The Takase River is important in the southeast of Aomori Prefecture and its estuary is typical tidal river. Mixing of salt-water intrusion in compound channel is very complicated. The field measurement is performed to study the mixing characteristics in the compound channel of the Takase River estuary. The salinity concentrations are measured by the thermometers and by the salinometers in 29 stations of the field. The water temperature is changed into the salinity concentration. The results of this study showed that patterns of the horizontal salinity mixing in the compound channel at flood tide is different from those at ebb tide.
