AB: In the Gwangneung forest, a Korean National Arboretum, fluxes of energy, water and CO2 have been monitored continuously over the forest catchment as a part of HydroKorea project. Using variograms, characteristic time scales of hydrologic parameters including precipitation, stream discharge, soil moisture and groundwater levels in response to the rainfall were evaluated to be less than 6 hours, 5 to 10 hours, less than 10 hours, and greater than a day, respectively. The range of timescale of each parameter could be attributed to the variation of corresponding rainfall events. In addition, the results show that there are temporal correlations among hydrologic parameters and the filtering effect indicating the small time-scale variation is gradually removed as precipitation moves downward to the deeper ground.
