The continuous black curve is the observed sea level, and the continuous grey curve shows the sum of D2 and D4 harmonics, which produce a flattened tidal curve for a period of over 3 h at low water. You can view historical data and high/low tide ranges up to 6 days in advance. The asymmetry of the tidal curve results in significantly more rapid, short-lived ebb currents compared to the flood (Webber 1980).

Entry of coarse sediments into Southampton Water from the Solent is severely limited due to lack of suitable transport mechanisms although suspended sediments can move into the estuary. Dr Ivan Haigh, a tidal expert from the University of Southampton, described the reasons at an event at Highcliffe Sailing club as the combined effects of water sloshing across the Atlantic (a bit like in your bath) and spinning round because of the rotation of the Earth; this causes the water to slosh around a point which in fact is inland. Effect of nontidal current on the reversing currents are measured, in the direction of the nontidal cur- tidal current of Figure 3515b.
