In the previous paper, the wave radiation conditions in wave problems, their introduction into the variational principles and the simple numerical results are discussed, and the effectiveness of the new radiation conditions and the variational principles were shown. In the present paper, the numerical results for one-dimensional water wave problems not included in the previous paper are given. As expected in advance, the region required for the numerical solution is reduced drastically as compared with that required by the Sommerfeld-type formulation. Furthermore, the amplitude of the diverging wave is obtained in the process of the variational solution. Two-dimensional water wave problems are discussed briefly.
