Abstract

Takase River in the southeast of Aomori Prefecture is a tidal river with the compound channel. Filed measurement and laboratory experiments were carried out in order to understand mixing characteristics of river estuary in this paper. Salinities of Lake Ogawara were able to estimate from field data. Furthermore, experiments were performed in compound channel with the effects of narrow section. The transverse mixing coefficients were obtained from these results using diffusion equation, and compared with those in compound channel. It was showed that the mixing coefficients were related to the product density current parameter and cross-section of channel parameter. Therefore, it was found that Takase River estuary was influenced by compound channel from these results.
