ABSTRACT Human settlements in the Sundarbans deltaic region of India have adopted a method of erecting embankments along the riverside to prevent river water from spilling over into the colonized areas. These embankments develop undercuts at the toe region that lead to failure from the swirling currents coupled with tidal surges and strong winds. To protect the embankment from erosion, the embankment face is covered with bamboo logs, as bamboo is easily available locally and is economically viable. However, from field investigations the use of bamboo logs for the prevention of embankment erosion is found to be ineffective in the Sundarbans region. The present investigation was carried out to develop insight into why the use of bamboo logs for embankment protection does not represent an optimal solution for bank stabilization. The current work emphasizes an appraisal of the turbulent flow characteristics in proximity to the bamboo logs and sediment bank interface.

评估竹原木在河岸稳定中的水力性能：印度孙德尔本斯的案例研究

摘要 印度孙德尔本斯三角洲地区的人类住区采取了一种沿河岸筑堤​​的方法，以防止河水溢出到殖民地地区。这些堤防在脚趾区域形成底切，导致涡流以及潮汐和强风的破坏。为了保护堤防免受侵蚀，堤防表面覆盖着竹原木，因为竹子在当地很容易获得，而且在经济上是可行的。然而，从实地调查中发现，在孙德尔本斯地区使用竹原木来防止路堤侵蚀是无效的。进行本调查是为了深入了解为什么使用竹原木保护堤坝并不是稳定堤岸的最佳解决方案。
