Abstract
A semi-empirical method for the tidal calibration of oceanographic models with two ocean approaches is developed. The same method may be extended to models with more than two approaches. Tidal functions (amplitude and phase) at reference stations are expressed in terms of the amplitudes and phases of the tide generators. A Taylor expansion is made about an initial set of conditions imposed on the generators. The result is a set of simultaneous equations, whose coefficients can be found experimentally. Then, knowing the response at the reference points to the initial generator conditions, corrections can be made to obtain any desired tide.The method is applied to the particular case of the Hecate Model. Examples of single- and multiple-component tides are given.
