To understand the temporal dynamics of stream water temperature for hydrological aspect, we examined steam water temperature, air temperature, runoff, and precipitation in 23.4 ha a natural forested catchment, Gangwon-do, Korea. The data was collected during limited period (i.e., spring, summer, and fall except for winter) from 2017 to 2018 year. For measurement of stream water temperature and runoff, intakes of sampler was located with parshall flumes in the gauging station of catchment. Both of precipitation and air temperature were collected using HOBO tipping-bucket rain gauge. Stream water temperature was correlated with air temperature and tended to be lower than air temperature. Correlation analysis was conducted by stream water temperature with air temperature, runoff, and precitation during each seasonal changes. Stream water temperature was correlated with each different parameter by seasonal character. Regression analysis could be developed due to contribution of air temperature with runoff and precipitation to respond stream water temperature. Therefore, method using parameters of temporal variation could be recommended for predicting stream water temperature with each season. This study also indicated the changes in stream water temperature based on hydrological connectives and/or processes with seasonal character within a natural forested catchment.
