The drift currents from the incoming waves transport sediments in a south westerly direction, creating the incipient barrier after breaking down the two-layered flow during the spring and neap tides (Chawla et al., 2008), as well as during the same tidal cycle with less saline ebb current surface and marine current flows.
The USEPA spreadsheet [27] is used to calculate the initial dilution during spring and neap tides for both sites.
Average and standard deviation (between brackets) of WIND (speed, m.[s.sup.-1]) and PPT (precipitation rates mm.[day.sup.-1]) for surveys held in 2006 and 2007, spring and neap tides.

"We are on neap tides at the moment and there was enough space for the animal to remain there safely overnight," said coastguard Dave Millar.
On neap tides, it will go out less far and there will be less time available for rockpooling.
NSW is subject to a diurnal tide that has a maximum range of about 1.8 metres for spring tides and about 1.5 metres for neap tides. There is very little difference between the times of tides at NSW ports and that of Sydney, which is used as the reference.
The smallest tidal differences, called "neap tides," come at the first and third quarters of the lunar month, when the forces exerted by lunar and solar gravity do more to cancel each other.
Neap tides occur two days after the first and last quarter.
During neap tides the tidal range is relatively small, so little water washes the banks in the wetlands.
For example, Pugh discusses the "age of the tide", the lag of spring and neap tides behind full and new moon at which the solar and lunar tidal forces combine.
Suspended sediment transects in the estuary were carried out along the salinity gradient during inflowing and outflowing water for spring and neap tides in dry and wet seasons during the 2-year study period (1994-96).
