 18 projects have been completed and the technical effectiveness of the system has been improved. Compared to traditional solutions, the results demonstrate beneficial economic impacts due to shorter execution times, reduction in annual maintenance costs, and diminished environmental impacts. Characteristics of design and construction and results obtained from five projects are described that are representative of the diversity of conditions and difficulties for the application of this technology in Colombia. Lessons learned for adaptation by river management authorities are derived from the study.

哥伦比亚潜叶技术：五个代表项目

哥伦比亚首次应用了一项基于研究的创新技术，以提高桑坦德省巴兰卡贝梅哈市地区马格达莱纳河的通航性。水下叶片技术的安装结果证明了其在沉积物管理方面的有效性，并促使其进一步用作解决该国河流中常见的侵蚀、冲刷和蜿蜒演变问题的解决方案。自 1991 年安装以来，已经完成了 18 个以上的项目，系统的技术效率得到了提高。与传统解决方案相比，结果表明，由于缩短了执行时间、减少了年度维护成本并减少了对环境的影响，因此产生了有益的经济影响。描述了从五个项目中获得的设计和施工特点以及结果，这些项目代表了哥伦比亚应用该技术的条件和困难的多样性。河流管理当局的适应经验教训来自该研究。
