water, small waves were run to condition the profile to a natural state after the 

 sand-moving operations. Figure 1-19 shows three water spouts at the wall 

 upon wave impact. 



ST DO: Berm flooding. Test 2 of 2 



Another berm was constructed to examine runup and swash transport. 

 The same waves were run as in ST90, but with the water level 0.6 m lower. 

 Final runs were done with a narrow-banded spectrum and with monochromatic 

 waves to promote break-point bar growth. 



STEO: Laser Doppler velocimeter (LDV), Test 1 of 2 



Monochromatic waves with short periods were run for data collection by 

 the LDV in the offshore. 



ST FO: Laser Doppler velocimeter. Test 2 of 2 



Longer period monochromatic waves were run for LDV measurements.
