| Sumario: | Tides and tidal currents are observed in Ensenada de la Paz, a shallow coastallagoon in Baja California Sur, México. The amplitudes of two semidiurnalharmonics increase towards the head and there is a notably phase lag with respect tothe mouth in the principal harmonics of surface tide. However, the amplitude of thefortnightly tide decreases toward the head. It is suggested that this behavior iscaused by an approximate balance between surface pressure gradient and quadraticbottom friction. The influence of both bottom friction and basin configuration onsurface tide are examined with a linear hydrodynamic model. Currents fall into twogroups: a tidally-driven inlet flow and an interior flow wherein nonlinearitiesappear to be important. The relative importance of nonlinear interactions on tidal velocities is analyzed with a simple model. |
