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).

本数据集提供了全面的测量数据与模型输出结果，用于研究近海水产养殖区域的沉积物再悬浮动力学过程。本数据集的采集旨在量化表征波浪与流场诱导切应力对浅海海域沉积物输运的相对贡献。主要研究结果表明，波浪诱导切应力（wave-induced shear stress, τ_w）是沉积物再悬浮的主导驱动因素，在两个研究站位的总切应力占比均超过80%。流场诱导切应力（current-induced shear stress, τ_c）的影响则极为有限（不足10%）。该非线性模型揭示了波流相互作用的增强效应，尤其当波浪与流场呈近似垂直相向（偏转角≈90°）时效果最为显著。模型验证结果显示，相较于粗颗粒沉积物站位（YB），以粉砂为主的沉积环境（EL）的模型预测性能更优。
