Hyporheic zone water is found by the water temperature characteristic and impact of micro scale riverbed structure on streamwater chemistries was examined through field measurement at mountain stream. For streamwater chemistries, water exchange between hyporheic zone and streamwater was found to be effective and causes denitrification in some locations. These results ware influenced by riverbed structures. By the influence of rainfall, the concentration of NO3− was declined and Cl− was increased. The exchange between soil and streamwater cause such phenomena. There ware negative correlations in SO42− and NO3−. Therefore the existence of hyporheic zone water was supported by this negative correlation.
