The problem of a fixed rectangular structure of unit width in a
train of simple harmonic normally-incident waves is modeled. The solution
allows for variable (1) length and draft of structure, (2) differing
depths in the three (fore, aft, and beneath the structure) distinct
regions, and (3) wave period. The...
This study includes an analytical solution to the wave-current
barrier interaction problem and large scale experiments to validate the
theory.
The boundary value problem is solved mathematically by characterizing
the flow field and barrier motion separately, then coupling
the relationships with the appropriate kinematic and dynamic boundary
conditions.
The flow...
The objective of this study is the development and
verification of an analytical solution for an unsteady
flow field partially occupied by a permeable structure.
Flow is induced by a small amplitude incident wave
train and the permeable structure may contain multilayered
anisotropic but homogeneous material. The analytical
solution developed...
Problems associated with quantification of deep water wave kinematics
and dynamics are examined. Summaries of Stokes' theory and Dean's
stream function theory are reported. A computer algorithm is developed
to solve the hydrodynamic characteristics for Stokes' fifth and third
order and linear theories. Tests are initiated to verify the results...
Directional wave spectra have been estimated in this study based
upon simultaneous subsurface measurements of current and pressure.
Two previously developed methods, the stochastic and deterministic
approaches, have been reviewed and restudied. It is demonstrated by
means of the Correlation Theorem that the stochastic and deterministic
approaches are, under certain...
Geotextiles are synthetic fabrics which may be substituted for
graded aggregate to protect ocean and coastal structures from erosion
and soil instability adjacent to the structure. They are commonly
used as a filter and as a structural membrane between an undisturbed
sediment surface below and an erosion resistant coarse aggregate...
