Martha, SC and Bora, SN and Chakrabarti, A (2007) Oblique water-wave scattering by small undulation on a porous sea-bed. In: Applied Ocean Research, 29 (1-2). pp. 86-90.
The problem of scattering of obliquely incident surface water waves by small undulation on a sea-bed is considered for solution by assuming that the bed is composed of porous material of a specific type. The reflection and transmission coefficients are determined approximately after assuming a perturbation analysis in conjunction with the Fourier transform technique, in terms of the first order of smallness of an undulation parameter $\varepsilon$ introduced in the description of the sea-bed. The special case of a patch of sinusoidal ripples on the bed is handled in detail and numerical results are presented graphically.
