Sedimentary geology of the offshore sand waves has been attracted more attention on the morphological features and internal structures, because the offshore sand waves have been taked for favorable oil and gas reservoir bed. Recently, it′s found that the migration of offshore sand waves has a disastrous impact on the offshore engineering and facilities as the harbor,dock, navigation channel, submarine cable, offshore drilling and pipeline, etc. with the increasing exploitation of the marine resources. Consequently, it′s highly required to evaluate and predict quantitatively, the migration rate of offshore sand waves. Improvement on the migration rate evaluation is approached to the offshore sand waves based on previous studies, which means that the equilibrium range spectrum analysis of sand waves observed is utlized to find the functional relationship between the density function of time spectrum and bed shear stress, migration rate, etc., and then, the theorectical formula to estimate the migration rate of sand waves.
