This repository contains supporting data for *Wave-influenced Delta Morphodynamics, Long-term Sediment Bypass and Trapping Controlled by Relative Magnitudes of Riverine and Wave-driven Sediment Transport,* submitted to Geophysical Research Letters. Delft3D Config for Q1000Qs100Hs15.docx → contains configuration file info for running the Delft3d simulation Q1000Qs100Hs15. Matlab 2022b was used to load Delft3D output files and process the data. WaveDelta_Depth&DepositThick.mat Contains: Depth → timesteps x 322 x 142. Timesteps are variable for each simulation. MSEDRiverSum → 4 x 322 x 142. Mass of sediments from riverine source at four intermediate timesteps. MSEDWaveSum → 4 x 322 x 142. Mass of sediments from longshore transport (LSTUp) source at four intermediate timesteps. VolRiverSum → 322 x 142. Final Volume of sediments from riverine source. VolWaveSum → 322 x 142. Final Volume of sediments from longshore transport (LSTUp) source. XCOR & YCOR are the X and Y grid coordinate locations for maps (322 x 142). Shift2&4km are used for cases highly skewed downdrift to correct for 0 location at the river mouth. Cerc_formula.mlx Computes CERC longshore transport for the simulation conditions. J.mlx calculates river mouth balance (J) values (Nienhuis et al. (2016)) presented in Figure S4. Additional 114 Figures are provided in Data_Visualization_Figures.rar to show Depth and thickness; subaqueous morphodynamics and depth and sediment transport (quiver).本仓库为提交给《Geophysical Research Letters》的论文《受波浪调控的三角洲地貌动力学、由径流与波浪输沙相对强度调控的长期泥沙绕行与沉积捕获》提供支撑数据。 Delft3D Config for Q1000Qs100Hs15.docx 包含运行Delft3D模拟Q1000Qs100Hs15的配置文件相关信息。 本次研究采用Matlab 2022b加载Delft3D输出文件并完成数据处理。 WaveDelta_Depth&DepositThick.mat 包含如下数据： - Depth：维度为时间步长×322×142，各模拟工况的时间步长为变量。 - MSEDRiverSum：维度为4×322×142，代表4个中间时间步下径流来源泥沙的总质量。 - MSEDWaveSum：维度为4×322×142，代表4个中间时间步下沿岸输沙（longshore transport, LSTUp）来源泥沙的总质量。 - VolRiverSum：维度为322×142，代表径流来源泥沙的最终总容积。 - VolWaveSum：维度为322×142，代表沿岸输沙（longshore transport, LSTUp）来源泥沙的最终总容积。 - XCOR与YCOR为制图所用的X、Y网格坐标，维度均为322×142。 - Shift2&4km 用于向海侧高度偏倚的工况，以校正河口处的零点位置。 Cerc_formula.mlx 用于根据模拟工况计算CERC沿岸输沙量。 J.mlx 用于计算河口平衡（J）值（引用Nienhuis等(2016)的研究），对应补充图S4。 此外，Data_Visualization_Figures.rar 中包含114张补充可视化图表，用于展示水深与沉积厚度、水下地貌动力学特征、水深与泥沙输运矢量场。
