Submerged structures are frequently used in coastal engineering applications, such as tunnel and pipeline protection works, breakwaters, and artificial reefs. Although a significant number of research works have focused on low-crested structures, there is far less research into deeply submerged structures. In most research, lightly-sloped, uniform cross-sectioned submerged structures with specific crest elevations are considered. The present thesis deals with the three-dimensional physical and numerical modelling of the interaction of irregular waves with a large-scale three-dimensional submerged structure. It aims to advance the understanding of the structure's influence on the irregular wave field, the wave-induced velocities along the structure crest, and the wave-induced currents. The ability of a nonlinear Boussinesq wave model to simulate these processes is also investigated and assessed. Analysis was performed on a multitude of data, including--but not limited to--wave heights, wave periods, wave energy spectra, energy transfer functions, reflection analyses, and wave-induced velocities. In general, the analysis and comparison performed showed that the numerical model provided a modestly accurate representation of the physical modelling results.

Mathematical Techniques for Wave Interaction with Flexible Structures is a thoughtful compilation of the various mathematical techniques used to deal with wave structure interaction problems. The book emphasizes unique determination of the solution for a class of physical problems associated with Laplace- or Helmholtz-type equations satisfying higher order boundary conditions with the applications of the theory of ordinary and partial differential equations, Fourier analysis, and more. Features: Provides a focused mathematical treatment for gravity wave interaction with floating and submerged flexible structures Highlights solution methods for a special class of boundary value problems in wave structure interaction Introduces and expands upon differential equations and the fundamentals of wave structure interaction problems This is an ideal handbook for naval architects, ocean engineers, and geophysicists dealing with the design of floating and/or flexible marine structures. The book’s underlying mathematical tools can be easily extended to deal with physical problems in the area of acoustics, electromagnetic waves, wave propagation in elastic media, and solid‐state physics. Designed for both the classroom and independent study, Mathematical Techniques for Wave Interaction with Flexible Structures enables readers to appreciate and apply the mathematical tools of wave structure interaction research to their own work.

This report describes the analytical method and numerical procedure for the calculation of the wave pressure distribution and resulting induced forces and moments acting on large displacement bodies in the sea. The added mass and damping coefficients for the structure oscillating in all six degrees of freedom is computed. Then, the hydrodynamic coefficients associated with both the wave/structure interaction and the oscillation of the structure are determined by use of a Green's function method using quadralateral elements of constant source strength which applies to large structures of rather general shape. The analysis is based on linear theory and viscous effects are neglected on the basis that the size of the structure is large in relation to the amplitude of the incident wave. Also, the equations of motion for a free-floating body are developed which yields the dynamic response of a floating body with linear mooring line forces. Finally, the computer program capable of carrying out the numerical calculations is outlined and the input/output is discussed in some detail. (Author).

The practical and rigorous solutions of the potential problem associated with the harmonic oscillation of a submerged rigid body of arbitrary shape is presented. The use of Green's function reduces the determination of the potential to the solution of an integral equation. The integral equation is solved numerically and the dependency of the hydrodynamic quantities such as added mass and damping coefficients of the object on the frequency of the oscillation is established. Several checks are made on the numerical results. These include the Haskind's relations check, an energy check for the radiation problem, and comparisons with closed form solutions. (Author).
