Data for: Mechanisms Regulating the Expansion Pathways of Detached Low-salinity Water Patches from the Changjiang River Diluted Water

This dataset contains processed outputs from the SCHISM (Semi‑implicit Cross‑scale Hydroscience Integrated System Model) for the study “Mechanisms Regulating the Expansion Pathways of Detached Low-salinity Water Patches from the Changjiang River Diluted Water”. All data files are provided as MATLAB (.mat) formatted arrays, ready for analysis and reproduction of the figures presented in the paper.Schism _ grid.mat is a horizontal grid, schism _ modeled _ salt _ E.mat and schism _ modeled _ salt _ NE.mat are the salinity data of CaseE and CaseNE on the day of simulated detachment, schism _ modeled _ currenty _ E.mat and schism _ modeled _ currenty _ NE.mat are the flow field data of CaseE and CaseNE on the day of simulated detachment, schism _ momentum _ E.mat and schism _ momentum _ NE.mat are the momentum data of CaseE and CaseNE, respectively.The variables within each file represent the final, processed model outputs used for plotting.
