Effects of Reflective Vertical Structures Permeability on Random Wave Kinematics
Publication: Journal of Waterway, Port, Coastal, and Ocean Engineering
Volume 123, Issue 6
Abstract
Two simple numerical models are presented to estimate the root-mean-squared velocity for random nonbreaking waves obliquely incident on partially reflecting coastal structures. The structures considered are vertical permeable structures with a free surface or crowned. The models are also capable of simulating the case of an impermeable vertical wall. Results depend on the input spectrum, breakwater geometry, and porous material characteristics. All this information is considered in the calculated complex reflection coefficient, which has information not only on the modulus of the reflection for each of the wave components, but also on the reflection-induced phase shift.
