Hydrodynamic Data from
Fixed-bed Experiments
The primary data sets for Test 6N (regular waves) and Test 8E (irregular
waves) are provided in tabular form in Table A-1 and Table A-2, respectively.
Each table lists the measured mean longshore current at transects Y19, Y23, Y27,
and Y31, as well as the longshore-averaged value for these four transects, Vavg;
the still-water depth, d; the longshore-averaged value of wave setup or setdown,
ηavg, and wave height, Havg. The energy-based significant wave height, listed for
Test 8E, is based on using a lower cutoff frequency of 0.2 Hz (i.e., 0.5 Fp), to
remove the low-frequency energy from the water surface elevation time series.
The cross-shore (x-axis) positions of the measurements are listed in the standard
basin coordinates. The still-water depth can be calculated as
d = x/30-0.1, for 3.0 m < x < 18.0 m
(A-1)
d = x/18 0.5, for 18.0 m < x < 21.0 m
(A-2)
d = 0.667 m, for x > 21.0 m
(A-3)
