Example 2
This example presents results for two wave/current conditions from the idealized inlet laboratory
study. The data have been converted to prototype (field) scale in the figures, using a scale of
1:50. Figure 2 shows a one-dimensional slice of the bathymetry from the deep offshore section
near the wave generator (x = 0 ft) to the outer edge of the ebb shoal (x = 1,000 ft) and between
the jetties (x = 1,500-2,500 ft).
