“…The reduction in the period of the free oscillation was calculated after the construction of the Isahaya dike and the reduced period was approximately 25 minutes. The reduced period in this experiment was close to the value calculated by Takikawa and Tabuchi (2002). Takikawa and Tabuchi (2002) investigated the reduction of 20 minutes in the period of the free oscillation after the construction of the Isahaya dike via the numerical experiment.…”

“…The degree of confidence in these approximations will depend on the accuracy with which the model reproduces the real system. In recent years, this approach has been widely used in studies of barrier schemes in the Bristol Channel (Heaps, 1972;Miles, 1979;Owen and Heaps, 1979), the Bay of Fundy (Garett, 1972;Greenberg, 1979;Duff, 1979), the west coast of Korea (Choi, 1978(Choi, , 1981(Choi, , 2001) and the Isahaya Bay in the Ariake Sea (Chiba and Takemoto, 2003;Kim and Yamashita, 2002;Kyozuka, 2002;Kyozuka et al, 2005;Nadaoka, 2002;Takikawa and Tabuchi, 2002). One of the most difficult and important tasks in this approach is that a sufficiently large region should be considered in the mathematical modeling.…”

A regional ocean tide model was designed to cover an area that is broad in scope and size, yet also provide a high degree of resolution for scientific and engineering interests. Using this model study, the changes in the tidal regime in the Ariake Sea after the construction of the dike in the Isahaya Bay were simulated in terms of the tide, tidal current, bottom shear stress, tidal energy dissipation and transport potential and free oscillation mode. The simulation results indicated the impact of the dike construction on the tidal regime by showing the general decreases in the tide, tidal current, the capacities of sediment transport and free oscillation period due to the construction of the dike.

Physical, biological, and chemical approaches should be comprehensively taken to evaluate the environmental conditions of a sea area with tidal mud flats like the Ariake Sea. In this study, a quantitative echo sounder was used to develop an acoustic method for remote and planimetric on-board observation on the distribution of the sea water and the floating mud layer which contain toxic substances like hydrogen sulfide. Based on the acoustic data, accordingly, material balance in tidal mud flats and underwater environmental conditions were evaluated. Specifically, a correlation between underwater acoustic data and the amount of hydrogen sulfide was established based on the indexes of transducer frequency and echo sounder manufacturer.
