Driftwood is abundant in coastal zones, and is increasingly being incorporated in nature-based shore protection and restoration projects. However, accumulations of driftwood, and their mobilization by storms or other disturbances, can pose hazards to coastal communities, infrastructure, and ecosystems. An improved understanding of driftwood dynamics in nearshore, wave-dominated environments is needed to inform sustainable use and management of wood in coastal zones. An optical tracking technique was applied to quantify mean transport and dispersion of driftwood in a 1/30 Froude-scaled coastal model exposed to oblique waves. The results provided new insight to factors controlling driftwood mobility and dispersion on beaches exposed to oblique waves, including the effects of sea state, wave-induced currents and circulation, water levels, driftwood length, driftwood roughness, driftwood buoyancy, and coastal structures.

应用光学跟踪技术来表征模型浮木的近岸波浪驱动传输和色散

浮木在沿海地区丰富，并且越来越多地被纳入基于自然的海岸保护和恢复项目。然而，浮木的堆积以及风暴或其他干扰导致的流动可能对沿海社区、基础设施和生态系统造成危害。需要更好地了解近岸、波浪主导环境中的浮木动态，以便为沿海地区木材的可持续利用和管理提供信息。应用光学跟踪技术来量化暴露于斜波的 1/30 Froude 比例海岸模型中浮木的平均传输和分散。研究结果为控制暴露于斜波的海滩上的浮木流动性和分散性的因素提供了新的见解，包括海况、波浪引起的水流和环流、水位、浮木长度、浮木粗糙度、浮木浮力和沿海结构的影响。
