Equations for surface waves and interfacial waves and their relations in a basin with depth iscontinuities were given by Lamb, Le mehaute, Takano, and Rattray. If the length of the bay is much larger than the width, and the curvature of the bay aixs is small, it is possible to consider that the surface long waves, i.e. the tidal waves and the interfacial long waves generated in these basins can be treated as a one dimensional problem. The bay can be divided into many rectangular segments as shown in Fig. 1, and each of the divided segments corresponds to any of the model segments as shown in Fig. 2. The basic equations for the surface and the interfacial long waves in the model canals are given on the basis of Lamb and Takano's theory. The numerical computations for the surface long waves and the interfacial waves generated in a two layer basin with variation in depth and width. can be carried out by using the basic equations in the model canals.
