Blockage of cross-drainage hydraulic structures is a significant concern in water resources and civil engineering projects, particularly in urban areas experiencing increased debris supply. During storms or floods, debris can accumulate and restrict the flow capacity of these structures, leading to potential failures and adverse impacts on flood levels. While some argue that blockage at culverts is a non-issue, scientific research supports its significance in specific regions. However, in context of rivers and dams, blockage by Large Wood (LW) is an established issue with plenty of research in terms of its hydraulic impacts, dynamics, modeling and scouring impacts. Specifically in Australasia the Australian Rainfall and Runoff (ARR) initiative recognized the importance of studying blockage at culverts and introduced guidelines incorporating it into design and modeling. These guidelines also included post flood visual inspections of structures to understand blockage, however, this approach has been criticized by hydraulic engineers arguing that post flood visuals can not be considered as the representation of the peak floods blockage. Recently, an approach of using visual information to interpret the blockage has been adopted as a new dimension to the problem. This paper, therefore, highlights the advances, challenges, and opportunities in studying blockage, emphasizing the need for data-driven approaches and interdisciplinary collaboration. Understanding and addressing blockage are crucial for ensuring the efficient operation and longevity of hydraulic structures and promoting the resilience of infrastructure systems in the face of evolving environmental conditions.
交叉排水水工建筑物的堵塞是水资源和土木工程项目中的一个重大问题，尤其是在碎屑供应增加的城市地区。在暴风雨或洪水期间，碎屑会堆积并限制这些建筑物的泄流能力，从而导致潜在的故障以及对洪水水位产生不利影响。虽然有些人认为涵洞堵塞是一个无关紧要的问题，但科学研究支持其在特定地区的重要性。然而，在河流和大坝的背景下，大木头（LW）造成的堵塞是一个既定问题，在其水力影响、动力学、建模和冲刷影响方面已有大量研究。特别是在澳大拉西亚地区，澳大利亚降雨与径流（ARR）倡议认识到研究涵洞堵塞的重要性，并引入了将其纳入设计和建模的指导方针。这些指导方针还包括对建筑物进行洪水后目视检查以了解堵塞情况，然而，这种方法受到了水利工程师的批评，他们认为洪水后目视检查不能被视为对峰值洪水堵塞情况的反映。最近，一种利用视觉信息来解释堵塞情况的方法已被作为该问题的一个新维度采用。因此，本文强调了在研究堵塞方面的进展、挑战和机遇，强调了数据驱动方法和跨学科合作的必要性。了解和解决堵塞问题对于确保水工建筑物的高效运行和使用寿命以及在不断变化的环境条件下提高基础设施系统的恢复力至关重要。
