摘要

河道治理对于保护河岸免受侵蚀和防止洪水破坏至关重要。多年来,人们一直在使用各种成熟的方法,如河刺、堤坝和护岸。目前,研究人员正在研究一种新型的河道治理方法,即 "带状结构",旨在证明其作为现有结构潜在替代品的成本效益。竹绷带技术可有效控制侵蚀,促进河流沉积,减少泥沙负荷。可生物降解的竹子易于获得且成本效益高,可确保对水生生物的危害降到最低。不过,这些结构在一个季风季节后就需要更换,因此只适合在低排水量、不沉没的条件下进行短期河道治理。本研究分析了带状结构周围的冲刷情况,强调了进一步研究解决速度分布差异和优化冲刷控制的必要性。数值模拟的优缺点凸显了人工神经网络、遗传算法和计算流体力学在不同调查方面的适用性。

Bamboo Bandalling Technique for River Bank Protection and Flood Control – A Critical Review
River training is crucial for safeguarding river banks against erosion and preventing damage during floods. Various established methods like spurs, dykes, and revetments have been employed for many years. Researchers are currently investigating a novel river training approach known as bandal-like structures, aiming to demonstrate their cost-effectiveness as a potential alternative to existing structures. The bamboo bandalling technique effectively controls erosion and promotes sedimentation in rivers, reducing sediment loads. Biodegradable bamboo, readily available and cost-effective, ensures minimal harm to aquatic life. However, these structures require replacement after a single monsoon season, making them suitable for short-term river training in low-discharge, unsubmerged conditions. The current study analyzes scour around bandalling structures, emphasizing the need for further research to address discrepancies in velocity distribution and optimize scour control. Numerical simulation strengths and weaknesses highlight the suitability of Artificial Neural Networks, Genetic Algorithms, and Computational Fluid Dynamics for different aspects of the investigation.
