摘要：Conventional ocean wave theories are based on an assumption of a rigid impermeable seabed, which are difficult to simulate the effects of porous seabed on wave propagation. The major intention is to establish modified wave dispersion equation which can consider the interaction of wave and seabed on the basis of dynamic analysis by employing the complex wave number. Analytical solutions of two non-dimensional parameters of wave length ratio and energy factor are given for comparative studies in different situations of seabed thickness, soil permeability, degree of saturation and wave circle frequency. The results show that wave profile will be attenuated and wave length will be changed subjected to the effects of porous seabed.
