In this article, a new approach to tidal harmonic analysis is introduced. This approach incorporates more constituents in the least squares method for a fixed duration of noise-free tidal record and results in a more accurate tidal prediction. Moreover, it is demonstrated that 135 days of hourly data, which is significantly less than 369 days data in the Rayleigh criterion, is sufficient for th...

based on 11 years of topex/poseidon satellite altimetry and coastal tide gauge sea level observations, four tidal constituents, namely o1, k1, m2 and s2, are modeled for the persian gulf and oman sea using a time-wise approach according to the following details. by selecting the cycle 100 as the reference, 772 points on 12 paths along the track of the altimetry satellite footprints over the per...

using tidal potential, the effect of tide on the gravity field, crustal deformation due to tidal force, and gravity variations resulted from the crustal deformation are presented. tidal potential is divided into constant and periodic (diurnal and semi-diurnal) constituents, and for each constituents crustal displacements in radial, south-north, and east-west directions are computed. the aforeme...

Traditionally, tidal prediction was carried out using the harmonic method, which is based on the identification of the harmonic constituents existing in the tidal record. Unfortunately, however, unless long tidal records are available at the tide gauges, some important tidal constituents may not be identified. This, in turn, deteriorates the accuracy of the tidal prediction. Additionally, tidal...

Bushehr Bay is situated along the northern Iranian coasts of the Persian Gulf, between 28°52΄ and 29°5΄ north latitude and 50°42΄ and 50°52΄east longitude. In this study COHERENS, which is a threedimensional hydrodynamic model, was employed to simulate surface and under surface currents in the Bushehr Bay. The atmospheric forces and four main tidal constituents M2, S2, K1, O1 and also boundary ...

Tidal dynamics of shallow estuaries and lagoons is a complex matter that has attracted the attention of a large number of researchers over the last few decades. The main purpose of the present work is to study the intricate tidal dynamics of the Tagus estuary, which states as the largest estuary of the Iberian Peninsula and one of the most important wetlands in Portugal and Europe. Tagus has la...

[1] Time series of surface elevation and current velocity in the vicinity of the Chesapeake Bay entrance are assimilated into a linear, barotropic model using an iterative adjoint method. Tide surface elevations, NOAA-NOS tidal data, moored acoustic Doppler current profiler (ADCP), and ocean surface current radar (OSCR) data are included in the assimilation. Data are analyzed for three tidal co...

Eight major tidal constituents in the Sea of Okhotsk have been investigated using a numerical solution of tidal equations on a 59 space grid. The tides are dominated by the diurnal constituents. Diurnal tidal currents are enhanced in Shelikhov Bay and Penzhinskaya Guba, at Kashevarov Bank, in proximity to the Kuril Islands and at a few smaller locations. The major energy sink for diurnal tides ...
