Experimental setup in CERC's tank. Wave data were also collected in CERC's by by wave tank. The setup in this tank was designed to obtain data on the shoaling and breaking of irregular waves. Ten parallel wire wave gages were used: three gages over the horizontal tank bottom and seven over a 1 on 3 concrete slope. Figure 6 shows a profile view of the test setup and gage locations; the data are tabulated in Appendix D. Table 1 provides a summary of the wave conditions, data and test setups used in the laboratory tests. b. Procedures and Analysis. All the waves were generated using hydrauli- cally actuated piston-type wave makers. The monochromatic waves studied included waves with sinusoidal blade motion with Ursell numbers less than 25 and cnoidal waves with Ursell numbers greater than 25. The Ursell number, Uj^, is defined Ut, = HL (1) where H is the average wave height over the flat bottom part of the wave tank and L^ the local wavelength, calculated using linear theory and defined by.
