Book Description
Abstract: "An investigation was undertaken to evaluate numerical models that can be used to predict harbor response to long-period wave excitation for both conventional harbors with deep drafts and artificial offshore ports in deep water. Numerical models using finite difference, hybrid finite element, and Lee's method solutions are discussed and compared with analytical solutions, hydraulic model data, and prototype field data. The hybrid finite element method of solution is shown to adequately predict periods of resonant peaks and modal water-surface elevation patterns in conventional and offshore harbors. Computational time requirements of this numerical model are shown to be sufficiciently low to make resonant response calculations economically feasible for a wide range of incident wave periods. Use of the hybrid finite element method to evaluate deep draft harbor design or modification and to aid hydraulic model studies of harbor oscillations is discussed."
