The interaction of oblique incidentwaves with a moored finite floating membrane is analyzed for finite water depth with changes in bottom topography. The solution for the physical problem is obtained based on linearized water wave theory using the eigenfunction expansion method and orthogonal mode-coupling relation. The numerical computations are performed for the reflection coefficient, transmission coefficients and vertical deflections to understand the effect of mooring and changes in bottom topography on the wave interaction with the floating membrane. Energy relation for oblique gravity wave scattering by floating membrane where there are changes in bottom topography is used to check the accuracy of the computation. It is observed that due to the presence of the moored floating membrane the amplitude of the transmitted wave diminishes significantly. The changes in the reflection and transmission coefficient are also observed due to the variation in the bottom topography and also to the changing of the tension parameter of the floating membrane. The present study shows the effect of spring mooring on the wave propagation due to the presence of floating membrane with changes in bottom topography.
