Abstract

Solid material sources, such as sediment, large wood, and vehicles, intensify flash flood hazards. This paper provides a detailed review of processes involving the recruitment, entrainment, transport, and blockage dynamics of various solid material sources. Results indicate that sediment supplied by processes like landslides and debris flows can obstruct river channels, leading to a sudden increase in flash flood levels. The failure of a barrier dam results in an expansion of downstream inundation areas. Large wood and floating vehicles transported by flash floods and debris flows may directly impact and destroy built structures or form blockages at built structures. Blockages lead to a backwater rise, and the sudden amplification of flow during the failure of these blockages causes more severe disasters. Based on these analyses, the paper proposes future research directions primarily focusing on the changes in sediment burial processes caused by the sheltering effects of building groups. Furthermore, the study aims to investigate the flow amplification effects of large wood and vehicle blockage.

山区环境中受各种固体物质来源影响的山洪灾害综述
泥沙、大型木材和车辆等固体物质源会加剧山洪灾害。本文详细回顾了各种固体物质源的汇集、夹带、运输和阻塞动态过程。结果表明,山体滑坡和泥石流等过程提供的泥沙会阻塞河道,导致山洪暴发水位突然上升。拦水坝的溃决会导致下游淹没区扩大。山洪和泥石流携带的大型木材和漂浮物可能会直接冲击和摧毁已建建筑物,或在已建建筑物处形成堵塞。堵塞物会导致回水上升,而在这些堵塞物失效时,水流会突然增大,从而造成更严重的灾害。根据上述分析,本文提出了未来的研究方向,主要集中在建筑群体的遮挡效应引起的沉积物掩埋过程的变化。此外,该研究还旨在调查大型木材和车辆堵塞的流量放大效应。
