註釋Methods used in analyzing flow through tidal entrances on sandy coasts make assumptions regarding the geometry of the inlets and related flow regime, which depart substantially from flow conditions at real entrances. A volume of reduced data on tides, currents and the geometry of tidal entrances is contained in the Tide Tables, Tidal Current Tables and navigation charts of National Ocean Survey. The described approach makes use of these data to characterize the flow in real inlets by means of empirical coefficients which are defined by a simple flow relationship. The evaluation of the published data pertaining to the hydraulics of entrances indicates that the data are sufficiently accurate and representative, despite some yet unexplained discrepancies, to permit the determination of discharge coefficients of inlets, and to identify categories of entrances with characteristic flow regimes.
