Engineering approximations to nonlinear deepwater waves
Recent measurements of wave kinematic indicate that the horizontal wave velocity is smaller at the crest and higher (more negative) in the trough than predicted by the Stokes higher order theories which are normally used in a deterministic design process. This has led to postulation of engineering methods for description of wave kinematics1,2A methodology has been developed to establish second order corrections to the engineeringmethods. The purpose is to find a description of the wave kinematics which predicts measured behaviour with good degree of accuracy.The methodology has been applied to the engineering methods proposed by Wheeler1 and Chakrabarti.2 The second order Chakrabarti approximation (the ‘alternative approximation’) demonstrates good agreement with measured wave kinematics.
