alongshore sediment transport analyses for the shorelines adjacent to each of the inlets, and (d) one or more

sets of inlet hydrographic surveys, each set consisting of two surveys taken at different times, thereby

allowing measurement of the volume of sediment filling within the navigation channels in the time periods

between surveys.

(7) Ebb tidal energy flux. For each inlet selected, the parameter *E*∆T , representing the change of ebb

tidal energy flux across the ocean bar between natural and channel conditions, was computed and fixed as

constant for the given inlet using the following equation:

The next parameter is *E*w , the average daily wave energy flux per unit width of wave crest, offshore of the

site of interest. This parameter represents the intensity of sediment transport from the adjacent beaches to

the inlet environment. Daily wave energy flux can be expressed as
