Abstract:
Wave structure interaction problem having thick vertical barrier
over an arbitrary seabed is analysed for its solution. The associated
boundary value problem is handled using a coupled eigenfunction
expansion–boundary element method. This method converts the
boundary value problem into integral equation over the physical
boundaries. The physical boundaries are discretised into afinite number of elements and hence the integral equation give rise to a system of linear algebraic equations. Finally, the system of equations is
solved to obtain the physical quantities, namely, the reflection and
transmission coefficients. For ensuring the correctness of these physical quantities, the energy balance relation is derived and verified.
The present results are also verified by comparing the results available in the literature. The present study reveals that the width and
height of the structure along with the undulated seabed play an
important role to construct an effective wave barrier to protect various marine facilities from wave attack and also helpful to create the
tranquility zone on the lee side of the structure.
