The importance of interaction between surface water and groundwater has been increased for the understanding and analyzing hydrological cycle in natural stream system. In this study, the interaction between surface water and groundwater is qualitatively analyzed by using a field measurement of water level and temperature in Guamcheon stream, South Korea. The results show that temperature measurement is necessary to assess the interaction between surface water and ground water not only water level. The interactions between surface water and groundwater in short stream can be analyzed by using this method and the accuracy of stream-groundwater interactions can be enhanced in the concept of hydrological analysis by adding the temperature variation data. Consequently, this method based on field measurement can be expected as a basic procedure for qualitative study on stream-groundwater interactions.
