Abstrakt: It is often necessary to compare the flushing of coastal inlets in selecting sites for aquaculture or in making recommendations on pollution hazards. We derive an expression for a reference flushing time. [This symbol cannot be presented in ASCII format] in which h is the mean depth of the inlet, (E-R) is the net evaporation rate, S1 is the salinity of the open ocean, S2 is the (volume) average salinity in the inlet and ΔS = S2-S1. τ0 is easily evaluated from simply obtained data sets, especially in a steady-state situation, or for an harmonic annual cycle. We show that τ0 is a good estimate of the flushing time for sources within the body of the inlet. [ABSTRACT FROM AUTHOR]
