Spatial-temporal runoff patterns change of dissolved organic matter(DOM) fluorescence characteristics at inflowing stream of industrial(4TG), urban(AS), and rural(MS) areas in Lake Sihwa. The result of synchronous analysis in 4TG, PLF(Protein-like fluorescence) variation characteristics clearly appeared while no clear peaks appeared in the FLF(Fulvic-like fluorescence) and HLF(Humic-like fluorescence) wavelength ranges. The results of analysis using 3D-EEMs(3-Dimensional Excitation Emission Matrix Spectroscopy) showed a difference that fluorescence distribution and variation clearly appeared in the FLF and HLF regions along with the PLF region and DOM variation over time tended to be similar between the results of the two fluorescence analyses. The results of synchronous analysis in AS showed that PLF, FLF and THLF(Terrestrial-like fluorescence) region peaks were clearer during rainfall than when there was before rainfall. AS showed a distribution characteristics that PLF characteristics did not disappear even during rainfall but continuously appeared during the duration of rainfall. The spatial-temporal DOM variation and distribution characteristics during rainfall appeared through the synchronous method and the 3D-EEMs method showed similar tendencies although in the results of 3D-EEMs analysis.
