In the present work a hybrid boundary element method is used. in conjunction with a coupled mode model and perfectly matched layer model. for obtaining the solution of the propagation/diffraction/radiation problems of floating bodies in variable bathymetry regions. The implemented methodology is free of mild-slope assumptions and restrictions. https://www.hindigyanvishv.com/top-super-Centehua-Distressed-Southwestern-Aztec-Area-Rug-special-buy/
