The current velocity was recorded simultaneously with salinity in the water column during a tidal cycle. In a general way, we can observe that the values of velocity are higher during the flood ebb than during the flood, in the inner system, whereas in the flood tidal deltas and spill-over lobes (Bay and Mouth complex) the dominant current is the flood.
The estimated flushing times at both sites with this method depict that the load removed from the Karachi harbor estuary and Gizri/Korangi creek takes 30 tidal cycles to 46 tidal cycles respectively.
Water flow through the ambient- and low-flow channels was characterized through repeated measurements of current velocity over 2 complete tidal cycles (ebb and flood).
In the colder months, the movement of ice over a tidal cycle directly influences the amount and configuration of open water in the polynya over the short term.
The fortnightly tidal cycle at Wardell showed that suspended sediment concentrations during the neap tides were less than during the spring tides, due to decreasing tidal amplitude (1.8 to 1.2 m) and peak current velocity (0.49 to 0.39 m/s).
bifasciatum at San Blas and Barbados from that perspective, because those two sites differ in the structure of their tidal regimes (at Barbados the tidal range is twice as large and the semidiurnal tidal signal is stronger) and in the closeness of the linkage between the tidal and "lunar" cycles (both cycles have a [approximately]29.5-d period at Barbados, while the tidal cycle is [approximately]2 d shorter than the lunar cycle at San Bias: Sponaugle and Cowen 1997 and see Discussion: Short-term dynamics of spawning).
- The last remaining step, which is unique to intertidal systems, is to calculate the timing of exposure to the aerial environment as a function of the tidal cycle. Denny and Paine (1998) have recently shown that tidal cycles vary in amplitude over an [approximately]18.6-yr cycle due to fluctuations in lunar inclination, which can result in variability in exposure times of up to 30-40 min, particularly in higher regions of the intertidal ([greater than] 1 m + Mean Lowest Low Water [MLLW]).
Lifeboat operations manager Peter Williams said: "At certain times during the tidal cycle, the bay quickly fills with fast moving water.
Because of the complexities of topography, tidal cycle, season, and weather that vary between sites, we did not attempt to make quantitative comparisons of growth between locations.
The nacelle buoyancy means that it floats, so it can be easily installed and retrieved in a single tidal cycle using small vessels, thereby reducing installation and maintenance costs.
