L字水路における津波[IV] | Tsunami in an L-shaped Canal [IV] : the fourth Approximation
1966
Momoi, Takao
In this work, numerical solutions of the waves in the vicinity of the crooked part of an L-shaped canal including the buffer domain were obtained under the fourth approximation. Unlike the preceding works, the expressions of the buffer domain are incorporated into the simultaneous equations as members of the unknowns in order to examine numerically the behavior of the waves in this domain. Then the variations of the amplitudes and phases are illustrated figuratively for the range 0<kd<1.0 (k: a wave number of the incident wave, d: a width of the canal).
