Data for Optimising sediment resuspension processes for improved modelling of solid waste in coastal aquaculture

This dataset provides comprehensive measurements and model outputs for studying sediment resuspension dynamics in coastal aquaculture sites. The data were collected to characterize the relative contributions of wave- and current-induced shear stresses on sediment transport in shallow marine environments. Key findings demonstrate that wave-induced shear stress (τ_w) was the dominant driver of sediment resuspension, contributing over 80% of total shear stress at both study sites. Current-induced shear stress (τ_c) showed minimal influence (<10%). The non-linear model revealed enhanced wave-current interactions, particularly when waves and currents approached perpendicular orientations (deflection angle ≈90°). Model validation showed better performance in silt-dominated environments (EL) compared to coarser sediment sites (YB).本数据集提供了用于研究近海水产养殖区域沉积物再悬浮动力学的综合测量数据与模型输出结果。本次数据采集旨在表征浅海环境中波浪与海流诱导剪切应力对沉积物输运的相对贡献。核心研究结果表明，波浪诱导剪切应力（τ_w）是沉积物再悬浮的主导驱动因素，在两个研究站点的总剪切应力占比均超过80%；海流诱导剪切应力（τ_c）的影响则相对微弱，占比不足10%。该非线性模型揭示了增强型波浪-海流相互作用现象，尤其当波浪与海流呈垂直方向（偏转角≈90°）时，该现象更为显著。模型验证结果显示，相较于粗颗粒沉积物站点（YB），该模型在以粉砂为主的环境（EL）中表现更优。
