- Abstract
The dynamics and energetic behavior of the tides in the Gulf of California were studied with their principal constituents. Three cases were chosen: the first included the MZ constituent; the second, the twoprincipal semidiurnal constituents; and the third, the seven most important tidal constituents in the gulf. The results show that the tide was successfully modeled for all constituents and for all cases. Itwas proved that small changes in the friction coefficient produce important errors in the tidal adjustment. The dynamics and energetic behavior of the tides did not change while varying the friction coefficient, even when more constituents were included. The most important forces that maintain the momentum balance in the gulf are the pressuregradient, Coriolis and friction, while in the southern gulf the mostimportant forces are in geostrophic balance. Advection is also important in the northern gulf and in the archipelago of the large islands. The regions where most of the tidal energy is dissipated are the northern gulf and the archipelago, especially in the Upper Gulf, Adar Bay, Ballenas Channel, and San Lorenzo and San Esteban sills. The inclusion of more constituents introduced more momentum and energy to thegulf, and part of this momentum and energy was transferred to the mean field and part to the low-frequency field. The results show that changes in the friction coefficient did not affect the tidal behavior in the gulf; nevertheless, the tidal energy dissipation estimated inside the gulf was affected.
