ST10: Erosion toward equilibrium, random waves 



Test ST10 was the first and the longest test (21 hr of wave action) of 

 SUPERTANK. This test was conducted to observe beach response to erosive 

 random waves together with the associated hydrodynamics and sediment trans- 

 port (Figure 1-8). Some changes were made in the spectral width of the ran- 

 dom waves to observe the change in bar morphology and hydrodynamics. 

 Several monochromatic wave runs were made for the acoustic instrumentation 

 group. The combinations of random wave runs and monochromatic wave 

 runs in the same test are expected to provide valuable data for improving 

 beach profile change numerical simulation models.
