| 概要 |
A two-dimensional depth-integrated hydrodynamic model with spatial resolution of 1 km is established and used to calculate the major four tidal constituents and three shallow water tides inside and ou...tside of the Seto Inland Sea (SIS), Japan. Comparisons with observations show good reproduction of the amplitudes and phases of the M_2, S_2, K_1, and O_1 tides and tidal currents. Inside the SIS, large M_4 and MS_4 tides as well as strong tide-induced residual currents are found around the straits and narrow channels; outside of the SIS, a westward residual current is found along the shelf slope. The tide-induced residual currents have apparent fortnightly variations. Inside the SIS, for instance, the tide-induced residual currents around the straits decrease from the spring tide to the neap tide; outside the SIS, the westward residual current along the shelf slope appears at spring tide but disappears at neap tide. Such a well-calibrated tidal model is a necessary step for the success of a circulation modeling in the SIS.続きを見る
