Tidal current fluctuations in the Soya Current

Journal of the Oceanographical Society of Japan, 1987
Long-term current measurements were carried out near the Soya Strait in the Okhotsk Sea during a period from February 1980 to September 1982. The data were divided into five segments, each being 150 days long, and the tidal ellipse parameters of major axis, minor axis, orientation, and phase for the four major constituents (M2, S2, K1 and O1 tides ...

A Tidal Resource Evaluation-Based Method for Tidal Current Generation Farm Allocation Considering the Directionality of Tidal Currents

IEEE Transactions on Sustainable Energy, 2020
This article proposes a tidal resource evaluation-based planning method for profitable and reasonable allocations of tidal current generation farms (TCGFs). The directionality and variability of tidal current velocity (TCV) and their correlation are addressed. First, a TCGF power output model is developed.

Tidal current asymmetry in shallow estuaries and tidal creeks

Continental Shelf Research, 2002
Abstract We examine tidal asymmetry in a 100-km long coastal plain estuary, a 15-km long tidal creek closed at the end, and a small side channel of a coastal plain estuary closed at low water. Current meter and water depth data were harmonically analyzed for M2 and the M4 and M6 overtide.

Current vanes for measuring tidal currents in estuaries

Estuarine, Coastal and Shelf Science, 1989
Abstract Current vanes used as submerged drags are simple, reliable and inexpensive instruments for measuring instantaneous currents in shallow, tidal estuaries. They are superior to current crosses and well-suited for environmental surveys of estuarine current distributions.

Enhancement of semidiurnal tidal currents in the tidal inlets to Mississippi Sound

1988
Harmonic analysis of data collected in Mississippi Sound and the adjacent continental shelf in 1980 and 1981 indicates a pronounced difference between offshore and inshore tidal current regimes. On the shelf, the form number of the water levels and currents are approximately equal (6–7), while currents in the tidal inlets to Mississippi Sound have form

Effect of boundary geometries on tidal currents and tidal mixing

Journal of the Oceanographical Society of Japan, 1975
The effects of the coastal boundary geometries on the tidal currents and the tidal mixing are studied mainly on the basis of hydraulic model experiments. Mizushima-Nada Sea, which is located in the central part of Seto Inland Sea, and the whole Seto Inland Sea were chosen as the prototypes.

The vertical structure of tidal currents

Geophysical & Astrophysical Fluid Dynamics, 1982
Abstract The accuracy to which the vertical structure of tidal currents can be predicted is examined. Theoretical models for current structure are developed employing (a) a constant eddy viscosity E = e and (b) an eddy viscosity varying linearly with height above the sea bed z; E(z)=βz.

Tidal Currents of the North Sea

Proceedings of the Royal Society of Edinburgh, 1899
In the article “Tides” in the Encyclopœdia Britannica, Professor George Darwin, quoting Sir George B. Airy, remarks that the tides of the North Sea present a very remarkable peculiarity. Along the eastern coast of England as far as the mouth of the Thames, the tide-wave, coming from the Atlantic round the Orkney Islands, flows towards the south.
