Abstract

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

评估竹木原木在河岸稳定中的水力性能:印度桑达尔班斯案例研究

摘要

印度Sundarbans三角洲地区的人类住区采取了一种在河边竖立堤防的方法,以防止河水溢出到殖民地。这些路堤在脚趾区域形成底切,由于旋流,潮涌和强风而导致破坏。为了保护路堤免受侵蚀,路堤的表面覆盖了竹原木,因为竹子很容易在当地购得,并且在经济上可行。但是,从野外调查来看,在桑达尔班地区发现使用竹木预防路堤侵蚀是无效的。进行本调查的目的是为了深入了解为何使用竹木保护路堤不能为银行稳定提供典型的解决方案。
