内容記述 Numerical calculations of the long waves around a convex or concave bottom have been made to elucidate the behaviors of the waves around an obstacle and to determine an effective mesh length in the construction of a refraction diagram of tsunamis. Since the invading waves are treated as periodic ones in this work, a straightforward application of the theory to the evaluation of the effective mesh length for the leading part of tsunamis might be a little dubious (for the later phase, the present results are applicable). But when a dimension of the irregular part of the bottom (a simple hump) is small as compared with a wave-length of the incident waves, an interference effect produced by a coupling of the progressive and retrogressive waves is likely to be also small, so that the application of the results of the periodic waves might be still possible to the leading part of tsunamis dismissing the tip of the leading waves in which no interference effect taking place in the case of periodic waves is expected. In the present study, two typical tsunamis, i.e. the Chile Tsunami and Niigata Tsunami, have been employed to determine the actual negligible dimensions of the bottom irregularities. Furthermore, in the last section, some mention is made of the waves scattered by the submarine obstacle.
