0623 is the first day of water release phase (WRP) and 0710 is the first day of sediment flushing phase (SFP) at Lijin station during observation. The blue line in (e), (f), (g), and (h) represents WF at Lijin station, and the gray line indicates SSC in the water body. The different colors in (e), (f), and (h) represent pre-WSRS (June 21st and June 22nd), the first half of the water diversion stage (June 23rd–July 1st), the second half of the water diversion stage (July 2nd–July 9th) and the sediment regulation stage (July 10th–July 12th) respectively. a The data of water flow (WF) and suspended sediment concentration (SSC) from Lijin station; b particulate organic carbon (POC) and dissolved organic carbon (DOC) concentrations during WSRS; c the a350 value of POM, a350-P; d the fluorescence intensity of POM, F-POM; e the a350 value of DOM, a350-D f the spectral slope of DOM, SR-D; g the fluorescence intensity of DOM, FDOM; h the humification index of DOM, HIX-D.
