영문 초록

  A numerical model using Hybrid Element Method(HEM) is carried out for the prediction of resonance in a harbor which are induced by the incident long-period waves. A shallow water wave equation including bottom friction is used as the governing equation and a partial absorbing boundary condition is used on closed boundaries is accepted, Chen and Mei(1974)"s concept which uses finite element net in the inner region and analytical solution of Helmholtz equation in the outer region. The mumerical model is applied to a fully open rectangular harbor to prove its validity and is also applied to Gamcheon Harbor, intend to analyze Long-period Resonance. It is noted that the period of Helmholtz resonant mode of Gamcheon Harbor is 32.7 minutes and the second and third resonant periods appear at 10.7 minutes and 6.5 minutes, respectively.
