A control volume based up-wind finite element method is applied to the semi-diurnal tidal flow in Ariake Sea and Yatushiro Sea. The behavior of water masses is investigated by tracing the fictitious water particles initially embedded in the distinctive eight regions as well as Euler's tidal residual flow. The main results are as follows : 1) At Hayasaki Seto, sea water flows out through the northern part and flows in through the southern part. 2) There exits a large clockwise vortex around Shishijima Island in Yatushiro Sea. 3) The water particles in the southern part of Ariake Sea flow into Yatushiro Sea through Yanagi Seto and into Hachiman Seto through Hondo Seto. 4) A few water particles in the northern part of Yatushiro Sea flow into Ariake Sea through Misumi Seto. 5) The water particles stagnate in Hachiman Seto and the northern parts of Ariake and Yatushiro Seas.
