These releases occurred at the beginning of an ebb tide, and dispersions of the drogues and fruits were monitored for 1 tidal day.
Shortening the duration of the dye injection from several days to 1 tidal day (24.
The first approach considered the entire data set, for which the average dye concentrations per tidal day were determined.
To account for potential loss of dye from these factors, a value of 3% loss per tidal day was factored into dilution calculations, based on findings from field and laboratory studies (Hefting & O'Connell 1966, Tai & Rathbun 1988, Kilpatrick 1993).
The overall steady-state dilution of the dye based on the tidal day average for station 2 was 8.
These data suggest that station 3 was influenced primarily by water associated with a flood tide on tidal day 3, a portion of which was dye-tagged wastewater effluent that was pushed back up into Mobile Bay.
Daily tides; having a period or cycle of approximately one tidal day.
The difference in height between the two High Waters or the two Low Waters of each tidal day.
Twice daily tides; having a period/cycle of approximately one-half of a tidal day.
The average of the Higher High Water height on all tidal days observed during a tidal datum epoch.
The average of the Lower Low Water height of all tidal days during the tidal datum epoch.
The average of the Lower Low Water height on all tidal days observed during a tidal datum epoch.
