Abstract : Some initial value problems are studied regarding the radiation and scattering of gravity waves by thin vertical plates in an infinitely deep ocean. The general solution is obtained by transforming the boundary value problem to one of the Riemann-Hilbert type. Explicit investigations are made for the large time behavior of the free surface elevation for the case of a rolling plate, and for the Cauchy-Poisson problems in the presence of a stationary plate. By taking the limit as t approaches infinity, the steady state solution is derived for a harmonic point pressure acting on the free surface near a vertical barrier. (Author)
