Description 849-858
Present
study consists the interaction of surface waves with submarine pit breakwaters. A vertically-integrated nonlinear dispersive wave model with
inclusion of a semi-empirical wave breaking effect, in non-orthogonal
curvilinear coordinate system is used for simulating waves. The
staggered grid system is used. Matrix equation of the finite difference method
is solved through an iterative approach at each time step. Numerical method results in implicit
formulations for the momentum equations and explicit formulation for the
continuity equation. The numerical model has been validated through comparisons
of computational results with experimental measurements of the wave propagation
over an asymmetrical trapezoidal bar, over shoals and the regular wave
diffraction results for rectangular pit. Simulations show an acceptable level
of agreement and give confidence for practical applications.
