| Zusammenfassung |
| In this paper we present a novel method to determine the time of
occurrence of tidal slack with a GPS receiver mounted on an anchored
buoy commonly used to delineate shipping lanes in estuaries and tidal
channels. Slack tide occurs when the tide changes direction from ebb
to flood flow or from flood to ebb. The determination of this point
in time is not only useful for shipping and salvaging, it is also
important information for calibrating tidal models, for determining
the maximum salt intrusion and for the further refinement of the
theory on tidal propagation. The accuracy of the timing is well
within 10 min and the method – able to operate in real time – is
relatively cheap and easy to implement on a permanent basis or
in short field campaigns. |
