| With the application of a two-dimensional nonlinear hydrodynamical-numerical semi-implicit model, the principal tides M(2), S(2), K(2), N(2), K(1), P(1) and O(1) were studied. Energy budgets of the semi-diurnal M(2) and S(2) were calculated separately. The linear sum of these budgets was compared with the tidal energy budget obtained when these two tidal constituents interact. Since a quadratic form for the bottom friction was used, remarkable differences were found. The results show that in the area of the Colorado River delta, the dissipation of tidal energy is very strong. Intense tidal currents were observed in the same region and over the Salsipuedes Sill. Energy budgets calculated for forcing waves of different periods, but of the same amplitude,... |
